Electrostatic Generator 200,000V (Assembled)

Description

Create your own lightning with these time-tested devices that have delighted students for decades! Named after the inventer Van de Graaff, an American physicist, this machine produces low-amperage static electricity that can be "shocking" but perfectly safe. Two different pulleys inside a plastic column create and carry static charge up to the polished alumimun 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; experiment with St. Elmo's fire or electrostatic attraction and repulsion.
