Water in a swinging flow
The special form of these bowl make the water, which is pouring into them, swing. It swings and forms an “eight” shape, as a wave which flows alternately to one and the other wing of the bowl. This movement is not only magic for the viewer, but it also stimulates the capability of water to clean and regenerate itself.
It corresponds to the natural flow of water, which moves vibrating into the shape of meander.
