Air + Water Power - Experiment Kit

Help children learn about the laws of physics and air and water pressure. This unique kit allows you to build two different air-and-water-powered systems: water-jet propelled cars and hydro-pneumo (which simply means air pressure and water pressure) powered engines. Construct 15 models including a truck, excavator, radar car, tank, antique car, helicopter, motorbike, backhoe, rocket car, forklift, roadster, propeller plane, grinder and cutting machine. The water jet propelled cars are a fun outdoor activity, while the self contained hydro pneumo powered models are fun both indoors and out. Compete with your friends to see whose water jet propelled car and hydro pneumo car goes the farthest. Kit comes with everything you need: 165 building pieces and 48-page instruction book. Suitable for ages 8+.
