It seems that Feng Shui Ball is a monster, with a diameter of one meter and a weight of more than one ton. A circular base with a diameter of 0.6 meters can be jacked up when the water pressure reaches 0.5 kg/cm2.
Tap water pressure reaches 2 kg, and the pressure is not a problem. As long as the sphere is processed regularly and the spherical surface of the base is closely attached to the sphere, it is estimated that there is a groove for recovering water at the edge of the base to relieve the pressure and avoid a large amount of water escaping. In this way, with a gentle push, the huge sphere can turn.
