Plasmacar

Vendor: Plasmart
Type: Games/Toys

This spectacular vehicle has to be seen to be believed! It has no pedals, no battery, no power source other than the child driver .. and it can to do 10 kph, turn on a dime and move backwards.

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.
