Black Granite Fountain Ball, Black Granite Fountain Ball

Granite floating sphere fountain/ball fountain/rolling sphere  fountain is a perfectly balanced, polished  stone sphere that fits into a socket (base) carved to the exact curvature of the ball. The sphere revolves 360 degrees in all directions and actually floats on a thin film of water.
Water is pumped up from beneath the socket, lubricating the ball and forcing it to turn gently—no belts, no pulleys, no rubber wheels! It operates at a surprisingly low pressure—around 10 psi. Once started, the ball continues to turn until the water is shut off. However, even a child can stop it, change the direction of spin, and set it on an accelerated twirl.

The space between the ball and the socket is about 8/1000th of an inch—too small Any motif or design can be engraved. Has a  granite ball floating on a pressurized stream of recirculated water. This rotating globe is recommended for use in main entrances, shopping centers, gardens, etc.
It has a unique/special feature of having geometric center perfectly coinciding with the center of gravity. We can etch the map of the world or any other design on the ball as per customer requirement
