Our signature Granite Ball Fountains, also known as Kugel fountains, represent the pinnacle of precision stone engineering. We calibrate solid granite spheres weighing up to several tons to sit perfectly within a custom-carved base socket. Water is pumped from beneath, creating a microscopic, high-pressure layer of water that lifts the ball slightly. This aquaplaning effect eliminates friction, allowing a massive, dense stone sphere to rotate endlessly and be easily spun by the touch of a hand.
