Acoustic Levitation – Float Things with Sound! #MusicMonday

NewImage

From Andrei Markin:

The physics gets a little complicated but the general idea is that if you take a sound wave and reflect it back into itself, this will setup a stationary wave. Somewhere along that wave there will be a condition (or several of them) where the forces are directed towards a single point, and if the acoustic power is high enough, this can overcome gravity and we get stable levitation.
