The secret of Tibetan singing bowls, scientists uncovered (video)

Tibetan Singing Bowl - which came from the ancient Tibetan musical instrument, the scientists revealed their secrets. Physicists realized how sound bowls and what they do with the water.
Tibetan bowls, an ancient musical instrument used in Asia for religious ceremonies and meditation, has attracted the attention of American scientists. As sound instruments and how they interact with the water, discovered physics at the Massachusetts Institute of Technology (MIT).
Usually singing bowls are made of bronze, which structure includes copper, tin, zinc, iron, silver, gold and nickel. Leading edge of the cup on a wooden pestle skinned, musician draws from the bowl thick, filled with overtones of sounds. These acoustic properties bowls scientists decided to use to study the interaction of solids and liquids.

High-speed photography has shown how sound vibrations give rise to the bowl wall surface concentric waves. But the most interesting thing was observed with increasing amplitude. At a certain intensity of sound waves on the surface of the water begin to break up, and fly up into the air hundreds of small droplets. This levitation is stable, and the drops can do for a long time in the air and move along the surface. Similar effects can be seen with a glass of wine.

Physics mathematically describe the phenomena occurring on the surface of the water, and calculate the parameters that affect the onset of levitation.

These data may be useful for calculating wind loads on structures and bridges. "Despite the fact that the system demonstrates the interaction of a solid with a liquid, we rather motivated curiosity, rather than the possibility of engineering applications. Anyone can get a new surprise, changing the properties of the liquid or the cup, "- said John Bush, author of a paper published in the journal Nonlinearity (« nonlinearity ").
