Sorvikivi fountains consist of perfectly balanced, highly polished,
solid granite spheres placed in identically matched openings carved in the bases.
The spheres gently rotate on a thin layer of water pumped up from below at a
remarkably low 10 to 12 psi.
The fountains made in Finland, are available in a wide selection
of materials, colors, and base styles. Ball sizes range from 12 inches to 5 feet in diameter
requiring only 120 to 300 gph to begin and maintain their rotation.
A 5 tonne polished stone ball slowly revolving on a film
of water only one tenth of a millimetre thick - fact or fiction ?
