Episode 70 – "Hindenburg Mystery, Crocodile Zig Zags"

  • Original airdate: January 10, 2007

Hindenburg Mystery

Myth statement Status Notes
The Hindenburg was destroyed by the highly flammable doping compound used to paint it, not the hydrogen used to give it lift. Busted Using the same compounds used in the Hindenburg's paint, the MythBusters discovered that they could combine to form highly incendiary thermite. However, the actual proportions of components in the paint burned too slowly to match the film footage of the Hindenburg disaster. A scale model of the Hindenburg using the same paint and placed in a hydrogen-rich environment took about a minute to burn and did look very similar to the original events. In the end, they concluded that the Hindenburg's demise could be attributed to both the hydrogen and the paint, and they agreed that the paint by itself was not responsible for the rapid burning of the airship. They also pointed out that if actual thermite covered the Hindenburg, it would make the airship too heavy to fly.

Crocodile Zig Zags

Myth statement Status Notes
A person can outrun a crocodile by running in zig-zags. Busted The MythBusters used various methods to try to get both crocodiles and alligators to chase them using lures or openly provoking the animals. However, all of the crocodiles and alligators they experimented with either did not react, followed them slowly, or made a single lunge. Through further study, the MythBusters concluded that because crocodiles and alligators rely on ambushing their prey, it is unlikely they would engage in a prolonged chase. In addition, the MythBusters advised viewers that the best way to avoid a crocodile or alligator is to stay away from the water.

Episode 71 – "Pirate Special"

  • Original airdate: January 17, 2007
Myth statement Status Notes
The splinter fragmentation caused by a cannonball's impact with the wooden hull of a pirate ship can kill more pirates than direct impacts with the cannonball itself. Busted Using a simple air cannon and four pig corpses, the MythBusters proved that a cannonball could penetrate at least four pigs with a single shot. However, when fired at a wooden wall, the splinters did not have enough power to pierce any of the pigs. In order to fully confirm or bust the myth, the MythBusters used an authentic Civil War era cannon. Through preliminary testing, they proved that the Civil War cannon was significantly more powerful than the air cannon. However, when fired at the wooden wall, none of the splinters managed to penetrate the pigs with enough force to be lethal. Therefore, the MythBusters concluded that getting hit with a cannonball was more deadly than the splinters it creates.
Pirates wore eyepatches to preserve night vision in one eye. Plausible This myth works under the assumption that the eye covered with the eyepatch is already accustomed to low light conditions, while the other eye must take time to accustom. The MythBusters were sent into a pirate-themed obstacle course (which was dark, and Adam and Jamie had not seen the course in light, let alone the layout) with light-accustomed eyes and were told to complete certain objectives. Their movements were hampered by the darkness and it took them five minutes to finish. When they went back in with an eye that had been covered for thirty minutes, the MythBusters were able to complete the test in a fraction of the time. As a control test, the MythBusters then went back into the same exact room with light-accustomed eyes and ran into the same difficulty as the first test. The myth was deemed plausible rather than confirmed because there is no recorded historical precedent for this myth.
A person can safely slow a fall by using a knife to cut a sail. Busted Through various small scale tests, the MythBusters found that sails were not made in one piece, but in fact had a number of seams where the sail was folded over into several layers, making them harder to cut. Also, the sharpness of the knife plays a major role in the myth. If the knife is too sharp, the pirate falls too fast. If the knife is too dull, it would be unable to cut through the seams. In the full scale test, Tory attempted the myth himself by using a moderately sharp knife on a full-size sail. However, every time he attempted the myth, his knife would hit the seam and pop out of the sail. In the end, the MythBusters concluded that there is no possible way that a pirate's knife would be able to be at the perfect balance between dullness and sharpness to safely cut through a sail.
Pirates used rum as a means of cleaning clothes in addition to drinking it. Busted Using rum, modern detergent, period soap, and even urine (allowed to become stale and transform into ammonia), the MythBusters tested to see if rum could be used to clean up blood, tar, and orange stains on fabric. However, after the tests, the results were the modern detergent and urine doing fairly well, but almost no effect from the period soap and rum. Also, Jamie jokingly points out that pirates would more likely drink the rum than use it to clean their clothes.

Episode 72 – "Underwater Car"

  • Original airdate: January 24, 2007

Underwater Car

According to the American Automobile Association, an estimated 11,000 vehicles crashed into bodies of water in one year. The MythBusters tested various methods of escaping a sinking car, in this case a Ford Taurus.

Myth statement Status Notes
If a car falls into the water and becomes submerged, the door cannot be opened until the interior is flooded. Confirmed The pressure differential between outside and inside when the car is submerged is too great for a man to force the door, and the pressure must first be equalized, which means the interior must be flooded first. Adam was forced to resort to emergency air in his first test, since he expended a great deal of energy (and oxygen) in attempting to open the door. A second test later showed it to be possible to escape the car simply by opening the door, but only by remaining calm and not attempting to open the door until the interior is well and truly flooded, so as to conserve oxygen while holding one's breath.

Having confirmed the myth, Adam and Jamie expanded on the myth to determine in what situations and which methods of escaping the car are feasible.

A person can escape a car that has fallen into the water...

Myth statement Status Notes
...immediately after hitting the water. Confirmed There is not enough water pressing on the door to keep it shut. Adam escapes easily. soon as the water inside the car is up to one's waist. Confirmed Adam barely manages to force the door open and is even briefly submerged before he emerges from the car. soon as water covers the car window from the outside. Busted At this point, the pressure difference has become too great. Adam is unable to escape.

They also proved that breaking the window is a viable way to escape a sinking car, if one has a suitable tool. Though breaking the window quickly floods the interior, Adam only has to hold his breath for a few seconds before climbing through the simulated "broken window" and surfacing. A person can open a window in a submerged car by...

Myth statement Status Notes
...using a manual window crank. Busted Using a test weight of 350 pounds (160 kg) (equivalent to pressure differential from just two feet of immersion), the pressure of the window glass against the frame is so great that no amount of effort can move the gear. It is more likely that the window handle will be broken.
...opening power windows. Busted Though more powerful, power windows still cannot overcome the pressure differential.
Contrary to popular belief, though, power windows can withstand immersion in fresh water for prolonged periods and still function. The electricity does not short out immediately.
...attempting to break the window using a set of keys. Busted Window glass is tempered and resistant to impact from blunt objects. Keys are ineffective.
...attempting to break the window using a cell phone. Busted A cell phone is ineffective.
...attempting to break the window using steel-toed boots. Busted Boots are ineffective.
...attempting to break the window using a window-breaking hammer. Confirmed The device is designed with a pointed tip designed to shatter tempered glass. The hammer broke the window on the first try.
...attempting to break the window using a spring-loaded center punch. Confirmed The point of the punch can work like the tip of the hammer, and punches are sold for the purpose of breaking window glass. The punch broke the window on the first try.

Seven Folds

Myth statement Status Notes
A dry piece of paper cannot be folded in perpendicular halves more than seven times, regardless of its size. Partly Busted It was impossible to fold a piece of letter-sized (8.5" × 11", 216 mm × 279 mm) 20 lb (75 g/m²) copy paper with perpendicular folds more than seven times. The thickness of the paper grew geometrically with each successive fold, and after the seventh fold the paper was just too thick to fold without breaking. Breaking the rules of the challenge, Grant showed that folding a particularly thin sheet of paper in the same direction 4 times then 4 times the other way, it is possible to fold the paper 8 times. The MythBusters then laid out a football field-sized sheet of interconnected paper (170 × 220 ft (52 × 67 m)), and due to the reduction of its area-to-thickness ratio (and with help from a steam roller and a forklift), were able to perpendicularly fold the paper 11 times. Other methods of folding a piece of paper (such as with alternating folds) proved able to break the fold threshold of 7 for letter-sized paper, and perpendicular folds of more than 7 are theoretically possible with thinner paper.

Episode 73 – "Speed Cameras"

  • Original airdate: March 7, 2007

Speed Cameras

The MythBusters tested whether a speed camera...

Myth statement Status Notes
...cannot see through a crystallized plate cover. Busted The crystals inside the cover did not reflect enough light to cause overexposure and fool the camera. Also, the legality of such a device was questioned.
...cannot see through a lenticular lens plate cover. Busted While designed to distort the plate from an angle, all or most of the letters of the plate were still identifiable in the tests. Also, the legality of such a device was questioned.
...cannot see through plastic wrap Busted The plastic wrap proved to be ineffective.
...cannot see through hair spray. Busted The hair spray was ineffective.
...cannot see through commercial distortion spray. Busted The commercial spray was ineffective.
...cannot take a picture of a car if it is going fast enough. Busted Neither a Dodge Neon nor a Lamborghini Murciélago were able to travel fast enough (at 138 miles per hour (222 km/h)) to outrun the camera.
  • However, the British motoring show Top Gear was able to beat the cameras by speed with a TVR Tuscan S[2] at 170 miles per hour (270 km/h), albeit with a UK-spec Gatso speed camera. This myth was revisited in season 5, wherein it was explained that while speed cameras in the UK require two consecutive photographs for a conviction, US speed cameras require only one. As part of the revisit, the MythBusters were able to beat the camera using a jet-powered car traveling at 245 miles per hour (394 km/h).
...can take a picture of a passing bird. Confirmed The speed camera managed to catch a pair of trained peregrine falcons passing it at a speed of 40 miles per hour (64 km/h).

