Description

The Chinese Spouting Bowl first appeared in the Han Dynasty (202 BC-AD 9). 4 “Han” dragons can be seen in the bottom of the basin, spraying streams of water up the sides of the bowl. It is said that the bowl was a kind of plaything for nobles, gifted scholars, and socialites in the Ming Dynasty. It was believed to foster happiness, prolong life, and increase strength.
Use the Resonance Bowl to demonstrate the behavior of waves and their interactions. Vibrations made by rubbing the bowl’s handles causes the water surface to ripple around the rim. Soon, water drops shoot up, quickly becoming continuous streams like tiny fountain jets. The water droplets and jets grow and diminish with each rub of the handles. It is believed to generate the precise frequencies needed to produce standing waves and the spouts of water rise from these waves.
