It seems scientists are claiming to have proved it’s possible to levitate objects in mid-air using only sound.
As Garfield would say:
That’s ancient news, as any cat owner will confirm. Try walking up behind our sleeping moggie and dropping something heavy on the floor. Those sound waves will levitate that sucker three to four feet faster than you can blink. (She’ll probably shred you on the way down for daring to disturb her slumbers, but that’s another matter . . . )