The unofficial (Jamie Hyneman) test...

Myth statement Status Notes
A speed camera can be fooled if the license plate is switched while driving. Busted (unofficial) Rigging the license plate to flip before the camera shot allowed an inaccurate display of the real plate. However, this method is illegal and would most likely net a far greater fine than the speeding ticket itself, rendering the point moot.

Exploding Nitro Patches

Nitroglycerin is useful in treating heart and blood conditions, but is also an unstable explosive. The MythBusters test the efficacy of labels warning not to use a defibrillator before removing any nitroglycerin patches.

Myth statement Status Notes
Defibrillators can cause medical nitroglycerin chest patches to explode. Busted Using a homemade defibrillator, the build team attempted to see whether the electric shock it created was enough to cause the nitroglycerin in the patches to explode. However, the defibrillator failed to detonate the patches, including reproductions of older model aluminum-backed patches, as well pure nitroglycerin dabbed directly to the body. The build team was forced to use custom made, high power explosives in order to blow up the body.

Episode 74 – "Dog Myths"

  • Original airdate: March 14, 2007

Old Dogs, New Tricks

Following the old saying, Jamie and Adam see if they can teach an old dog new tricks.

Myth statement Status Notes
You can't teach old dogs new tricks. Busted With the help of professional dog trainers, Adam and Jamie were both able to teach two old dogs (Bobo & Cece, a pair of 7-year-old brother & sister Alaskan Malamute) sitting, heeling, staying, shaking hands, and lying down. However, Cece was the more obedient of the two dogs as Bobo had trouble staying.

Beat the Guard Dog

The Build Team tries to distract and get around a guard dog (in this case, a German Shepherd named Eewan) by...

Myth statement Status Notes
...distracting it with a steak Plausible The guard dog was distracted by smelling and eating the steak long enough for the intruder to reach her goal. However, once the dog was finished, it attacked the intruder.
...acting submissive Busted The intruder crawled on his hands and knees, but the dog attacked without hesitation.
...acting aggressive Busted The intruder yelled and waved his arms, but the dog attacked without hesitation.
...using the scent of a lactating bitch Busted The scent was sprayed on the intruder, but the dog attacked without delay.
...using the scent of wolf urine Plausible Initially, the dog did not attack, but instead sniffed the intruder. Eventually, it did attack before the intruder could move very far. Grant theorized that if someone covered themselves in wolf urine, they may survive (if they can tolerate the smell).
...using the urine of a bitch in heat Confirmed The scent was put on a cloth and dragged along the ground of the fence. The dog followed and licked the scent while the intruder sneaked in, reached the goal, and returned safely.

Afterwards, the build team tried to invent ways to get past Eewan.

Task Status Notes
Grant built a remote controlled cat puppet and drove it around the yard Failed The guard dog was initially distracted; however, because of bad controlling, the decoy and the thief crossed paths and eventually caused the guard dog to turn its attention to the intruder.
Tory crawled along inside a barrel with wheels Failed The dog first tried digging for the intruder, but eventually figured out how to grab one of the wheels for leverage and get at Tory. The experiment was stopped before there was any risk of injury.
Kari built a human-sized hamster ball covered in plastic wrap Partially Successful Kari was able to roll her way to the goal and back, but she was not able to get out of the ball without the dog attacking her.

Overall, while a few methods managed to work, the guard dogs can be specifically trained to ignore certain distractions. Thus, overall, this myth was considered only plausible.

Fool the Bloodhound

The MythBusters see what it takes to shake a scent hound.

A Bloodhound can be deterred by...

Myth statement Status Notes
...zig-zagging and doubling back. Busted Within minutes, the dog found Adam's scent.
...running through water Busted The dog found Adam as well, and water can even help the dog find people.
...covering the floor with pepper Busted The dog went to the area covered with pepper for a little while, before going back to Adam. old clothes and changing into new ones Busted The dog found Adam, but only after being distracted by the concentrated smell where the clothes were cleaned.
...covering oneself with cologne/coffee. Busted Both the cologne and coffee were ineffective.
...making an urban maze with many more smells. Plausible Unlike the other runs, Morgan the Bloodhound was confused by the other smells around him. His trainer had to take him back to the start and try again. The dog only found Adam after 90 minutes of wandering around, and had taken a different path than Adam. The reason is that Morgan had not yet been trained to deal with urban tracking. However, there are bloodhounds that are specifically trained to work in urban environments, and the MythBusters pointed out various recorded instances of scent dogs successfully tracking targets in dense urban areas.

Episode 75 – "Myths Redux"

  • Original airdate: March 21, 2007

This is the sixth episode in which earlier myths are retested.

The Mad Trombonist

Myth statement Status Notes
A trombonist had put a firecracker into his mute, and at the final note of the 1812 Overture, launched the mute, striking the conductor and knocking him back into the audience. In addition, the bell of the trombone was blown wide open and the slide was launched (From The Mad Trombonist). Re-Busted The re-test involved placing simulated lips against the trombone's mouthpiece so as to seal that end. This still failed to cause the slide to fly off the instrument. They only achieved the feat by soldering a plug into the mouthpiece, completely sealing it shut; the tuning slide was blown backwards out of the trombone as well.

Sniper Scope

Myth statement Status Notes
A sniper can kill another sniper by shooting straight through the scope. (From Firearms Folklore) Plausible Using a period-correct Mosin-Nagant PU scope (which has less glass) and a .30-06 armor piercing round, Jamie's shot went completely through the sight and penetrated two inches into the target dummy—deep enough to be a possibly lethal hit. Shots with standard ball ammunition produced less successful results.

Finger in a Barrel

Myth statement Status Notes
A shotgun plugged by a human finger will backfire and explode injuring or killing the shooter instead of the intended victim. (From Finger in a Barrel) Re-Busted The re-test used a 19th-century double-barreled shotgun made through Damascus welding. The first barrel was damaged by a ballistic gelatin finger, though not as seen in cartoons. A steel finger welded to the end of the second barrel simply made the whole tip of the barrel shoot off.
A .30-06 rifle fired while having a boresight still in the barrel will backfire and explode, creating a cartoon-like banana peel effect as shown in submitted photographs. (Spinoff from Finger in a Barrel) Plausible The Build Team's test used a brand new rifle. The barrel split several inches when fired with a laser boresight in the barrel. The Build Team surmises that the banana-peel effect could be achieved if this were to happen in an older rifle that has endured more wear and tear from firings.

Hammer vs. Hammer

Myth statement Status Notes
If two hammers strike each other, at least one hammer will completely shatter with lethal force. (From Hammer vs. Hammer) Re-Busted First, the Build Team properly heated two modern hammers to the transition point and quenched them, making them as brittle as possible. The two hammers simply snapped at the necks when struck. Then they tested older steel hammers (predating World War II). Though the heads began to chip when struck, one of them ultimately snapped at the neck as well.
If a hammer strikes hard against an anvil, the hammer will completely shatter with lethal force. (From Hammer vs. Hammer) Re-Busted For this re-test, they used a genuine steel anvil and used a rig that would make the hammer strike against the top of the anvil. The pre-WW2 steel hammer suffered cracks and chips from first a human-strength then a superhuman strike, but it did not shatter.

Episode 76 – "Voice Flame Extinguisher"

  • Original airdate: April 11, 2007

Voice Flame Extinguisher

Myth statement Status Notes
An unamplified human voice can put out a fire. Busted It proved to be impossible for an unamplified voice to extinguish a candle; however, a singer in a local group was able to put the candle out through amplification.
Sound alone can put out a fire. Confirmed A pure, amplified tone was able to put out a well-sized fire. This can be done because the pressure waves from the sound disrupt the air enough to snuff out the flame. Also, using a high explosive bomb can put out flames since the blast wave pushes away the oxygen that fuels the fire, or the explosives use up so much oxygen so quickly, that the fire cannot sustain itself. Oil well firefighters commonly use explosives to put out oil well fires.


Myth statement Status Notes
Using hypnosis can make one go against their will. Busted While hypnotized, Grant was told to do certain uncharacteristic actions through hypnotic suggestion, and he would perform these actions after a specific trigger. However, the triggers did not work (possibly because Grant knew he was being given a trigger, even if he did not know what it was), so the test was performed again on a producer who believed in hypnosis (this time trying to slip the triggers in during an otherwise clandestine hypnosis session). However, this test also failed. In addition, many experts and hypnotists agree that hypnotic suggestion will never work if the suggestion conflicts with the subject's moral fiber. Note that this verdict is in contrast to an earlier myth on hypnosis as a form of remote mind control.
Using hypnosis can make one remember things more clearly. Confirmed The Build Team was given a short play (involving Jamie and local actors playing deliverymen) and were later quizzed about minor events, in which they failed miserably. Taking the same tests under hypnosis, they remembered tiny facts such as name tags and tattoos and achieved a better score.

Episode 77 – "Birds in a Truck"

  • Original airdate: April 18, 2007

Birds in a Truck

Myth statement Status Notes
Birds flying around inside a truck will actually make the truck lighter. Busted Adam and Jamie constructed a large box and placed it on top of scale and then filled it with captured pigeons. Then, the MythBusters activated a special contraption that would force the pigeons to fly into the air, but they could not detect any discernible difference in the weight of the box. They then placed a model helicopter inside the box and had it hover above the ground, but this method also failed to produce any results. The MythBusters theorized that the air being displaced by the birds' wings and the helicopter rotors was pressing down the box, which is why there was no change in the overall weight. All was in compliance with Newton's third law of motion.

