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.

Sound! It’s a thing you hear, moreso than something you see with your eyes. And yet, it is possible to visualize sound with ...

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 ...

NYU researchers created a new type of time crystal suspended in mid-air Sound waves move floating beads in rhythmic patterns, defying basic physics. The experiment reveals motion and energy transfer ...
