A long while back ( >1 year), someone told me to look into these things called "ferrofluids."
I looked around some, thought they looked pretty cool, and eventually found a couple videos for download.
However, they were in QuickTime MOV format, and - at the time - I really wasn't interested in installing Apple's crappy windows player just to have a look, so they dropped back into a lesser-used section of my hard drive.
About a week ago, I rediscovered these old vids and, using K-Lite's wonderful QuickTime Alternative (http://www.k-litecodecpack.com/), I was amazed to discover just what ferrofluids can do.
In the simplest terms, a ferrofluid is like a magnetic liquid. By dissolving certain magnetic metals in certain liquids, you can produce a oily substance that inherits some of the properties of a metal! The most coolerest of these is magnetic attraction.
By placing a magnet next to this pool of liquid, it begins to "spike" out in the directions of the magnet's fields. The result looks like a liquid sea urchin!
Descriptions and tiny GIF animations don't do ferrofluids justice, so I've put the 3 videos I found "way back when" on my server.
You can find them here (http://ff3pc.no-ip.com:81/ff/).
EDIT:
Looking around, I've found a few more videos that have popped up since that last time I searched for them. Links have been added to the above page.
EDITEDIT:
Ah, I knew I had downloaded a 4th video. Added that to the page as well.
