Ceremonial Tibetan “singing bowls” are beginning to give up their secrets.
The water-filled bowls, when rubbed with a leather-wrapped mallet, exhibit a lively dance of water droplets as they emit a haunting sound.
Now slow-motion video has unveiled just what occurs in the bowls; droplets can actually bounce on the water’s surface.
A report in the journal Nonlinearity mathematically analyses the effect and could shed light on other fluid processes, such as fuel injection.
