A kugel ball is a perfectly spherical stone that is set into a matching, perfectly concave cup. Water is then forced in from the bottom of the cup and that creates an evenly distribyted, incredibly thin layer of water. The ball, no matter how heavy, can then be moved on the liquid surface as though it weighs nothing at all.
When I stopped by at 7:30 AM, the ball wasn't moving. A few strong pushes (it DOES way 27 tons) and it was on its way, spinning in a circle on top of the water. Very, very cool.
The Grand Kugel is the largest construction of its kind in the world. It sits in a place of honor in front of the Science Museum of Virginia. If you're visiting the museum, step out and stop (or start) the Grand Kugel's spinning.
