Filmmaker Kim Pimmel combined ferrofluids, a magnet, soap bubbles, and dye to create this mesmerizing short video. Science + art = awesomesauce.

Ferrofluids are basically just iron nanoparticles suspended in a liquid. In the presence of magnets, they do some pretty cool things. For instance, ferrofluids flow to place where the magnetic flux--the strength of the magnetism--is strongest. So if you magnetize the screw from a meat grinder so the magnetic flux is denser at the top than it is at the bottom, the ferrofluid will climb the screw like staircase.
