Mat for Chinese Spouting - Resonance Bowl - Vibration Demonstration Pad - $13 - (Pinson, AL)
Mat for Chinese Spouting - Resonance Bowl - Vibration Demonstration Pad PAD for Chinese Spouting-Resonance Bowl Demonstration This pad was designed to provide a secure footing for your Resonance Bowl demostration. This rubber pad is a blue honeycombed rubbber circle measuring 7" across. Use the Resonance bowl to demonstrate the behavior of waves and their interactions. Due to the vibrations caused by the rubbing of the handles, the water surface begins 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 handle. It is believed to generate the precise frequencies needed to produce standing waves - the spouts of water rise from these waves... While it sings. It helps to have a padding under the bowl to keep it from slipping.
