Ferrofluid is a liquid that does really amazing stuff when you get a magnet close to it. Make sure you watch past the halfway point of the second video, as that's where the really good stuff is.
Hi
I'm Jim Biancolo, and this is my weblog. It's mostly links to stuff I find interesting (here are some of my favorites), but some stuff is mine. I also created Listology in the previous millennium (raised it from a pup but I stopped playing with it and I felt bad so I gave it away to a good home), and the fitness weblog Lean & Hungry Fitness, which is gone, subsumed, but it was a cool domain while it lasted.

I've turned off comments, but I'm not a complete recluse. I like email (feedback, tips, suggestions, etc.). I am also, tentatively, on Twitter.
