In this video researchers have a drop of water on a flat surface and they blast the drop with sound waves. There isn't any information on how they have the speakers setup or whatever sound wave generator they are using. In any event they play various different music around the drop of water and the water moves to the beat forming peaks and valleys. It starts out with four corners of water and a center and then farther into the video the shapes that the drop of water form into become more and more complex with multiple points forming and dissolving again. The video ends with the water moving out into a line with the points of swaying back and forth.
