Scientists Use Sound Waves To Levitate, Move Objects

Posted by samzenpus on from the they-like-to-move-it-move-it dept.

sciencehabit writes "The tragic opera Rigoletto may move you to tears, but here's a more literal application of the moving power of sound. Sound waves with frequencies just above human hearing can levitate tiny particles and liquid droplets and even move them around, a team of engineers has demonstrated. The advance could open up new ways to handle delicate materials or mix pharmaceuticals."

    The sound levitated the cat about 2'.

    Just play any, for example, Justin Bieber tune and the resulting sound waves instantly move me out of the room. Most commercials on TV work the same way, unless I'm in control of the remote.

    > 'people could not have moved those great big blocks such long distances!'

    I always hate it when people say this, because it instantly indicates they have no idea what they are talking about.

    I don't think *you* are implying this, I'm just pointing out how silly it is.

    Even examining the sentence makes no sense whatsoever... 'people could not have'... People *did*. There isn't any room for 'could not have'.

    Just like the t-shirt says
