Particles In Acoustic Levitation

A team of researchers in Switzerland and Japan have developed a way of levitating and transporting small objects using nothing but sound.
It is the first time that scientists have been able to use sound to simultaneously levitate several objects next to each other and move them around. Scientists Yoichi Ochiai, Jun Rekimoto and Takayuki Hoshi have released footage of their new series of acoustic levitation experiments that demonstrate the new found power of sound..See more
