New miracle Donbass Arena
Today, June 23, in front of the stadium Donbass Arena installed the world's largest rotating ball on the water.
Tridtsatitonny ball created by German craftsmen from granite special breed (Tittlinger). Its diameter is greater than 2 and 7 meters. Despite the large size, he looks very similar to a soccer ball. Gray elements on the surface - a polished granite and black are sandblasted and acrylic coating. Stand ball is also not small, diameter of 360 cm and a weight of 12, 5 tons.
Huge granite ball will rotate under the pressure of two water jets. Rotation is due to water pressure and thanks to a perfectly round shape. The deviation of the granite ball on the shape of a perfect sphere is less than 0, 1 mm.
