Levitation and Tractor Beams using Acoustic Holograms, Science Fiction becomes Science Fact.

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.
