It's like magic, but you don't need to be a magician to get it to work. 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 needs is a driver and a smooth, flat surface. The PlasmaCar is adult-friendly, too. For starters, it doesn't require an expensive power source that needs constant replacement. No batteries, no power-cells, no liquid fuel-just the occasional cookie or two. It's quiet too-the only sound you'll hear is the sound of its wheels. It provides kids with plenty of exercise, more so than most toys.
