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."

    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'.
