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 this amazing magnetic fluid, you can safely and easily play with it using the two included neodymium magnets. You can spike, toss, drop, pull, and bridge the ferrofluid. You can even make it dance. It really makes a great interactive display that will look awesome on your desk or coffee table. Everyone will enjoy playing with it.
- The fun of the Ferrofluid in a mess-free, sealed display bottle! Tough, impact resistant glass offers easy viewing and interaction with ferrofluid.
- Each glass bottle contains 2 ounces suspension solution (mostly water, plus some secret ingredients) and a glob of ferrofluid.
- Do not open the black cap since it is sealed tightly for safety or you will get stained by the ferrofluid liquid.
- Please do not leave the magnets on the bottle all the time even if you don't want to play it.
- The liquid in the bottle is non-toxic.
