Ferrofluid is an iron-based liquid that reacts in the presence of a magnetic field.
Comprised of nano-scale magnetic particles suspended in a transparent liquid, ferrofluid aligns itself to a magnetic field, making it easy to visualize the field.
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.
