Static Experiment With Light Bulb

Materials needed - 1 or more burned-out electric light bulbs.

Experiment - Take the bulb and hold it near a rapidly moving belt, connected with machinery which is not grounded. Hold the brass end of the bulb close to the belt and sparks will usually jump from the belt to the brass cap.

Charge in this manner for about five minutes, then take it away. Offer it to someone, holding the bulb by the glass end always. When the person goes to touch the brass end a nice hot spark will jump to him, giving a considerable shock.
