For every force there is an equal but opposite force. This you can easily prove with this nifty, inexpensive kit that will turn an empty bottle into a Bottle Jet Drag Racer.

The special low friction wheels and axles are easily mounted to the chassis and an empty bottle acts as air reservoir. The air in the bottle is put under pressure and a supersonic jet of air propels the car through a small pin hole nozzle. The instructions show you how to make a car, but a boat, rocket on a line or even a bottle plane might be possible. This is an exciting workshop item and some suggestions are included to organize a school drag race.

Included: Plastic wheels, axles, car valve, bottle lid, chassis and detailed instructions
Required: Plastic soft drink bottle (any size), hand pump, matches and scissors.
