Ferrofluid / Liquid Metal

Ferrofluid is the oddly-satisfying liquid metal that spikes, dances, and flows under the pull of a magnet. Our ferrofluid desk toys and Bluetooth speakers turn that mesmerizing magnetic motion into the ultimate focus-and-fidget centerpiece — watch black liquid leap to your music or shape it by hand for instant stress relief. The most-watched gadget on any desk. Small-batch, tracked shipping.
