Have you seen this girl?

A Japanese artist(?) has made a pretty creepy video of what he calls Ferrofluid sculptures. I have to say, this video creeps me out, but it does use ferrofluids, which are pretty awesome. A ferrofluid is a dispersion of iron nanoparticles in (usually) water, which can interact with magnetic fields to generate corrugated patterns that look like this:



Ferrofluids are more than just artsy and freaky-cool. Its magnetic properties have found use in the IT, optics and defense industries. They will probably be partly responsible for this guy looking for Sarah Connor.

And for the truly bored during this Festivus break, here's how to synthesize your very own ferrofluids. Have fun!

Ok, I finally got what you are talking about: the "terminator" in Terminator II. And Sarah Connor is the good guy's mom. Is that your application in the defense industry?

OH. Duh.

I can imagine some prectical jokes, with the ferrofluid in NMR room.

(Getting the stuff out from the magnet would be the only drawback:)

I think I would maybe rather deal with ferrofluid in an NMR magnet than this :)
Although both would be troublesome, I guess.

HI

Very old comments but good to read ....I could not actually make out who’s Sarah Connor as Felix said "And Sarah Connor is the good guy's mom" , anyone know?
