This was a headline in Science News Magazine. "A tractor beam reels in objects with sound. Ultrasound machine pulls on a target that is large enough to see." Unfortunately I am not a subscriber and could not rad the entire article.

I was hoping that someone here subscribes to SN and would be able to post more information on this experiment. I assume that since it depends on sound waves it is only good where there is an atmosphere and not in space.
