Physical Attraction : magnetic art

Here's a couple videos involving magnets. The first one is one of many videos I've seen with FerroFluid (an oily fluid with magnetic particles suspended in it). This was developed by Japanese artist, Sachiko Kodama.


The second video is from some company called NASA. They're not too good at making movies although the technology the used is amazing. They might be better suited for space science and aeronautics.
