According to the Wikipedia article… “Ferrofluids are colloidal mixtures composed of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid, usually an organic solvent or water. The ferromagnetic nanoparticles are coated with a surfactant to prevent their agglomeration“. Which essentially means “Oily Magnetic Liquid” capable of doing absolutely stunning things when near an electromagnetic [...]

We always knew it but this totally confirms without a doubt that science is awesome! via
