Looking for a new “toy” for your office desk? Newton’s Cradle is probably getting pretty boring by now, right? Colorful Ferrofluid in a Bottle uses science to distract and amuse you, for a few moments anyway.

Ferrofluid is a magnetic liquid that reacts very readily to the presence of a magnet. This ferrofluid has been bottled for play. There’s one more change, the fluid which is usually black as night has been colorized to blue and gold. Super pretty and super distracting. The ferrofluid is suspended inside of another clear liquid solution.

You interact with it by holding a magnet up to the bottle. The ferrofluid jumps at the magnet and you can experiment with holding the magnet at different distances, moving it in different ways, or “tossing” the fluid for cool effects. You can make it spike up, drip, pull it, or drop it like a bad habit. Opening the bottle is likely not advised but it does come with a magnet. If you have another magnet then you can test it’s reaction to two different pulls. The Colorful Ferrofluid in a Bottle is $59.99.
