Reason #2 why I feel like I'm working in a pre-bust dot com: The programmers down the hall (yes, the same ones who had a Halo tournament in the conference room a couple weeks ago) have bought some extra strong magnets. As in, so strong you could hurt yourself if your finger got stuck between them. So strong they don't like to sell them to the public, and he had to call the company and promise to wear eye protection before they would sell them to him. (Apparently magnets this strong can damage themselves when they snap together, creating metal shards that could get in your eye. Who knew.)
I'm not sure exactly why he wanted these magnets. Just to play with, I suspect. He built this freaky apparatus that's basically a tube with a magnet on each end, and another, loose one in the middle. By quickly removing shielding from the magnets on the end, he can make the one in the middle bounce up and down in the tube. I have no idea what it's for, but it certainly is neat to watch. Also the tube is made out of a bong. No, he didn't have one lying around. He went and bought one just for this purpose, because it was the only thing he could find that was the right shape, clear, and sturdy enough.
The magnets are short cynlinders. I was thinking they were about as wide as a can of soup, but looking again they're more like the size of a can of deviled ham. Mmmmm, deviled ham. He padded them (after catching a finger between them, ouch) and attached strings that make them a little easier to work with. The strings led to a pastime I'm calling "wacky magnet fun":
Hang one of the magnets from the handle of their office door. Hang the other from another door that's close by. Bring the magnets together, but use doorstops (or two programmers) to hold the doors apart. The magnetic field is strong enough to hold them up, even several inches apart. Now you can poke the magnets, put your hand between them, even move one up or down and watch the other move accordingly. It's wacky magnet fun!
I took a few photos this afternoon:
Here's the apparatus for making the magnet slide up and down.
