Stone Fountain Ball

Rolling Sphere water fountains -

Granite rolling sphere fountain/rolling ball fountain/rolling sphere fountain /floating spheres are perfectly balanced, polished stone sphere that fits into a socket carved to the exact curvature of the ball. The rolling 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 sphere and forcing it to turn gently,no belts, no pulleys, no rubber wheels.
It operates at a surprisingly low pressure,around 9 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 rolling sphere and the socket is about 8/1000th of an inch too small Any motif or design can be engraved. Has a marble ball rolling 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 .more details our main website www.waterballfountain.com
