Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of magnetic field. Originally created by NASA to better control liquids in zero gravity, this one-of-a-kind substance continually increases in popularity as more people learn of its capabilities.
Comprised of nano-scale magnetic particles suspended in a transparent liquid, undisturbed Ferrofluid forms into a smooth pool. But when a magnet is brought close, it reacts in strange and fascinating ways. You can even make it dance! For ages 12 and up.
