 | 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 DIYs project helps to ... »
