Skyrocket

Skyrocket

A skyrocket is a type of firework that uses a solid rocket motor to rise quickly into the sky. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted. Sky rockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins. In the United Kingdom firework rockets are sold by weight, e.g.: 4 oz, 8 oz, 1 lb. This is not the weight of the rocket itself, but rather of a lead sphere whose diameter matches that of the rocket motor, officially defined as "The weight of a lead sphere that is "just" supported by a tube that the rocket motor will "just" fit into."

kyrockets and their use in professional displays

A common misconception about professional fireworks displays is that skyrockets are used to propel the pyrotechnic effects into the air. In reality, skyrockets are more widely used as a consumer item. Professional [http://www.pyroinnovations.com/devices.html fireworks displays utilize mortars] to fire aerial shells hundreds of feet into the air, not rockets. There is however, a rising effect known as a "tail," which is attached to the outside of the shell to leave a trail of sparks during ascent, and is meant to give the look of a rocket rising into the sky. Mortars are used as opposed to skyrockets for safety reasons. Once the shell leaves the mortar it is no longer under propulsion; therefore, can not re-direct itself towards the crowd.
