Scratch Holography
Date: Tue, September 13, 2005
Jim is going to looooove this one.. Scratch Holography.
And take a look at a list of other similar odd science playthings by the same author. I especially like the article on using a telescope combined with a solar cell connected to an audio amplifier to do UFO detection. DC = Venus, 120hz = streetlamp, "WizzlefiblfrtzYUBYUB!!!" = ?
Hours of entertainment can be found here, trust me.

Jim:
Here's the actual site that I used when I built my little Van de Graaf generator. The link was on The Amateur Scientist.
Dave:
A lot of his stuff is up on Eskimo.com, which was my favorite multiline bbs when I lived in Seattle. Eskimo has been around since... ouch.. the early 80's? Really cool system, run by a really cool guy.

The Amateur Scientist is one of the cooler websites for people who like to build their own science apparatus and experiments. I used it when I built my first Van de Graaf generator using a rubber band, a small motor, some wire and a pop can.
