Ferrofluid is an astonishing liquid that reacts in strange and unexpected ways to the influence of a magnetic field. The fluid is composed of nano-scale magnetic particles suspended in a transparent liquid. Undisturbed ferrofluid forms into a smooth pool, but when a magnet is brought close, the liquid springs into action, forming bizarre structures resembling a sea urchin, a waterfall, and more, depending on the distance and strength of the magnet. The fluid is encased in a glass vial, allowing you to safely and easily play with this spectacular substance. Using the two neodymium magnet tools and two spare magnets, you can spike, toss, drop, pull, and bridge the ferrofluid. You can even make it dance! Ferrofluid makes for a totally unique executive gift, and serves as an excellent conversation piece, or as a scientific amusement for busting boredom.
