Pet-Star water rocket car

The Pet Star water rocket car is an environmental friendly vehicle.

 

A Pet bottle is used to stock air and water. The air is pressurised with a bicycle pump . The water is expelled because of this great pressure and pushes the car forward (action<>reaction principle).

 

This project helps to understand the abstract notion of energy efficiency. The more the system is cleverly designed and the further the car will travel (with the same amount of energy).

 

Another interesting point of this project is the ability to stock in a bottle the body energy of the 'pumper'.

 

There are many possible designs. The model we publish can be freely modified and surely improved. 

 

Pet Star is also a competition organized by the Do-It-Werkstatt. Schools competed by building models of water rocket cars. The best model traveled a distance of 78 meters.

 

Feel free to visit the Do-It-Werkstatt site, and learn more about the current competition.
