Chinese singing bowl in the EXPLORA Science Center
The bronze water sound bowl bridges chemistry and physics with a hands-on experiment. Wet your paws and rub your fins over the handles. If you do it slowly and with resistance, according to Christian Huygens’ law of physics, the bowl will begin to vibrate and make the water bubble. Here, wave crests strengthen or double, while a wave trough and a wave crest cancel each other out. An electrifying experiment.
