Ferrofluid is a highly magnetized liquid in the presence of a magnetic field. Comprised of nano-scale magnetic particles it is 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 way. With Ferrofluid in a bottle, you can safely and easily play with this unique substance. Using two included neodymium magnets, you can spike, toss, drop, pull, and bridge the Ferrofluid.
