First of all you are probably wondering what the hell Ferrofluids are? These are liquids that become strongly magnetized in the presence of a magnetic field. So that means when you put a magnetic in close proxemity to these fluids they act all crazy and dance around.
What happens when you crack open a glowstick and dump that into the mix, a whole lot of awesome that's what. You think LED screens are cool, image if DJs had giant glowing Ferrofluid visuals.
Just add a blacklight and let the fun begin. Check out the video below from Physics Girl that we found on the Zamnesia site. Ravers can get all Billy Nye Science Guy too!
