Levitation By Sound Waves

This pretty cool. A team of Japanese researchers used a phased array of loudspeakers to not only levitate small objects, but move them around too. The frequency used is 40kHz, but there's no word on how much power is required.

I can just see it now, as lead singers everywhere levitate across the stage at venues near you.

Thanks to my buddy Darion Pickering for the heads up on this.
