Tesla's Egg of Columbus Science Toy! 🟡 Gadgetify
Nikola Tesla’s Egg of Columbus was first showcased at the 1893 Chicago World’s Fair. It was designed to demonstrate rotating magnetic fields. This is a cool invention that can make a metal egg stand upright as it spins. We have already covered various toys inspired by it that can achieve the same effect. This Large Tesla Egg of Columbus is as close as it gets to the original model. It features a concave tray made of acrylic to allow the egg to rotate more smoothly.
