Build a lightning-fast race car powered by nothing but air no batteries or electric motor required!

Use the sleek, integrated pump to compress air into the tank, then put the car on the ground and watch it zoom away! The innovative air-powered engine works just like a combustion engine in gasoline cars, minus burning fossil fuels. The engine intakes pressurized air from the tank, which pushes the piston forward. The piston knocks against the valve, releasing air into the cylinder, which pushes the piston down, rotating the car’s rear axle. The piston expels the air from the cylinder, creating a puff of exhaust and an authentic engine sound. Vroom! Vroom!
