Tarn granite globe VIRGINIE – RICHMOND – USA Sciences Museum. (2005)
The 29-ton Tarn granite globe Mary Morton Parsons Earth-Moon Sculpture — better known as the Grand Kugel (kugel is German for ball) — is recognized by the Guinness World Records as the world’s largest floating-ball sculpture, thanks to a jet of water.
The kugel revolves 360 degrees in all directions and actually floats on a thin film of water. The globes of the earth and the moon float on water so that Museum visitors can turn them. Although the globe weighs 29 tons (29.3 tonnes) the kugel phenomena makes it light enough for a child to move it.
