Levitation is not a magic trick. It can be done through ultrasound standing wave. Watch how particles move without tactile manipulation.
This is the wonder of Three-dimensional Mid-air Acoustic Manipulation by Ultrasonic Phased Arrays, a project by Yoichi Ochiai, Takayuki Hoshi, Jun Rekimoto from the University of Tokyo.
This technology has been used to levitate small particles, water droplets and even tiny creatures. Watch and be amazed.
