Ferrofluid Magnetic Display

Utterly addictive

Ever find something that is so simple, but so fun that you lose track of time? That's how we feel about the CZ Ferrofluid Magnetic Display. At first, we were like, meh. Magnets in a bottle? Then we got our hands on it and it was already 6 o'clock and we hadn't done any of our work. Oops.

Neato facts about ferrofluid:
It's a portmanteau (ferromagnetic + fluid). Did you know that even though portmanteau comes from French, the French call a portmanteau a mot-valise? Trufax. Ferrofluid is a colloidal liquid made of particles less than 10 nanometers in diameter. When subjected to a magnetic field, the nanoparticles form regular patterns of peaks and valleys.

In electronics, ferrofluids are used to form liquid seals, like to prevent debris from getting into a hard drive.

Cancer researchers use ferrofluids in an experimental treatment called magnetic hyperthermia.
