Balloon helicopter

Balloon helicopter

A balloon helicopter is a toy helicopter comprised of a latex balloon and a plastic propeller. The propeller is driven by the pneumatic action of air escaping from the balloon, traveling through nozzles embedded within the center of the propeller. The propeller's rate of rotation increases as air continues to leave the balloon, creating lift and causing the device to fly in an upward direction.

A typical balloon helicopter, at full capacity, can fly for approximately 20 seconds and can attain a height of approximately 12 meters (40 feet).