Bifurcated Boat

Myth statement Status Notes
A boat moving at 25 miles per hour can be split down the middle by hitting a channel marker. Busted Through small scale tests, the build team noticed that whenever they tried to have their model boat hit the channel marker dead on, the boat would just glance off with minimal damage. Tory then tried having the boat turn into the marker at the last second, which produced more positive results. Moving on to full scale, the build team acquired a used boat (dubbed the Mythity Split) and had it crash into a specially constructed channel marker. The Mythity Split struck the marker, but only suffered minimal damage rather than splitting. The build team then tried moving the boat at faster speeds, but still could not split the boat (The team did acknowledge the split would be possible at a very fast speed, but not the mythical 25 mph/40 km/h). Wanting the boat to be completely destroyed, the build team opted to drop it from a crane, effectively busting the myth in the process (and damaging the crane when the boat toppled over onto it).

Episode 78 – "Ninja Myths"

  • Original airdate: April 25, 2007

The MythBusters test various Ninja-related myths.

Walking on Water

Myth statement Status Notes
Ninjas had the ability to run across water. Busted To test this myth, Adam tried various special shoe designs, including Mizu gumo, which were meant to increase his surface area on the water or increase his buoyancy. However, the shoes either failed to keep Adam afloat or were impossible to control as he tried to cross the body of water. Jamie then created a Non-Newtonian fluid from a mixture of water and corn starch, which made the water solid enough for Adam to run across unaided. However, it is unlikely that ninjas had access to large amounts of corn starch (if any at all), so the myth was busted.

Catching an Arrow

Myth statement Status Notes
Ninjas can catch arrows in midair. Busted To start off, Jamie fired arrows blunted with tennis balls while Adam tried to catch them. Though it took several tries, Adam did manage to catch the arrows flying through the air. However, these arrows were only moving at a third of the speed of a normal arrow. In order to test a full speed arrow, Adam and Jamie built an artificial hand that could close with both human and superhuman speed. The artificial hand managed to catch the arrow easily in superhuman speed, but the human strength setting was just not powerful enough to grip the arrow in time.

Catching a Sword

Myth statement Status Notes
Ninjas can catch a sword in between their bare palms. Busted To test this myth, the build team constructed a machine to swing a sword as well as a pair of artificial hands to try to catch it. However, during their tests, the hands were simply not fast enough to catch the sword, plus they suffered damage as they attempted to stop the blade. When they consulted an expert, he pointed out that it would be more prudent to either block or dodge the sword rather than trying to catch it with one's bare palms. He did show that with the use of Ninja Shuko Climbing Claws he could easily block a sword with a single hand.

Episode 79 - Western Myths

  • original airdate: May 30, 2007

Shooting a Hat

Myth statement Status Notes
A cowboy can shoot a hat off a person's head, sending the hat flying through the air without harming the wearer. Busted Using an arsenal of period weapons, cowboy hats, and a dummy head, Adam and Jamie were unable get the hat to fall off the dummy's head, much less fly. The bullets simply could not transfer enough force into the hat to make it fly off. While pistols and rifles were ineffective, the MythBusters found that shotgun shells could make a hat fly into the air since the birdshot provided greater surface area to transfer the force of the shell. However, the birdshot also peppered the dummy in a fashion that would be fatal to a human being.

Lockpick of Death

Myth statement Status Notes
A thief attempted to pick the lock of a car and accidentally tripped the side airbag, launching the lockpick with enough force to skewer his skull. Busted The Build Team constructed a robotic arm to simulate a person attempting to pick the lock of a car. They then placed a ballistics gel head over the arm to simulate a human head. However, they were unable to trigger the side airbag with the lockpick (the mechanic present explained that the airbag was not inside the door but in the car and attached to the inside of the door). The Build team then built a robotic leg, under the assumption that if the thief was unable to break into the car, he would kick the car in frustration and trigger the side airbag. Neither a human nor superhuman strength kick could trigger the airbag. Plus, the airbag is placed in a way that it would never be pointing towards the lockpick, meaning that it could never be launched. In order to replicate the results, the Build Team encased the lockpick in a sabot and placed it inside an air cannon. The lockpick, fired from the cannon, was able to skewer the skull. However, there was no clear evidence to suggest that the myth was in any way true.

Old Western Jailbreak

Myth statement Status Notes
A horse can be used to pull the bars out of a prison window and help free the occupant inside. Busted After some research, Adam and Jamie built a replica of a period prison cell (based on one in Fort Dodge, Kansas built out of railroad ties), complete with a barred window. However, when they tied a horse to the bars and attempted the pull them out, the bars did not budge. Two horses could not pull out the bars and neither could a motorized cart that was twice as strong as both horses combined. As a last ditch attempt, the MythBusters tried pulling the bars out using a 30,000-pound (14,000 kg) crane. However, the steel beams bracing the wall failed before the prison bars did. Since not even a modern vehicle could pull the bars out of the window, it is unlikely that any number of horses could.
A prisoner can be freed from an Old West jail cell with a single stick of dynamite. Busted The MythBusters placed a single stick of dynamite on the cell window and detonated it, with Buster inside to test whether the occupant would survive. While the dynamite did not cause any significant damage to the wall, it did loosen the bars enough for Adam to pull them out and escape. However, the blast set off all of the shock pads on Buster, indicating that even though a single stick of dynamite exploding would allow him to escape, the shock of the blast would kill him first, busting the myth. Jamie remarked that an axe could achieve the same amount of damage the dynamite caused, with significantly less noise.

Lone Ranger's Silver Bullets

Myth statement Status Notes
The silver bullets used by the Lone Ranger are more effective than standard lead bullets. Busted This myth is seen on Discovery's website, and was part of Adam's own curiosity of why the Lone Ranger used silver bullets instead of normal lead ones. As a test, he hand-crafted a silver bullet, fired both it and a lead bullet into ballistic gel. The lead bullet penetrated farther than the silver bullet due to its greater density and mass, and thus is more effective in bringing down an opponent. Also, silver shrinks when cooled, forcing precision accuracy when forging bullets out of it, and was used as a form of currency back in the Wild West, which would make using silver bullets impractical and a waste of good money.

Episode 80 - Big Rig Myths

  • Original airdate: June 6, 2007

This was the first episode in which all myths shown on television (excluding the special website-only myth, which was Plausible) were confirmed.

Exploding Tire of Death

Myth statement Status Notes
A tire on a big rig can explode with lethal force. Confirmed The MythBusters first tested whether a big rig tire could actually explode. They managed to obtain several truck tires and subjected them to actual road conditions, to try to replicate certain circumstances that could cause a tire to explode. Although they could not make a tire fail catastrophically, they managed to cause it to disintegrate violently by running the tire flat at highway speed, though the flying debris failed to hit the dummy set up next to the tire. However, the MythBusters were able to measure the velocity of the debris. Taking an actual piece of the exploded tire, the MythBusters launched it at its measured initial velocity into a pig spine-equipped ballistics gel dummy behind a car window. The piece of debris smashed through the window and literally decapitated the dummy, proving the myth was in fact possible.

Drafting For Money

Myth statement Status Notes
Drafting, or slipstreaming, behind a big rig will improve a car's fuel efficiency. Confirmed To test this myth, the build team procured a car, a big rig, and a device that could measure a car's fuel efficiency. They then drove the car behind a moving big rig at various distances ranging from 100 to 2 feet (30 to 0.61 m) and measured the amount of fuel the car consumed. The Build Team discovered that the closer the car was to the big rig, the less drag is produced, thus the more fuel saved. At just 10 feet (3.0 m), the car managed to increase its fuel efficiency by 40%. Drafting at 2 feet (0.61 m) was slightly lower than the ten-foot distance, mainly because Grant had to keep working the car pedal to maintain distance from the truck. However, that did not dispute the fact that drafting actually can increase a car's fuel efficiency if a constant velocity is kept. However, the Build Team has warned that drafting is incredibly dangerous because the truck driver may not be able to see cars that are that close, and the driver of the car may not be able to react in time if the truck were to make a sudden stop (they noted that at two feet, a person has less time to act than it takes to blink).
Scale wind tunnel test: drag
reduction from baseline at 50 mph (80 km/h):
seven car lengths 10 ft (3 m) 6 ft (2 m) 2 ft (1 m)
21% 60% 80% 93%
Controlled road test: fuel consumption
decrease from baseline at 55 mph (89 km/h):
100 ft (30 m) 50 ft (15 m) 20 ft (6 m) 10 ft (3 m) 2 ft (1 m)
11% 20% 27% 39% 28%

Knight Rider Ramp

Myth statement Status Notes
As seen in the TV series Knight Rider, a moving car can safely transition from a road into a moving big rig via ramp. Confirmed To test this myth, the MythBusters first started with a small scale test using a toy car. Simulating the Knight Rider stunt, the MythBusters found that the toy car could enter the big rig safely without a sudden and dangerous acceleration that many people had feared. They then tested the stunt at full scale using a Chevy Camaro, which is similar to a Pontiac Trans Am like the one used in Knight Rider. They tested at both 30 mph (48 km/h) and 55 mph (89 km/h) with no difficulty. The MythBusters explained that, even when hitting the truck's ramp, the car's inertia keeps it going at exactly the same speed relative to the ground—which lets it safely drive into the big rig, with no surprising accelerations. Jamie then reinforced the myth by safely exiting the moving semi truck in reverse.

