Ever wonder what would happen if you took fine iron powder, mixed it up thoroughly in a liquid, and then subjected the result to varying magnetic fields?

Apparently, the result is sometimes art.  Such is the work of Sachiko Kodama, as shown in the following videos.

Morpho Towers

Protrude, Flow

Very interesting.  I liked the Morpho Towers one especially.  It looked like there was a light possibly magnetic ceiling on the last one…that seemed to catch and hold some of the metal before dropping it when specific loud sounds were expressed.

(It reminds me of the Tower of Babel that some stories say crumbled to the ground after the crowd stomped in unison around it (I think for days) while clanging loud instrumentation and voice also.)  and   However it fell, the Morpho Towers reminded me of the stories.

I seem to recall anaritcle about being able to make the stuff, using laser copier toner and vegetable oil, though the resulting stuff is basically ink, so it’ll stain everything. But yes, ferrofluids are awesome.

Non newtonian fluids are good fun as well.

For optimal fun: Non-newtonian ferrofluids!

Yes, they DO exist!

http://www.thinkgeek.com/geektoys/cubegoodies/5ac8/ under the ‘black hole’ listing. Not as dramatic as standard ferrofluids, but still awesome.
