Scientists Demonstrate Levitation Using Sound Waves
A group of scientists from the University of Tokyo and a team of researchers from the Argonne National Laboratory in Chicago have independently demonstrated how levitation and motion (transportation/movement in the air) can be achieved by using just sound waves.
Watch this awesome and entertaining video by the Japanese scientists to see Motional Acoustic Levitation in action
(And to learn how it works)
The following video 1 minute video is from the Argonne National Laboratory.
And below is yet another video giving a bit more in-depth, PhD level knowledge, in a way that is easy to understand
May this information serve you as it serves me to expand my mind beyond the world of limitations into the world of possibilities.