Cyclists Drafting a Big Rig

Myth statement Status Notes
Cyclists can draft behind a big rig and achieve "crazy speeds". Plausible Seen on the Discovery Channel's website, the Build Team decided to test whether a cyclist would have an easier time riding if he were to draft a big rig. Tory was chosen as the cyclist and performed a control test by cycling up to 20 miles per hour unaided. To ensure accuracy, Grant kept track of Tory's heart rate and Kari measured his speed via radar. By the end of the control run, Tory was exhausted by the effort. During the actual test, however, Tory literally coasted along behind the big rig and rarely had to pedal at all. Due to the obvious difference in performance and the fact that professional cyclists draft (behind each other) during competitions, the myth was plausible. But it is unsafe: do not do it.

Episode 81 - Grenades and Guts

  • Original airdate: June 13, 2007

Self Hypnosis

The Build Team tested whether self-hypnosis could...

Myth statement Status Notes
...cure seasickness. Busted Grant, who is susceptible to seasickness, volunteered to test self-hypnosis to see whether he could overcome his condition. As a control, he was put into a chair that helped induce seasickness while Tory and Kari kept track of how long it would take for him to vomit. Grant then used a self-hypnosis CD to try to cure his sickness. After his self-hypnosis session, Grant went back to the chair, but still succumbed to his sickness, although it took twice as long.
...change eye color. Busted Kari first went to an eye center to obtain a control photo of her eye color. She then underwent a self-hypnosis session in an attempt to change her physical eye color. However, when she went back to the eye center to have her eyes analyzed, the results showed that there was no change in eye color.
...eliminate a person's fear of bees. Busted Because Tory had no real issues that could be resolved through self-hypnosis, the Build Team instead brought Adam and tried to cure him of his irrational fear of bees. For the control test, they measured Adam's heart rate and physical stress levels when he was shown a box full of bees and had to put his hand inside of it. After going through his self-hypnosis session, Adam retook the test. During the retest, Adam showed the same amounts of fear and physical stress as the control test (and swearing), showing that he still possessed his fear.

Even though the Build Team only tested self-hypnosis in several specific cases, because of the results, they deemed that the overall myth of self-hypnosis was busted.

Diet Coke & Mentos II: Exploding Stomach

Myth statement Status Notes
If a person swallowed both Mentos and Diet Coke, his stomach would explode. Busted This myth is based on an internet video where a man ingested both Diet Coke and Mentos and fell unconscious, reportedly from a ruptured stomach. When tested with a pig's stomach, it was learned that the simple act of drinking the soda released much of the carbon dioxide within it, preventing the expected cascade of foam the Mentos and soda combination would give off. Even pumping the gas from the normal Mentos/cola fountain directly into the stomach did not make the stomach burst, but like the previous myth of soda and Pop Rocks, the stomach expanded to the point where the victim would be in a lot of pain and induced vomiting. Only by blowing compressed air directly into the stomach did it burst.

Hand Grenade Hero

This myth was based on various Hollywood depictions of how heroes would dispose of grenades in order to save their comrades. The MythBusters tested whether a hero could save his buddies by...

Myth statement Status Notes
...covering the grenade with his own body. Confirmed During the control test, the MythBusters detonated a grenade with no obstacles with several plywood dummies around it at varying distances. The shrapnel inflicted lethal injuries on most of the dummies. For the actual test, the MythBusters planted a ballistics gel dummy over the grenade before detonating it. While the ballistics gel dummy was completely destroyed, only one of the plywood dummies suffered any severe damage, and what damage was caused was not lethal. While the hero would undoubtedly die in the attempt, he would be able to save his comrades nearby, as also described in dozens of Medal of Honor citations.
...placing the grenade in a bucket full of water. Confirmed The MythBusters placed a grenade in a bucket full of water, in hopes that the bucket would slow down the shrapnel enough to inflict no harm on the plywood dummies. However, there were fears that the bucket would in fact contribute to the damage by being turned into shrapnel itself. After the test, only one of the dummies suffered lethal damage, but there was still significantly less shrapnel damage than the control test. Though not perfect, one advantage to this method is that the hero does not have to sacrifice himself.
...throwing the grenade inside a refrigerator. This particular myth was based on a scene in Monk episode "Mr. Monk and the Election". Busted The MythBusters obtained a refrigerator and placed it in the middle of a group of the dummies. They then placed a grenade inside it and detonated it. The refrigerator was literally turned into a giant fragmentation grenade as also happened in the original episode. Unlike the episode, however, where the fridge absorbed the explosive force enough to leave bystanders unharmed, the flying debris from the Mythbusters' test destroyed the dummies immediately in front and behind of the refrigerator, though standing to the sides seemed safe. The MythBusters agreed that putting a grenade in the refrigerator was not a good idea.

Before the above experiments, Adam tested a mini myth:

Myth statement Status Notes
It is possible to pull the pin out of a grenade using one's teeth. Busted Adam tried it and failed. It takes 10 pounds-force (44 N) to pull the pin by hand, enough force to either break or uproot teeth.

Episode 82 - "Snow Special"

  • Original airdate: June 20, 2007

The following myths state that an avalanche can be caused by...

Myth statement Status Notes
...yodeling. Busted While the small-scale experiments indicated that aimed at the right place, an amplified voice can set off an avalanche, in the final test, no amount of yodeling by a professional yodeler could elicit a response. The yodeler was provided with a megaphone, but again, no avalanche took place.
...a whip crack. Busted Adam theorized that the miniature sonic boom caused by the cracking of a whip could trigger an avalanche, however, no avalanche took place.
...submachine gun fire. Busted This myth was started with stories of World War I soldiers setting off avalanches in heavily snowed-in areas with their artillery, thus using them as environmental weapons. Adam and Jamie attempted to test if lower-powered weapons, such as machine guns, could also cause an avalanche. They tested this with a pair of MP5s, though they could not cause an avalanche to start.

Despite the "busted" designation, Jamie emphasized that avalanches are "finicky beasts" and cases of skiers unintentionally setting them off have been noted. Therefore, it is impossible to tell exactly what will trigger an avalanche.

Myth statement Status Notes
A person's tongue can instantly stick to a freezing (below 32°F) metal pole when touched, making it difficult to remove. Confirmed This is the classic "triple dog dare" stunt (from A Christmas Story). Using both Tory's tongue and a pig's, it was determined that a standard human tongue can be frozen to a cold metal pole substantially enough to risk pulling some of the skin and muscle off of the tongue. Kari jokingly suggested that a person could free themselves by peeing on the contact point between pole and tongue.
Driving backwards on an icy road will give the car better traction than driving forwards Busted While it was determined that drivers get better traction on an icy road while driving in reverse, when put into practice, the increased traction did not offset the sheer difficulty of driving in reverse. The Build Team theorized that because driving backwards is so difficult by itself, the ice compounded that difficulty, rendering any additional traction useless.

Episode 83 – "Baseball Myths"

This episode featured Roger Clemens as a guest star in a short segment explaining the physics behind different pitches.

  • Original airdate: August 8, 2007

Corked Bat

Myth statement Status Notes
A baseball bat filled with cork can hit a baseball farther than a normal bat. Busted This myth operates under the assumption that cork-filled bats can be swung faster because of their lighter weight, and that the springiness of the cork could propel the ball farther. To eliminate the human factor of the myth, Adam and Jamie constructed a special batting rig and used a pressurized air cannon to launch the baseball at it. Tests showed that the cannon could launch the ball 80 miles per hour, which is the average speed of most MLB pitches. Regulation bats could propel the ball away at 80 mph (130 km/h) while corked bats could only propel the ball 40 mph (64 km/h), half the speed of regulation bats. The reason was that cork bats have less mass to transfer force into the ball, and the cork actually absorbs some of the ball's impact. The MythBusters concluded that using a cork filled bat will not improve performance (it will in fact hurt it), and the major league batters who were caught using cork-filled bats risked their careers for absolutely nothing.

Humid Balls

Myth statement Status Notes
A dry baseball can be hit farther than a ball stored in a humid environment, which is why baseball teams that store their balls in humid environments suffer from lower home run averages. Plausible The Build Team started off with a small scale test by dropping dry and humid balls from a certain height. The results showed that the dry balls tended to bounce higher than the humid balls. For the full scale test, Grant built his own rig (dubbed "The Mad Batter") that could both swing the bat and pitch the ball at the same time. They then tested the rig at a baseball field using humid balls, dry balls, and control balls stored in a normal environment. The results showed definitively that the dry balls were hit the farthest distance and the humid balls being hit the least distance. The Build Team agreed that outside forces may be at work, but the data supported the myth enough to be considered plausible.

Rising Fastball

Myth statement Status Notes
A fastball (pitched overhand) can lift itself higher into the air. Busted Despite the testimony of some pitchers, the myth would defy the laws of physics because in order for a fast ball to actually rise, it must exert more force upward than its own weight. However, the maximum force a fast ball can exert is only half of its weight, making a rising fast ball impossible. When compared to a "non-rising" fast ball, the baseball does not drop as much as it normally would, giving it the optical illusion of appearing to have risen.

