Ferrofluid are liquids that become profoundly magnetized in the presence of a magnetic field, making them preposterously cool for desk display. And that's where the Klock comes in. An enormous glass bottle with crystal clear optics and an attached magnet, the Klock is one of the largest ferrofluid displays on the market and offers up a generous 2.5ml of ferrofluid to keep you and any bystanders endlessly captivated.

  • Uses only EDU grade ferrofluid & proprietary suspension liquid to produce the best displays in the world
