Environmentally safe, non-toxic and clean. This kit gives children a chance to learn about new forms of clean energy, while building and powering their very own kit: just add saltwater and roar! No batteries required! By putting a few drops of salt water into the fuel cell the water reacts with the metal sheets inside, powering your car and making it move.
Ages: 10+