The Slide

Myth statement Status Notes
On bases that a player can't overrun, it is faster to slide into them. Confirmed While a popular tactic used by baseball players, some speculate that sliding will actually slow a person down due to the friction being exerted between their bodies and the ground. With some coaching, the Build Team learned how to slide like baseball players. They then timed how long it would take to run to a base and slide to a base. The results showed that the entire Team — Tory, Jamie, and Grant — reached the base faster by sliding than by running, by a fraction of a second, supporting the explanation that as they ran, Tory, Jamie, and Grant had to slow down at the last second so that their momentum would not carry them past the base. With such definitive results, the MythBusters agreed that sliding to a base is faster than running.

Hitting the Hide Off a Ball

Myth statement Status Notes
A baseball's stitches can tear and the hide of the baseball will fall off if the baseball is thrown fast enough and hit hard enough. Busted The MythBusters modified their cork bat rig to fire the baseball at much higher speeds. It fired the ball at a static bat with speeds over 200 mph (320 km/h), which is twice as fast as the fastest pitch ever recorded, which broke the bat. However, the ball remained intact. The MythBusters then fired the cannon at maximum power. The hide of the ball did come off, but the ball was fired at a metal pole (which is much harder than wood) at 437 mph (703 km/h), four times faster than, and with 17 times the energy, any human could pitch.

Episode 84 – "Viewer's Special"

  • Original airdate: August 15, 2007

Viewers will pick myths they think need to be tested and the MythBusters will pick the best to test.

Myth statement Status Notes
If a person sneezes with his or her eyes open, their eyes will fly out from the force. Busted It was hard for Adam and Jamie to sneeze with their eyes open, but Adam eventually did the trick by forcing his eyelids open with his fingers. His eyes were fully intact. It would be impossible for a person's eyes to pop out because of the number of natural attachments that keep the eye inside the socket.
A runaway car can be stopped by shifting the gears into reverse. Busted Using both an automatic and a manual car, both cars were given the full force of the brake and stopped after 65 and 80 feet (20 and 24 m), respectively. Shifting into reverse did just about nothing, and both cars stopped after over 1,000 feet (300 m). The automatic car had a fail safe to prevent it from going into reverse while traveling forward. They also tested if an automatic car in park would have stopped it, it did not. Additionally, shifting into reverse or park at high speeds can damage the transmission of the car.
Firing cigarette butts out of a gun can hit with lethal force. Confirmed The MythBusters first fired cut-off cigarette ends, but none of them penetrated the ballistics gel mold, let alone into the heart. It was only after they fired at point-blank range and fired cigarette butts from used cigarettes, full of cigarette waste material, thus adding mass, that the heart was damaged.
By cutting a hole in a tennis ball, one can squeeze the ball and the resulting air pressure can unlock a car door. Busted The Build Team replicated an online viral video with two different tennis balls with two sized holes, but the car door did not unlock. They blasted the lock with full air pressure, but it still did not do anything. They finally recreated the events in video by having Tory unlocking the door remotely in the background, and were quick to point out that clever editing can make things look real.

The Build Team also tested if one could prevent an opponent's sword from piercing the chest with...

Myth statement Status Notes
...a hardcover Bible. Confirmed Since the MythBusters chose not to use a real Bible, a hardcover book (the pocket reference of the MythBusters) was used, and was able to prevent a sword being thrust at human strength and speed from piercing the pig's flesh.
...a bunch of coins. Busted The coins merely deflected the blow to another part of the body.

The MythBusters also demonstrated the difference between a "Hollywood" explosion, using gasoline; and an explosion using actual explosives, on a car donated by a 12 year old fan, who requested that the MythBusters "blow up my parents' car."

Episode 85 – "Red Flag to a Bull"

  • Original airdate: August 22, 2007

Hot Bullets

Myth statement Status Notes
An oven door can stop bullets. Busted The oven door failed to stop .38 caliber rounds, .357 magnum rounds, and shotgun shells. The only exception was that the .22 caliber pistol rounds were unable to pierce the steel part of the oven door.
Bullets can explode with lethal force if they are stored inside a hot oven. Busted The MythBusters placed a .22 caliber, .44 caliber, and .50 caliber bullet inside an oven. All of the bullets exploded once the oven was hot enough, but none of them were able to penetrate the oven. Without a gun barrel to contain and direct the propellant gases, the bullets did not develop enough speed to pierce the glass or steel portions of the oven. The cartridge casings actually caused more damage than the bullets.
A gun can fire a bullet with lethal force if stored inside a hot oven. Confirmed The MythBusters placed a loaded .38 caliber revolver inside a hot oven pointing towards the oven door. Once the temperature was high enough, the gun spontaneously discharged and sent the bullet out of the oven, which could possibly kill anybody who happened to be standing in front of the oven.
Bullets thrown into an open fire can explode with lethal force. Busted The MythBusters dropped a box of bullets with varying calibers directly into an open fire. While many of the bullets immediately discharged, it appeared that none of the bullets could be lethal. Like the oven test, most of the damage was being dealt by the cartridge casings, which could not travel fast enough to be lethal. However, they determined that the bullets could cause many non-lethal injuries.
Aerosol cans placed in an open fire can explode with lethal force. Busted While the aerosol cans exploded rather violently, the worst damage they could do was cause burns.
A beer keg can explode with lethal force if placed in an open fire. Plausible Getting the keg into the fire proved to be difficult at first as the full keg was too heavy. Adam figured that once the keg was light enough, (and everyone in the party drunk enough) the keg could be tossed in. While the beer keg exploded violently, there was no shrapnel from the explosion. However, the MythBusters pointed out that any shrapnel thrown from such a powerful blast could kill a person. Jamie also joked that it would be a waste of beer.
A fire extinguisher will explode with lethal force if placed in a fire. This myth is shown only in the Discovery website. Busted Even though fire extinguishers are capable of killing a person if the cylinder is punctured, they will not explode when put in a fire due to a built in safety feature. Newer extinguishers have a release valve which blows out if the cylinder's pressure limit is exceeded. After a while in the fire the release valve was triggered by increased pressure and the carbon dioxide was released safely.

Red Flag to a Bull

Myth statement Status Notes
The color red can infuriate a bull and make them charge. Busted To test this myth without putting themselves in danger, the Build Team constructed three fake matadors that would carry differently colored flags. First, they placed stationary flags of different colors near a bull. The bull charged the red, white, and blue flags with equal ferocity, even when all three flags were out at once. Using a remote controlled clothes line, the Build Team managed to prove that the bulls were angered by movement rather than color. They then placed the matador dummies in the ring, each one dressed in a different color. The bull charged the white dummy first, the blue dummy second, and the red dummy last. Finally, Tory went into the ring dressed in a red jumpsuit and had to stay still while two professional cowboys moved around the ring to try to draw the bull's attention. The bull chased the cowboys for a short time, but ignored Tory, which proved the theory that bulls concentrated on movement more than color.

Bull in a China Shop

Myth statement Status Notes
The idiom "bull in a china shop" is accurate. Busted The Build Team placed shelves full of china inside a bull pen and released bulls inside it. Surprisingly, the bulls went out of their way to avoid the shelves, even when there were multiple bulls inside the pen at the same time. A single shelf was knocked over by accident by the first bull released in the pen, and a few dishes were knocked to the ground when as many as four bulls were running around, but overall the bulls proved surprisingly nimble. A representative from the National Rodeo Association later corroborated the results, explaining that bulls seldom move when placed in tight confinement like pens and trailers.

Episode 86 – "Superhero Hour"

  • Original airdate: August 29, 2007

Grappling Hook

Myth statement Status Notes
Superheroes can use grappling hooks to quickly scale walls. Grappling gun Busted, Handheld winch Plausible To begin, Adam used a plain grappling hook and rope while Jamie had a special cannon that could shoot the hook 100 feet (30 m) in the air. While it took several tries for Adam to throw the grappling hook over a 20-foot (6.1 m) wall and gain purchase, Jamie managed to accomplish this task in one shot. They then attempted to scale the wall, but found that scaling a wall with just a grappling hook and rope was too difficult and time consuming. Adam and Jamie then began working on different parts of the popular grappling hook gadgets. Adam would build the gun that would deliver the grappling hook into the wall, while Jamie would build the winch that would allow the superhero to actually scale the wall. Jamie tested his handheld winch, which managed to pull him up 27 feet (8.2 m) in just 20 seconds. However he had to cut the line since he had neglected to add a reverse function as a way to get down. Adam then tested his gun, which took numerous tries to find purchase in the wall. When Adam attempted to swing from the line, it instantly failed. Even with such mixed results, the MythBusters agreed that a handheld grappling hook device was too implausible.

