The incredible science of acoustic levitation

This is truly an revolutionary video! Did you know that objects can be levitated and moved around in mid air, using only sound? In this incredible video from Yoichi Ochiai (YouTube Channel 落合陽一) we see the first successful attempts to acoustically levitate small objects like styrofoam balls, water droplets, matches and even metallic nuts! Perhaps one day we can even levitate big objects like skateboards or cars? What would you like to levitate with this technology?
