Inspired Designs Nano Ferrofluid Display

Liquid magnet in a bottle.

If you want something cool to display on your desk and play around with, you need to get Inspired Design’s Nano Ferrofluid Display. This intriguing little plastic tube contains a patented suspension liquid and high quality ferrofluid, which will react to any magnetic force by “dancing” or through the “buzzsaw effect.” The display also looks cool enough to serve as a conversation piece or just an accent to any room.
