On the Hardware 360, a video that shows a machine that, using three-dimensional standing waves, traps materials between the waves' focal point and allows the objects to defy gravity.

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
