●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 the included neodymium magnet(s), you can spike, toss, drop, pull, and bridge the ferrofluid. You can even make it dance.
Ferrofluid Magnetic Display
★Desktop display is fun with ferrofluids
★Use the magnet to make the fluid dance!
Leaving the magnet against the ferrofluid for extended periods of time can cause irreversible damage to your ferrofluid such as it no longer being able to spike. When not in use, keep the included magnet attached to the cap of the bottle or in a separate location.
Observe magnetic flux lines by placing a magnet close to the ferrofluid.
