A recent video by researchers in Japan shows sound waves to metewrizoyn light objects, as matches, small screws and transistor. Experiments conducted by the Yoichi Ochiai and Jun Rekimoto at University of Tokyo look like magic, However actually come from a strange natural phenomenon. When the speakers are aligned with accuracy, form two sets of sound waves which pose perfectly with one another, creating a phenomenon known as a 'standing wave'. At certain points along a stationary wave, they are known as nodes, There is no net power transfer. Because the acoustic pressure of the sound waves is sufficient to nullify the effect of gravity, light objects can float when placed in the nodes.