Ring Punch

Myth statement Status Notes
A superhero can punch a person so hard, he can leave a scar that matches the imprint on his ring. This myth was based on the comic book superhero The Phantom. Busted First, the Build Team measured the force of their punches, and compared them to the punching strength of professional fighters. Grant then constructed a punching robot that could replicate these forces. Meanwhile, Tory constructed a ballistics gel fist while Kari designed the rings out of sterling silver. For the target, the Build Team obtained a human skull and stretched pig skin over it to simulate human skin. Punching the head with Tory's level of strength caused some damage, but did not produce a ring-shaped scar. The professional fighter's level of strength produced similar results. The Build Team then used superhero level strength which crushed the skull. The Build Team concluded that a punch powerful enough to leave an imprint of their ring would most likely crush the victim's skull, and kill him. (Note: Throughout the portions of the episodes where they continually tested this myth, Tory mentions he may have broken his hand on the force gauge)

Phone Booth Quick Change

Myth statement Status Notes
A superhero can change into his or her costume while inside a phone booth. Confirmed The Build Team took turns removing their street clothes to reveal their superhero costumes while inside a phone booth. Kari was the fastest, changing in just 33 seconds while Tory was the slowest, taking over 1 and 1/2 minutes to change.

Vehicle Grappling Hook

Myth statement Status Notes
A car can fire a grappling hook and use it to make sharp turns at high speeds. Busted The Build Team converted the vehicle (Pontiac Trans Am) used in the earlier Knight Rider myth into a mock Batmobile dubbed the "Mythmobile". They then built a nitrogen powered cannon portable enough to fit in the car and powerful enough to launch the steel grappling hook. They then tested how fast a car would need to go to make a manual turn impossible, which was about 30 miles per hour (48 km/h). While they were able to hook the grappling hook around the target, the cable always snapped when the car attempted to make the turn. They concluded that, while the other aspects of the myth are plausible, no rope or cable currently exists that is strong enough to withstand the force.

Episode 87 – "Myth Revolution"

  • Original airdate: September 5, 2007

The MythBusters revisit several past myths with a special twist. This time, they are exploring several side myths that they had missed while testing the main myths.

Swatting a Bullet

Myth statement Status Notes
A modern ninja can slap a bullet out of the air. (From Catching an Arrow) Busted The Build Team first set up a small scale test by firing paintballs at Tory and seeing if he could slap the paintballs away. During the test, Tory proved that human reflexes were fast enough to slap away a paintball. They then constructed a rig that would mimic a human hand making a slapping motion and used it to try to slap bullets fired from a 9 mm handgun. The Build Team quickly discovered that human speed was nowhere near fast enough to slap the bullet so they powered up the rig to slap at superhuman speed. The hand managed to slap the bullet, but it was not powerful enough to significantly change the bullet's trajectory (it just cut the hand).

Thumbs Over the Airbag

Myth statement Status Notes
Drivers who hold the steering wheel in the 10-2 position can have their thumbs ripped off by a deploying airbag. (From Lockpick of Death) Busted The Build Team obtained steering wheels with working airbags and created a pair of ballistics gel hands that would simulate a driver holding the steering wheel at the 10-2 position. When the airbag deployed, it knocked the arms off of the steering wheel, but did not cause any visible damage to the thumbs. Then, based on a report of an actual thumb injury, the Build Team tested the myth with the driver's hands positioned in a fashion similar to the Vulcan Salute with the thumbs directly over the airbag. The deploying airbag caused serious damage to the thumbs, including breaks in the simulated bones. However, because the myth was based around the commonly used 10-2 position, the myth was busted.

Exploding RFID Tags

Myth statement Status Notes
An RFID tag will explode if placed inside an MRI. (From Exploding Tattoo) Busted The Build Team inserted an RFID tag into pig flesh and placed inside the MRI but failed to get any results. Kari then had an RFID tag placed inside her arm and was placed inside the MRI. The RFID tag remained unaffected and left Kari unharmed.

Breathing Through a Tire

Myth statement Status Notes
A person can stay underwater for an extended period of time by breathing the air from a car tire. (From Underwater Car) Busted Once again, Adam volunteered to sit inside a sinking car. Once the car sank, Adam exited the vehicle and cut a hole in the tire and attempted to breathe the air leaking from it. However, he could not breathe in enough air from the tire and was forced to breathe from an emergency air tank.

Beating the Speed Camera

Fans complained about inconsistencies in the first Speed Camera tests, which prompted the MythBusters to revisit the speed camera tests so that if a speed camera was 10 feet (3.0 m) from the ground, it can be beaten by...

Myth statement Status Notes
...a magnified cover. Re-Busted The magnified cover partially obscured the license plate from the higher-angle camera, but not enough to deter a ticket; only one character was obfuscated.
...a reflective cover. Re-Busted The reflective cover failed to obscure the license plate.
...commercial spray. Re-Busted The commercial spray failed to obscure the license plate.
...pure, raw, unadulterated speed Confirmed Acknowledging the success of "a car show in the UK" in beating the speed camera, the MythBusters obtained a race car dubbed "The Beast", which used a jet engine that could propel it speeds of up to 300 miles per hour (480 km/h). In the first run, The Beast hit 245 miles per hour (394 km/h) and managed to pass the camera so fast that it never took a picture. In the second run, the speed camera was slightly modified to account for the increased speed, but still failed to take a picture of The Beast, which traveled faster than the first run. Even though the speed camera was beaten, the MythBusters pointed out that only specialized cars like The Beast could achieve those kinds of speeds and would therefore be very easy to find by the authorities.

Snow Rescue

Myth statement Status Notes
A trained dog can rescue a person trapped in an avalanche. (From Snow Special) Confirmed This is only seen on the Discovery Channel's website. Adam was buried in a snow cave with 15 minutes of air and an emergency beacon. A trained dog was able to locate Adam with time to spare.

Episode 88 – "Trail Blazers"

  • Original airdate: October 31, 2007

Adam and Jamie get on the trail of some flammable Hollywood fables while Kari, Grant and Tory break out the defibrillator for some electrifying action.

Vapor Trail

Myth statement Status Notes
If the trail of gasoline from the leaking gas tank of a moving vehicle is lit, the fire can catch up to the tank and blow up the car. Busted Through small scale tests, the MythBusters discovered that gasoline burns at just over 3 miles per hour (4.8 km/h), which is as fast as a brisk walk. They then burned leaking gasoline indoors using both a remote control car and a regular pickup, and the flame did not catch up to the gasoline tank. A car going at the low speed of 20 miles per hour (32 km/h) could easily outrun the stream of fire. Finally, they let the gasoline catch up to the tank, and it did not explode. Finally, trying to cause an explosion, the MythBusters filled the tank with enough gasoline to get the fuel/air mixture into the "butter zone", where the right mix of air and gasoline vapor will cause an explosion. However, not even the fuel/air mix could make the tank explode, completely busting the myth.

Gunpowder Keg

Myth statement Status Notes
One can outrun a trail of burning gunpowder and kick the trail out before the burning powder reaches its explosive destination. Plausible In large scale testing, an even trail of gunpowder was laid out on a plywood floor. Adam outran the fire and kicked out the trail with plenty of time to spare. Jamie gave it a shot, but Adam hindered his attempt and the powder reached the end. The tests showed that the igniting gunpowder did not move very fast, with Adam showing that a brisk walk is enough to overtake the flame. (US narrator Robert Lee called the myth "Confirmed," but Adam and Jamie's verdict was "Plausible.")
A trail of burning gunpowder can set off the keg from which the powder spilled. Plausible The Mythbusters then figured, what if the person failed to make it in time. They laid out a final trail of gunpowder and remotely ignited it. As expected, the keg exploded. Adam called this explosion "the best we've ever done".

Shocking Defibrillator

In these two myths, the Build team tests whether a defibrillator can burn someone if the electricity arcs with...

Myth statement Status Notes underwire bra. Plausible Though the bra did cause a burn, it was only when the wire was exposed and the paddles were placed very close to the exposed wire. This would not be likely in normal circumstances as the paddles would never be placed so close together and medical staff are trained to remove possible obstructions before using a defibrillator.
...a nipple piercing. Plausible Though the nipple piercing did cause a severe burn (and caused cratering in the ballistics gel dummy), it was only when the paddles were placed very close to the piercing. This would also not be likely in normal circumstances; see above.

Episode 89 – "Exploding Water Heater"

  • Original airdate: November 7, 2007

Exploding Water Heater

Myth statement Status Notes
A water heater can explode like a rocket and shoot through the roof of a house. Confirmed In small scale testing, the MythBusters started with a small 6-gallon (23 L) water heater and disabled all of its safety features under the theory of poor installation or neglect. While the water heater eventually ruptured, it did not explode like a rocket. The MythBusters then upgraded to larger 30-gallon (110 L) water heater which exploded with significantly greater force, sending the water heater several hundred feet into the air. In order to confirm the stated myth, the MythBusters obtained a full size 52-gallon (200 L) water heater and built a shack around it with a roof that followed standard California building codes. The water heater eventually exploded, shooting through the roof 500 feet (150 m) into the air and disintegrating the shack. In light of these results, and the fact that there is documented evidence corroborating the myth, the MythBusters deemed it was confirmed.

Blue Jean Myths

The Build team tested two myths that revolved around denim jeans.

