This wooden car is powered by an elastic band. When the potential energy of the stretched elastic is converted into kinetic energy of motion, the car will travel about 3 meters (10 feet). Students can experiment by varying the method of winding the elastic, the number of turns, adding weight, and the type of surface used.
