The Water Jet Propelled Car Kit

This is the kit that allows children to build a hydro-powered rocket car and 29 other water- and air-propelled models. Each model is powered by a plastic tank that holds air and water and releases the pressurized, zero-emission fuel into a turbine motor, sending a sports car, hydroplane, or tanker truck racing. Children can learn about the power of hydrodynamics by racing two cars against each other at speeds up to 8 mph and up to 40' or by constructing a pressurized double-barrel water gun that shoots water up to 25'. The 176-piece kit consists of interlocking plastic pieces that snap easily into place, eight rubber wheels, and a hand pump for filling the tanks with air. Includes a 60-page manual with color illustrations and detailed, easy-to-follow instructions. Ages 8 and up. (3 1/3 lbs.)