Myth statement Status Notes
If a person is being dragged by a horse, the friction caused by the movement will make their jeans catch fire. Busted Wearing full body padding and a denim shirt and jeans, Tory allowed himself to be pulled along the ground by a horse. While the movement and friction did increase the surface temperature of the jeans, it was not enough to cause the jeans to combust. The Build Team then moved the experiment into the lab, where they simulated the friction caused by being dragged by a horse with a power sander. However, when they applied the jeans to the power sander, the jeans were torn apart before they could combust. The Build Team then agreed that friction alone cannot make jeans catch fire.
Shrinking jeans while wearing them in a hot bath for six hours can kill a person. Busted The theory behind this myth is that if a person wore a pair of jeans and sat in a hot bath intending to shrink them to fit, the shrinking jeans can cut off blood circulation to the legs which can cause a lethal clot or require the legs to be amputated. The Build Team experimented with a pair of ballistic gel legs with tubes running through it simulating blood vessels. They then covered the legs in jeans and put it in a hot bath for six hours, but found no change in blood flow. They then had Grant wear a pair of blue jeans and had him sit in a hot bath for six hours. During the experiment, Grant was continually monitored by a medical expert and by the end of the six hours, he was declared healthy and in no risk of death. The Build Team decided that the myth was busted, but reminded the audience that blood clots and cutting off blood circulation are very real dangers and should not be taken lightly.

Episode 90 – "Supersized Myths"

  • Original airdate: November 14, 2007

Supersize Shark

The MythBusters tested the following myths involving Great White Sharks.

Myth statement Status Notes
Sharks can hunt by feeling low frequency sound waves transmitted through water. Busted The MythBusters traveled to the waters of South Africa where great white sharks are abundant and placed underwater speakers in the water. After transmitting sounds at various frequencies ranging from 40-100 Hz and even resorting to high frequency sound, the MythBusters failed to attract any sharks.
The presence of dolphins can deter sharks from attacking their prey. Plausible This myth was born from the stories of dolphins protecting shipwrecked sailors from sharks. The MythBusters built an animatronic replica of a dolphin and took it to the shark infested waters of South Africa. They tested the waters by throwing in a seal-shaped lure to have it attacked by a great white shark barely five seconds after it hit the water. They then placed the fake dolphin in the water with the lure. The sharks approached the lure, but when they saw the dolphin, opted not to attack. The MythBusters replaced the lure with actual bait, but the results were the same, and the sharks appeared reluctant to attack. However, once they removed the dolphin, the sharks immediately began attacking the lures and bait again. With these results and with plenty of anecdotal evidence, the MythBusters decided that the myth was plausible.

Supersize Jet Taxi

This is a retest of the old Jet Taxi myth, because the MythBusters were unable to obtain a full size plane and fans both complaining and mentioning the BBC automotive show Top Gear test of the myth[3] (which was acknowledged ambiguously by Jamie referencing a "British TV Show"). This time, the Build Team tests if the engines of a full size Boeing 747 can flip the following:

Myth statement Status Notes
...a taxi. Confirmed The Build Team obtained a taxi and towed it across the rear of the 747 as it was powering up for takeoff. The moment the taxi crossed the engine exhaust, it was lifted into the air and flipped several times, completely demolishing the vehicle.
...a school bus. Confirmed Like the taxi, the build team towed the school bus across the path of the 747 engine exhaust. Also like the taxi, the school bus was lifted off from the ground; it rolled 1½ times and was completely demolished.
...a small airplane. Confirmed Like the taxi and school bus before it, the airplane was thrown into the air and suffered significant damage when it crossed the path of the 747 engine exhaust.

Supersize Rocket Car

This is a spinoff from a previous myth, the JATO Rocket Car. This time, the MythBusters are testing for the results, not the circumstances. Former Build Team member Scottie Chapman makes an appearance in this segment.

Myth statement Status Notes
A Chevy Impala with rockets can move fast enough to achieve flight. Appropriately Supersized The MythBusters started with small scale tests, and determined that their old JATO configuration was not suitable for the myth, because the top mounted rockets caused the car to veer off course. Instead, they opted to mount the rocket tubes inside the trunk of the car to achieve a more stable trajectory. They then obtained a Chevy Impala (named "Holly" by its previous owner) and made the necessary modifications to accommodate the rockets. To ensure that the car would get into the air, the MythBusters set up a ramp built from two shipping containers. However, when they started the actual test, the car and the rockets exploded, completely destroying the car before it could even leave the ramp. Because none of the central questions of the myth were answered despite the care and expertise that had gone into the test, the MythBusters had trouble deciding what to call the myth. In the end, they agreed that the myth was "Appropriately Supersized".

Supersize Cruise Ship Waterskiing

Myth statement Status Notes
A person can waterski behind a full size cruise ship. Confirmed The Build Team first started by having Tory practice waterskiing. However, instead of waterskis, Tory instead opted to use a wakeboard. After some practice wakeboarding and swapping tow lines between two different boats, the Build Team then tested the myth on a full size cruise ship, the MS Regal Empress. While his first try failed, Tory managed to successfully transfer to the tow line attached to the cruise ship and managed to waterski behind it, proving that the myth is possible.

However, this had already been achieved earlier (2006) with the cruise ship MS Deutschland - see the webpage of the German TV show Kopfball.

Episode 91 – "Shooting Fish in a Barrel"

  • Original airdate: November 21, 2007

Shooting Fish in a Barrel

Myth statement Status Notes
A person can easily shoot a fish in a barrel. Confirmed Because they could not realistically use a live fish to test for the myth, the MythBusters obtained a dead fish and inserted a motor inside of it to simulate swimming. They then placed the fish in a wooden barrel filled with water and fired at the fish with a 9 mm pistol. However, their first shot missed, so Adam painted the interior of the barrel white and added transparent windows to improve visibility. With these improvements, both Adam and Jamie were easily able to hit the fish. They then decided to use a multitude of smaller fish and upgraded their weapon to a shotgun. The buckshot managed to hit some of the fish, but only three out of the total of thirty fish.

They then tested whether just the shock wave could kill the fish; using pressure patches they found it can kill the fish, meaning a person would not need to actually hit the fish.

To put the myth to bed, the MythBusters decamped to a firing range owned by weapons manufacturer Dillon Aero.[4] On location, the MythBusters placed a dead 3-foot (0.91 m) sea bass in a water filled barrel. They then used a Dillon Aero M134 minigun and several thousand rounds of ammunition to destroy the barrel and fish. The Dillon Aero site was referred to on-screen as a 'secret location', because the rounds are illegal in California, where MythBusters is based.

Because of the vagueness of the conditions of the myth, the MythBusters declared that shooting fish in a barrel is easy.

The pressure shockwave of a bullet hitting the water is enough to kill a fish. Confirmed The MythBusters calculated that the lethal amount of force required to kill a fish is 8.15 pounds per square inch (56.2 kPa). However, the instrument that measured psi was not fast enough to register the impact of the bullet, so the MythBusters instead opted to use stickers that measured g-force. After firing a single 9 mm bullet, the MythBusters saw that the shockwave of the bullet was enough to trip all three stickers (50 g, 75 g and 100 g). This means that the shooter does not necessarily have to hit the fish in order to kill it.

Hot Chili Cures

The Build Team wolfs down various spicy peppers to test whether a hot chili mouth can be cured by...

Myth statement Status Notes
...milk. Confirmed The milk was used as a control, because it is already proven to reduce discomfort due to the fats it contains. Grant and Tory used the milk as a measuring stick for the rest of the supposed cures.
...water. Busted The water did not perform as well as the milk, because the discomfort immediately returned once the water left the mouth. Busted The beer helped slightly, but was still not very effective.
...tequila. Busted The tequila initially intensified the discomfort, but when the alcohol kicked in, the numbness induced by it slightly lessened the pain. However, it still was not very effective.
...toothpaste. Busted The toothpaste had no effect at all.
...petroleum jelly. Busted The petroleum jelly failed to work, which made the MythBusters rather disgusted.
...wasabi. Busted Grant reacted violently to the wasabi, stating that it only made his discomfort worse, but Tory stated that he actually felt some relief. However, it still was not effective as milk. (Side note: the discrepancy may be partly because Grant was eating crushed jalapeños, while Tory was eating far spicier habaneros.)

Elephants Scared of Mice

Myth statement Status Notes
Elephants are scared of mice. Plausible Adam first visited Wilke's Wildlife Rescue in South Africa to borrow some mice for the myth. The MythBusters then traveled to Aquila Private Game Reserve to find wild elephants to test on. The MythBusters hid a mouse under a ball of elephant dung, planning to flip the dung over and reveal the mouse when the elephants approach it. When they flipped the dung and revealed the mouse, the approaching elephant was startled and quickly moved away from the mouse. The MythBusters then flipped dung without the mouse under it, but the elephants did not react at all. They then retried their first experiment to confirm their results, and the elephant noticed the mouse and actively avoided it. Even though the elephants did not panic at the sight of the mouse, the fact that they acted cautiously around them was enough to have the myth be considered plausible, as it was not known whether the reaction was due to fear of or empathy for the mouse.

Episode 92 – "Pirates 2"

  • Original airdate: November 28, 2007

In this episode, the MythBusters test several myths based on scenes from the film Pirates of the Caribbean: The Curse of the Black Pearl and other pirate movies.

