Acoustic Levitation: An Amazing Demonstration

0 115

Japanese scientists have released footage of acoustic levitation experiments that demonstrate the uplifting power of sound.

In this video, Yoichi Ochiai, Jun Rekimoto, and Takayuki Hoshi demonstrate acoustic levitation, which utilizes the properties of sound to cause solids, liquids and heavy gases to float. 

As shown in the video, four phased arrays make an ultrasonic focal point, which is generated at an arbitrary position.

The standing waves provide suspending force under gravity.  The potential energy distribution is generated by the standing waves.
