This unique set lets you build two different systems: water jet cars and hydro-pneumatic machines. The hydro-pneumatic system uses a self-contained air-and-water turbine system as the driving force. Water jet cars are a fun outdoor activity, while the self-contained hydro-pneumatic models are fun both indoors and outdoors. Compete with your friends to see which model is the fastest!

These models use two basic systems:

1. Hydropneumatic system: Here, the models are powered by a motor that combines air and water, keeping the water inside the system. It is ideal for both indoor and outdoor use.

2. Hydropropulsion system: This method uses water to propel the models, making it suitable mainly for outdoor areas as the water is sprayed outwards.

Gigo Water Power is an excellent tool for understanding the basic principles of physics and renewable energy sources in a practical and fun way.
