● 15 models are propelled by a hydro-pneumatic motor. ● Two different systems: * System one has 7 models exhibiting the hydro-pneumatic powered system. – Ideal for both indoors and outdoors since water is circulated and contained within. * System two has 8 models exhibiting a water-jet propelled system – Ideal for outdoors because water gets sprayed out. ● Includes specialty parts: water tanks, secure pump, nozzle, air-water power pack.
This unique kit allows you to build two different air-and water-powered systems : water-jet propelled cars and hydro-pneumatic powered engines. The hydro-pneumatic system uses a self-contained air-and-water turbine system as a motor. The water-jet propelled cars are a fun outdoor activity, while the self-contained hydro-pneumatic powered models are fun both indoors and outdoors. Compete with your friends to see whose model goes the farthest!
