Even though the ball weighs a massive 10000kg, even a small child can change the course of it and send it into an accelerated spin. There are no belts, pulleys or wheels used to make the ball spin. It is floating on water.
The Granite sphere fountain comprises two key elements: the ball itself and the socket it sits in. Cutting these two is a very complicated process as any large differences between the contours of them will prevent the ball from turning properly or sitting in the socket. The ball and base are machined at the same time to ensure any differences between them are minute. When finished and the ball is placed in the socket, the space between the two will be less than the thickness of a business card.
You can spin ball heavy weight 5 ton of granite!
You can spin the granite ball because it is floating on water. The water pressure is only about 3 pounds per square inch .in the gap between the ball and the cup. There are enough square inches for this pressure to hold up to tons’ weight of granite, marble or any stone.
Water is pumped up from beneath the socket. This lubricates the sphere and puts pressure on it, forcing it to turn gently. Once the ball has begun to revolve, it will continue to do so until the water is shut off. The sphere rotates on a film of pressurised water and its direction can be changed by the touch of a hand. The sphere floating 360 degrees in all directions and actually floats on a thin film of water. Once started, the ball continues to rolling until someone, even a child, stops it, changes the direction of its spin, or sets it on an accelerated twirl.
The pressure of the pump in this exhibit is very very low, at 3 pounds per square inch (psi). Other giant granite sphere operates at higher pressures, between 14 and 21 psi. This is in comparison to, for example, tyre pressure, which can be between 26 and 34 psi.
