A Kugel ball is a sculpture consisting of a large granite ball supported by a very thin film of water. Water flows beneath a very heavy, perfectly spherical rock from a spherical concave base with the exact same curvature. A Kugel ball can weigh thousands of pounds, but because the thin film of water lubricates it, the ball spins.
