Build your own models powered by air pressure and water to learn about the laws of physics
A larger, super-charged version of our original Air+Water Power kit, this kit allows you to build more powerful models using two different air-and-water-powered systems - water-jet propelled cars and hydro-pneumo (water-air) powered engines
The hydropneumo system in this kit uses a larger, more powerful self-contained air-and-water turbine system as a motor
Two pressurized air-water tanks are included, allowing you to build two water-jet propelled cars simultaneously and race them against each other
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 cargoes the fastest, and whose hydro-pneumo cargoes the farthest! 60-page color instruction book
