Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.

STORY: A UK startup is using soundwaves to make objects levitate in midair. And London-based AcoustoFab says it's "acoustic levitation" is not just a neat trick. It could also have commercial ...

Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and ...

Japanese engineers have developed a new system of acoustic levitation, using sound waves from four audio speakers to suspend solid objects in three dimensional space. The system brings a new ...
