Scientists have now levitated small live animals using sound

Wow the dawn of a new sport levitating animals. I thought levitating beings with sound happened automatically at heavy metal concerts anyway.

Scientists have now levitated small live animals using sounds that are, well, uplifting.

In the past, researchers at Northwestern Polytechnical University in Xi'an, China, used ultrasound fields to successfully levitate globs of the heaviest solid and liquid—iridium and mercury, respectively. The aim of their work is to learn how to manufacture everything from pharmaceuticals to alloys without the aid of containers. At times compounds are too corrosive for containers to hold, or they react with containers in other undesirable ways.

"An interesting question is, 'What will happen if a living animal is put into the acoustic field?' Will it also be stably levitated?" researcher Wenjun Xie, a materials physicist at Northwestern Polytechnical University, told LiveScience.

Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.
