Scientists use sound waves to levitate, manipulate matter (+video)
A team of scientists in Zurich, Switzerland, have developed a method of acoustic levitation that allows them to float objects next to each other and bring them into contact.

Held aloft by sound waves, a water droplet and a piece of sodium metal waltz to Johann Strauss's 'Blue Danube.'
Using ultrasonic waves – that is, sound waves whose frequency is too high for humans to hear – scientists at the Swiss Federal Institute of Technology in Zurich have made water droplets, instant coffee crystals, styrofoam flakes, and a toothpick, among other objects, hang in midair, move along a plane, and interact with each other. It is the first time that scientists have been able to use sound to simultaneously levitate several objects next to each other and move them around.
Research published in the Proceedings of the National Academy of Sciences describes how objects placed between two horizontal surfaces, the bottom one emitting high-pitched sound waves and the top one reflecting the waves back, can be levitated and manipulated.
