Create your own lightning with these time-tested devices that have delighted students for decades! Named after the inventor Van de Graff, an American physicist, Van de Graaff generator produces low-amperage static electricity that can be “shocking” but perfectly safe. Two rollers inside a plastic column create and carry static charge up to the aluminum collector globe. You can draw out this static charge in a burst of lightning - or you can set each hair on your head on end! Our instruction booklet tells you how to raise hair; produce lightning and electric wind. |
