Ferrofluid In A Bottle (Magnetic Liquid)

 

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 the included neodymium magnet(s), you can spike, toss, drop, pull, and bridge the ferrofluid. You can even make it dance.
