Levitation

Levitation With Sound!

"Turns out, all acoustic levitation requires is blasting out sound at extremely loud levels (160 decibels – the deafening sound of a rocket launch) at a high enough frequency (24,000 hertz – the frequency of a dog whistle) that the human ear can’t detect. When those two conditions are met, some fascinating things start to happen."
