My wife's best friend is a second grade school teacher. In a few weeks she is going to have me in to discuss electricty. It is part of the curiculum and I guess it makes it more interesting to have someone "special" come in.
We are supposed to do a circuit, so I was thinking maybe of a potato circuit, but I'll have to google it, I have never done one, just heard about them. But I was also hoping to come up with a demonstrtion that had a little bit of a wow factor. My brother has an HID lamp testor thats pretty cool, basiclly it will make an FO32 kind of glow while you hold it in your hand. Also, I recently discovered that if I shuffle my feet on carpet to get a good static charge with FO32 in hand, and then discharge by touching the end of lamp to ground, I get a little flash. In a dark room that might me neat.
Any ideas? Something a little safer than a Jacob's ladder?
