Sachiko Kodama's Ferrofluid Sculptures

Ferrofluid is a magnetic liquid. Bay Area natives may remember playing with an exhibit at the Exploratorium in which you pass a powerful magnet underneath a black fluid and watch as smooth spikes arise and merge. Japanese artist Sachiko Kodama uses ferrofluids and electromagnets to uncover the surprising creative possibilities of this medium. I've just received my own bottle to experiment with.
