The Original Shatterproof Propeller!
Spin this shatterproof Aero-Props Hand Powered Helicopter and let it rip high into the sky! Play catch or make a target and see if you can land the Aero-Props on it. Try to create as much RPM that you can with your two hands put together flat, palm against palm. Unlike the Wacky Whirler and other inferior copycat brands, the Aero-Props will not shatter or crack because it is made of a durable, flexible high-tech material. Aero-Props is scientifically designed to allow flights of pinpoint accuracy and precision and works on the same principals of flight that all propeller airplanes use, that of lift and thrust. Some assembly required, but easy enough for a monkey.
