A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...
Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie.
"We've shown that water waves can be used to precisely move floating ... or spin about and move precisely along a circular or spiral path in the patterns, deviating at most 2–4 mm from the ...
