Singing Spring Bowl 15kg
The principle of the water spring bowl is similar to that of the filled wine-glass, which produces sound by going round its rim with your finger!
Place the water spring bowl on a support such as a leather cushion or felt support. Fill with clean water to the rim. By slowly rubbing the handles on their polished part with wet palms, first a droning sound rises, soon followed by a ruffle on the water´s surface, thereby creating some interesting patterns. When the movement of the hands is intensified, the water jumps up impressively from four points. By changing the position of the hands and modifying the pressure, a variety of tones can be obtained, which are all placed in an overtone scale and let the water spring once from four, then from six and eight points, or turned in the axis. This phenomenon is also closely related to the Chladni-discs, named after the natural scientist Ernst Florens Chladni (1756 – 1827): Free suspended metal plates gravelled with sand, which are stroked with a violin bow to create the “Chladni-Figures”. Both cases refer to the physical principle of the vibration membrane. Liquid bodies vibrate only in one direction.
