This light bulb is powered by static electricity. To light it up you just hold it and slide your feet on the floor. The static electricity created will power the bulb and give out light. Although not practical due to the low amount of light it can generate, it would make for a good experiment in static electricity for kids. It costs $4.95 and is available from Edmund Scientific.
