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′.
