Build your own models powered by air and water pressure to learn about the laws of physics. This unique kit allows you to build two different air-and-water-powered systems: water-jet propelled cars and hydro-pneumo powered engines (which simply means air pressure and water pressure). The hydro-pneumo system uses a self-contained air-and-water turbine system as a motor.

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 fastest!

The 48-page color instruction book included in this kit illustrates the step-by-step assembly of each model and related principles so that children learn through playing. The 165 building pieces included in this set are compatible with those in all the Wind Power 2.0, Remote Control Machines, and Solar Power kits.

Ages 8 and up.
