Science sometimes borders on the occult, and this is no exception. The work is from the University of Tokyo, and it’s much more controlled than you think. In the video below, you can see the manipulation of small particulates moving in three dimension using an array of speakers. It’s like Disney’s Fantasia, but in real life.
From the researchers’ YouTube description:
In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays.Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.
