Astonishing video shows scientists making objects LEVITATE using sound waves

Japanese researchers have developed a method of making small objects float and move around in mid-air using sound.

objects LEVITATE

Japanese scientists have found a way to make objects levitate using soundwaves.

An astonishing video, posted online by researchers at the University of Tokyo, shows small objects floating in mid-air, polystyrene bubbles levitating in complex patterns and water droplets being trapped in the ultrasonic field.

The scientists use ultrasound to create focused standing waves, which can levitate the objects.

They use a complex set up involving four sets of speakers, which generate frequencies so high pitched they can’t be heard by the human ear.

Levitation using ultrasound has been around since 1975, but this is the first time anyone’s been able to move objects in 3D space after they’ve been levitated.
