Invented in 1855. Re-engineered in 2026.
Say hello to the most satisfying way to drop the ball. Inspired by Léon Foucault’s experiments in 1855, Eddy puts electromagnetism in the palm of your hand. Drop the neodymium magnet through the tube and watch eddy currents put the brakes on gravity - no batteries, no tricks. Whether you’re taking five from work or showing it off to anyone within flipping distance, its silent, slow-motion fall is endlessly satisfying.
Available to pre-order now, ready to make your desk a little more current. Eddy, steady, go!
MetMo Eddy is a precision-machined magnetic desk toy that brings eddy currents and Lenz’s law to life.
