The PlasmaCar is a mechanical marvel that makes use of that most inexhaustible of energy sources, kid-power, by harnessing the natural forces of inertia, centrifugal force, gravity and friction. It's so easy to operate; all it need is a driver and a smooth, flat surface. The PlasmaCar can go an exhilarating but kid-safe 2.8 meters per second; that's over 6 mi/h. When kids feel the need for speed, and have all that energy to burn, this is the right toy.
Right now, my nieces are obsessed with their scooter-like ripstiks. But they might just like these PlasmaCars, too. They're speedy (6 mph!) -- and there's a lot shorter to fall.
