Scientists Use Sound Waves To Levitate, Move Objects 78
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'.
This has been working for years already (Score:5, Funny)
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.

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'.
