Have you ever walked through Tomorrowland and spotted that giant stone ball near Auntie Gravity’s and thought, “what the heck is that?” There is no label or placard, but it’s a Kugel Ball.
Kugel Ball fountains are engineering wonders. They consist of a large granite or marble sphere floating on a very thin plane (less than the thickness of a credit card) of water in a perfectly fitted socket. The water, pumped from below, lubricates the stone and creates a pressure such that the solid, heavy stone is easily rotated!
