Resonant Fish Basin
Operation: Slowly and rhythmically rub the two ears on the rim of the basin with your hands. The basin will vibrate as if struck, and the water inside will ripple. With proper rubbing, water columns can be ejected. Function Overview: The exhibit consists of a replica of an ancient washing utensil called 'Yu Xi' (fish basin). When both hands rub the two ears, two vibration sources are generated. The vibration waves propagate in the water and interfere with each other, causing energy to superimpose. Therefore, these water points with greater energy jump out of the water surface. This conforms to the physical principle of resonance. Scientific Principle: Ancient washing utensil, made of metal. It resembles a modern washbasin. If the bottom of the basin is decorated with fish patterns, it is called 'Yu Xi' (fish basin); if decorated with two dragon patterns, it is called 'Long Xi' (dragon basin). When both hands rub the two ears, two vibration sources are generated. The vibration waves propagate in the water and interfere with each other, causing energy to superimpose. Therefore, these water points with greater energy jump out of the water surface. This conforms to the physical principle of resonance.
