Solar Car Book

The Solar Car Book is full of illuminating solar science facts and comes with everything you need to build a cool solar-powered racecar: wheels, axles, motors, wires and a genuine one-volt solar cell. No glue, no nails, no tape and (best of all) no batteries required. Build this car today and it will run forever, thanks to that big battery in the sky. This book includes rubber bands that contain Natural Rubber Latex which may cause allergic reactions.