Rowboat Submarine

Myth statement Status Notes
Two pirates can use a rowboat as a makeshift submarine by walking along the ocean bottom and using the rowboat to hold a pocket of breathable air. Busted On their first test, the MythBusters tried walking into a pool with a rowboat over their heads, but their bodies were too buoyant and were unable to pull the rowboat to the bottom of the pool. To solve their buoyancy problem, the Mythbusters loaded themselves down with over 60 pounds (27 kg) of pirate gear and attempted the myth again, but met similar results. They then weighed the boat down with 500 pounds (230 kg) of weights, but not even that was enough to keep the rowboat under the surface. The MythBusters then calculated that it would take more than 2,000 pounds (910 kg) of force to keep the rowboat and the air pocket underwater, making the myth impractical if not impossible. To explain the scene in the movie, the MythBusters demonstrated that it was achieved through special effects and clever editing.

Buried in Sand

Myth statement Status Notes
A person buried up to their neck in wet sand (dubbed a "sand necktie") cannot escape their inevitable demise. Confirmed Tory was the Build Team member to get buried in sand to test the myth. He was buried in dry sand up to his neck to see if the weight of sand would cause him to pass out, and if not, whether he could escape on his own. Within five minutes, Tory was able to free one of his arms. From there, it took him eighty-six minutes to dig himself out of the sand. However, the Build Team decided to use more accurate conditions, and buried Grant in wet sand, continually adding water to simulate the rising tide. While Grant tried to escape, the water kept pushing the sand back into the cavities he was digging out, immoblizing him. Grant was eventually forced to rely on outside help to escape, confirming the myth that the sand necktie is a lethal and dastardly way to get rid of a person.

Cannonball Chaos

The MythBusters test several cannonball myths involving improvised cannon ammunition and whether they are lethal or not. Using a period cannon (dubbed "Old Moses"), the MythBusters fired various improvised materials that would be found on a period pirate ship at dead pigs to test their lethality. Some of these improvised cannonballs include...

Myth statement Status Notes
...grapeshot. Confirmed The grapeshot is actual period ammunition that pirates used and was used as a control test. The grapeshot destroyed the target.
...bottles of rum. Busted The glass shattered and the rum vaporized during the firing, leaving only small bits of glass to hit the target. Aside from minor superficial damage and the smell of rum, glass rum bottles are harmless.
...cutlery. Busted The cutlery did not cause any noticeable damage. All of the projectiles were spread too far out and lacked the force to cause any lethal damage.
...steak knives. Plausible Because they were placed in a container, the steak knives were all pointing forward and had their direction set. This allowed them to hit the target, causing serious cuts and lacerations.
...a peg leg. Busted When fired, the peg leg was completely destroyed, leaving no visible trace except for wood chips.
...nails. Plausible The sharp, heavy nails caused almost as much damage as the grapeshot, tearing through the target with relative ease. Adam likened the effect to that of a needlegun.
...chains. Confirmed The long, heavy chain remained intact and did the most damage to the target, almost ripping it in half.

MacGyver Mini Myth

During the commercial break, the MythBusters tested this myth as a promo for their upcoming MacGyver special.

Myth statement Status Notes
A person can break a light bulb using drain cleaner shot out of a spray bottle. Confirmed The drain cleaner caused a thermal shock in the hot glass of the light bulb, causing it to shatter. This concept was also demonstrated during the Lethal Lava Lamp myth, when Grant successfully caused a lava lamp to explode by spraying it with water.

Episode 93 – "Confederate Steam Gun"

  • Original airdate: December 5, 2007

Steam Powered Machine Gun

Myth statement Status Notes
The Confederates successfully created a working steam powered machine gun that could fire bullets using centrifugal force. Busted The MythBusters first tried to confirm whether a steam powered machine gun in fact existed. A Civil War weapons expert confirmed that the weapon actually existed and has the blueprints to prove it. However, the gun's lethality and effectiveness were unconfirmed. They then constructed a steam gun based on the blueprints they received, with a pair of water heaters providing the steam to spin the barrel. On their test run, they fired a single round which struck the gun's steel safety shield, creating a deep dent which could potentially cause lethal damage to a person. Satisfied with the test run, the MythBusters took the gun for full scale testing. They tested the gun based on three major factors: a range of 500 yards (460 m), a rate of fire of 400 round per minute, and the fact that the weapon had to be lethal. The gun performed well on the first two criteria, firing five rounds per second at a range of 700 yards (640 m). However, the weapon lacked any lethal force at ranges beyond point blank, and was not very reliable in terms of delivering the bullets to the targets in an effective manner. The MythBusters concluded that as a concept and a machine, the steam gun performed perfectly, but as a weapon, was too unreliable and impractical.

Beating the Lie Detector

Myth statement Status Notes
Through mental or physical means, a person can fool a lie detector test from a polygraph machine. Plausible In order to make the test results genuine, Tory and Grant were instructed to steal money from a safe while the innocent Kari was used as a control. Also, they were promised a reward (first class seats on the next MythBusters trip) for beating the test and a punishment (cleaning and waxing the entire crew's cars) for failing. During the test, Tory attempted to use pain to hide his lying while Grant tried to focus his mind. However, neither of them could beat the polygraph. While they both failed the test, the Build Team decided not to rule out the possibility that there are people out there capable of fooling a polygraph.
A person can fool a lie detector test from an fMRI, which measures brain activity. Plausible Like the first test, all three Build Team members had to steal something to fulfill the conditions of the myth. Each member had the choice of stealing either a ring or a watch and then underwent a lie detector test while being scanned by the fMRI. Like before, there was a reward ($1,000) and a punishment (a trip back to San Francisco via bus; a 3,077-mile (4,952 km) trip) if they passed or failed the test. Both Tory and Kari tried to think happy and fearful thoughts respectively while Grant tried to keep his brain active for the entire test. In the end, Tory and Kari both failed the test while Grant managed to fool the fMRI, making the myth possible; the results showed all three stole the ring when in fact, Grant actually stole the watch (in addition to the ring, Tory also stole a DVD from an adjacent drawer). Resident Frank Kozel under the direction of MUSC provided the equipment for this test.

MacGyver Mini Myth

During the commercial break, the MythBusters tested this myth as a promo for their upcoming MacGyver special.

Myth statement Status Notes
A person can "repair" a fuse box by wrapping a burnt out fuse with a metal foil gum wrapper. Confirmed The metal in the shiny part of the gum wrapper acts as a replacement conduit for the burned out fuse, allowing the circuit to be reestablished when replaced. However, this makeshift replacement may not burn out under excess current like a proper fuse does. Many houses have caught fire because of makeshift replacements for blown electric fuses.

Episode 94 – "Air Plane Hour"

  • Original airdate: December 12, 2007

Talked into Landing

Myth statement Status Notes
An untrained civilian can be instructed how to successfully land a plane over the radio. This is based on the movie Airplane. Plausible This myth, based on multiple airplane movies, posed a challenge to the MythBusters because they could not afford to test it using real aircraft. Instead, they used a NASA simulator. For their first test, both Adam and Jamie decided to see if they could land a plane unaided. However, since both MythBusters had no flight experience and had no idea what most of the instruments and controls did, they both were forced to crash land their planes. In their second runs, Adam and Jamie had Terry, a licensed pilot, give them instructions via radio. With Terry's help, both Adam and Jamie were able to land their planes safely. However, even though the test was a success, Terry pointed out that most modern planes are so advanced that their autopilot systems can land the plane by themselves, negating the need for a civilian pilot. This information, coupled with the lack of any recorded incidents, led the MythBusters to declare the myth plausible.

Point Break Trilogy

The MythBusters test three skydiving myths based on a scene in the film Point Break.

Myth statement Status Notes
A person can free fall for over ninety seconds from a height of 4,000 feet (1,200 m). Busted The Build Team dropped a Simulaid from a plane at a height of 4,000 feet (1,200 m) and measured the amount of time it took for it to hit the ground. They timed the total free fall time at just 31 seconds, which would make the 90-second free fall scene in the movie impossible, especially considering that additional time needed to account for parachuting was not factored in (the Simulaid was simply dropped to the ground, exploding on impact).
Two people can have a conversation with each other while in free fall. Busted To test this myth, Grant skydived out of a plane. A skydiving instructor was to approach Grant while he was freefalling and then attempt to say to Grant, "Grant, if you pull my finger, you will hear a tuba." During the freefall, the instructor yelled the phrase multiple times, but Grant could not hear him because the sound of the air rushing past drowned out his voice. The Build Team concluded that it was impossible to have a conversation in freefall.
By streamlining their body, a person can catch up to two other people in tandem freefalling at terminal velocity in the skydiving position with a fifteen second head-start from 15,000 feet (4,600 m). Confirmed The Build Team first performed several small scale tests using wind tunnels, and demonstrated that objects with a greater surface area do in fact have a slower terminal velocity than objects with equal mass but smaller surface area. For the full scale test, Tory, while in tandem with another sky diver, jumped out of a plane and assumed the skydiving position. Nick, a professional skydiver, gave Tory and the sky diving instructor a fifteen second head-start and jumped out of the plane after him and assumed a streamlined posture. Twenty seconds after leaving the plane, Nick closed the distance between himself and Tory and passed Tory just as he was deploying his parachute. With such definitive results, the Build Team declared the myth confirmed.

MacGyver Mini Myth

During the commercial break, the MythBusters tested this myth as a promo for their upcoming MacGyver special.

Myth statement Status Notes
A person can stop a sulfuric acid leak with chocolate and hot water. Confirmed Grant and Kari demonstrated that the myth was possible, showing that the sugars in the chocolate reacted with the acid to form a plastic mass that plugged up the leak.
