Along with personal jetpacks for every man, woman, and child (sure, why not), levitation is one of those conveniences that sci-fi has long promised us but has yet to deliver, other than magnetically ...

A pair of researchers didn’t need a Harry Potter spell to levitate multiple objects at once. They just needed the power of sound waves. The duo started by building two arrays, each featuring 256 tiny ...

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.

Scientists at the Public University of Navarra and the University of Bristol have developed an intriguing "sound tweezer" device that coordinates the tiny mechanical forces exerted by five hundred ...

Although scientists have been able to levitate specific types of material, a pair of UChicago undergraduate physics students helped take the science to a new level. Third-year Frankie Fung and ...

Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...
