Acoustic Levitation is a method of suspending materials by using acoustic radiation pressure from intense sound waves. Two speakers are lined up in such a way that their sound waves (roughly 22 kilohertz) set up a standing wave strong enough to levitate light objects such as droplets when placed at the nodes where they may stay suspended for long periods of time! via webodysseum and wikipedia http://en.wikipedia.org/wiki/Acoustic_levitation #Acoustic_Levitation #Material_Sciences…
