AngelicView:What else can you think of may have been moved into place by using sound waves, as theorized by many?
From TheScientist by Kate Yandell | July 17, 2013
Researchers have discovered how to move and mix substances using sound, according to a paper published in the Proceedings of the National Academy of Sciences yesterday (July 15). The technique, which works under normal atmospheric pressure, could help researchers manipulate reagents without contaminating them and perform reactions between hazardous materials more safely, Nature reported.
The researchers were able to levitate and transport items ranging from a droplet of water to a toothpick. They did so using pairs of sound-emitting platforms and reflector sheets. Sound leaves the sound-emitting platform, hits the reflector, and bounces back in the direction it came from. At certain points the sound waves meet in such a way that they cancel each other out, forming nodes. These nodes are where…
