sound waves to carry particles into the atmosphere.

Shorts#Today, acoustic vortices use sound waves to carry particles into the atmosphere. In contrast to magnetic attraction or laser beams and so on, which can only attract some materials, the acoustic vortices can pick up and transfer most solid materials or liquids and even small insects without touching them or rubbing them with anything else. It promises to revolutionize transportation and medical and technological applications. To create acoustic vortices, the eminent researcher who developed the simulation, Mihai Kaleb, built a circular array of 192 loudspeakers that generate ultrasonic waves, frequencies too high to be detected by the human ear, and capable of carrying a particle up to Its diameter is two centimeters.
