Build your models powered by air pressure and water to learn about the laws of physics. Construct 30 models including pressurized water guns, air-and-water turbine driven cars, rocket cars, and jet boats. 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 goes the fastest, and whose hydro-pneumo car goes the farthest!
