Coooooool: Suspending And Manipulating Objects In Midair With Sound Waves
This is a video from the University of Tokyo of scientists using four speakers to levitate and move objects in midair. Unfortunately, those objects are limited Styrofoam balls, water droplets, and other pieces of barely there. I want to see them levitate a human. Or implode all their internal organs trying to. Either way, it'll be worth watching. Keep going for the video, it really is worth a peek.
