| Create your own lightning with these time-tested devices that have delighted students for decades! Named after the inventer Van de Graaf, 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. |
| 10-285 pictured |
| 10-085/10-086 and 10-285/10-286 have a negatively charged collector. |
