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.

But magnets are just one way of achieving this – and they require the object to have a repelling magnetic force. Now scientists in Japan have shown that a similar effect can be achieved with sound.
