Acoustic Levitation

From the Telegraph:
Imagine how much easier life would be if it was possible to levitate objects. Maglev trains, for example, use powerful magnets to repel the carriages and remove the friction of the train on the tracks. 
... Now scientists in Japan have shown that a similar effect can be achieved with sound. 
In this video they show that it is not only possible to levitate objects in mid-air using sound waves, but also to move them around. The results can be quite artistic – look about 1 minute in to see just what is possible.
