Ferrofluid is dark oily magnetic material with amazing properties. When an external magnetic field is applied to the Ferrofluid inside the Nano Drop bottle, the magnetic particles in the Ferrofluid orient themselves almost instantly to the magnetic field lines of the included Neodymium magnet. This creates amazing spiky fractals and geometric forms that allow you to see the magnetic field of the magnet in 3 dimensions. When the magnet is removed, the particles go back to their normal alignment very quickly. This Ferrofluid Nano Drop desk Toy is sure to amaze everyone at the office!
