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 ...

The average Hackaday reader is likely at least familiar with acoustic levitation — a technique by which carefully arranged ultrasonic transducers can be used to suspend an object in the air ...

Levitation as a technique generally refers to engineered methods for stably suspending an object against gravity without mechanical contact, using physical forces such as electromagnetic, ...

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 ...

I talk about why it isn't intuitive how acoustic levitation works. A North Korean soldier ran for the border - then his own side shot him five times, "The line was still alive" An 800-foot tsunami hit ...
