Science Xplained: Fun Ferrofluids video

Liquids that respond to a magnet? This is not science fiction, but science fact. In this segment, Dr. Ainissa Ramirez, shows the wonderful world of ferrofluids, which are iron particles floating in a liquid. When a magnet is nearby, the ferrofluid makes weird shapes and increases in viscosity. Dr. Ramirez also demonstrates how you can make a ferrofluid at home using breakfast cereal.

Ferrofluid Magnetoscope

The Ferrofluid Magnetoscope, by Michael Flynn, is an exhibit component that allows cooperatively-interactive control of a levitating liquid sculpture using a pair of magnet positioning handwheels. Visitors explore the properties of ferrofluid and learn about nanoscale science. It is available for sale at FunExhibits.com
