Use this 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 will begin 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. An ancient experiment, this is an excellent demonstration model to use in the physics classroom.
