Description Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field. 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, Ferrofluid reacts in strange and fascinating ways. With Ferrofluid in a bottle, you can safely and easily play with this spectacular substance. Using 2 included neodymium magnets, you can spike, toss, drop, pull, and bridge the Ferrofluid. You can even make it dance. • Comes with a Teacher’s Guide • For ages 12 and up, not a toy • 2 oz • 2.11″ L x 1.13″ W x 3.53″ H
