Aaron Dover (Michael Ashbury) - Flat Earth: Singing Bowl Water Defies "Gravity"
Dear Aaron Dover,
Fact check = You FAIL
Singing bowls do not defy gravity.
Water waves are created in the bowls due to resonance frequency.
According to the following physics research article...
Researchers map the physics of Tibetan singing bowls

Researchers have been investigating the connection between fifth century Himalayan instruments used in religious ceremonies and modern physics.
A Tibetan bowl, generally made from a bronze alloy containing copper, tin, zinc, iron, silver, gold and nickel, is a type of standing bell played by striking or rubbing its rim with a wooden or leather-wrapped mallet. This excitation causes the sides and rim of the bowl to vibrate, producing a rich sound.
The unique singing properties of Tibetan bowls were utilized as a way of investigating a liquid’s interaction with solid materials – a situation that arises in many engineering applications such as the wind-loading of bridges and buildings.
When a fluid-filled Tibetan bowl is rubbed, the slight changes in the bowl’s shape disturb the surface at the water’s edge, generating waves. Moreover, when these changes are sufficiently large, the waves break, leading to the ejection of droplets.
A similar phenomenon exists when rubbing the edge of a wine glass, which inspired the design of the glass harmonica by Benjamin Franklin. However, the Tibetan singing bowl is easier to excite than the wine glass, since its resonant frequency is much smaller.
