The Ultrasonic Levitation Machine

sonic_levit

The Ultrasonic Levitation Machine levitates objects in the air. Levitating objects with sound can be done by aiming an ultrasonic sound beam at a reflector. With a little adjustment, the desired standing wave as shown in the illustration can be achieved. This Sonic Levitation Machine here on Kickstarter produces an ultrasonic wave of 28,000 cycles per second with a wavelength of 12.14286 millimeters. It uses up to 70 watts of power to produce an intense sound wave powerful enough to levitate objects.
