Sound is not often thought of as being a physical force, music may make you move your feet but no one would believe that it could lift you out of your seat. That was until this week when an international team of researchers led by Bristol University demonstrated the latest advancements of acoustic projection that is able to build acoustic holograms that can levitate objects or act as a tractor beam.
While technology that uses projected sound to manipulate physical objects has been maturing in labs for the last few decades the latest technology might just be good enough to escape the lab and actually lead to real products.

Levitation and the defiance of gravities surly bond has been a science that struggled to keep up with its own mythology, until now.
A team of Japanese researchers have this week demonstrated the first technology that not only brings the mythology of levitation to life but leap frogs it to create a tractor beam, lifting and moving objects across 3 dimensions using sound alone.
Presented for your viewing pleasure is the astounding video of acoustic levitation in action, now including tractor beam. Sit back relax and prepare to watch the future arrive, gliding effortlessly.

Levitation, the ability to defy gravities bonds has been achieved using a number of technologies, most commonly superconducting magnets. Now a team of scientists from Argonne National Laboratory have demonstrated acoustic levitation. Using nothing more than simple sound waves the device is able to cancel out gravity, for very small amounts of liquid.
Originally developed by NASA to simulate small zero g environments the acoustic levitation technology works by creating two set of sound waves (22kHz) that perfectly interfere with each other, creating a standing wave at certain points or nodes.
The scientists at Argonne have applied the technology to a mixing process when manufacturing drugs. Some drugs require mixing without touching any surface, levitation was the answer in this case.
