Me and my friend basically found out by using certain frequency of sounds with tiny speakers you can use it to levitate small objects, as you can see in the clip there are small speakers on top and bottom and when playing audio at a certain frequency that will happen. Small white balls levitate float in the air from the sound frequency waves. Science, day time, indoors, black poster board background.
