Humans Can Be Levitate With Acoustic Tractor Beam

Scientists at the University of Bristol are claiming that they have developed a way to levitate human beings using sound tornadoes.  Video included.

Physics Breakthrough: ‘Sound Tornadoes’ Can Levitate Humans With New Acoustic Tractor Beam

Acoustic tractor beams work by using sonic power to capture particles and suspend them in mid-air, according to a press release from the University of Bristol. This gives them an edge over devices that use magnetic levitation, which can struggle to grab small or otherwise tricky objects like liquids. But they’ve only been able to capture small objects, according to CNETnever anything larger than the wavelength of the sound.

Researchers from the University of Bristol became the first to overcome that size limitation, paving the way for levitating humans. They created a system of rapidly fluctuating acoustic vortices—basically, tiny sound tornadoes, with a “twister” of loud sound surrounding an inner, and completely silent, core, according to the press release. A paper describing the research was published in the journal Physical Letters Review.
