Look closely. Those are nano particles, moving and gooving to the music. I can’t stop watching. This is awesome!

Ferrofluids are composed of nanoscale ferromagnetic particles suspended in a carrier fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration (due to van der Waals and magnetic forces). Although the name may suggest otherwise, ferrofluids do not display ferromagnetism, since they do not retain magnetisation in the absence of an externally applied field. In fact, ferrofluids display paramagnetism, and are often referred as being “superparamagnetic” due to their large magnetic susceptibility. True ferromagnetic fluids are difficult to create at present. [Wikipedia]

Yeah Chris, that stuff is pretty cool.

Did you know that you can buy Ferrofluids on eBay?
Yup – the only problem is that it evaporates rather quickly, so you’ll need to keep buying more.

Yikes! I can see it now: “Here, honey, drink this dark fluid while I crank up the stereo…”
