OUDF601: Acoustic Levitation

While I was researching ways to levitate the polystyrene ball, I came across this article of Japanese Scientists that Discover a Way To Levitate Objects Using Sound. 

The developers mentioned that they employ the ultrasonic speakers and you hear nothing around the device. The science behind it seems very complex and it is beyond my ability. Therefore I will stick to using the near invisible fishing wire.

Author Tim Williams wrote,

"The three Japanese scientists/engineers are from the University of Tokyo and the Nagoya Institute of Technology and the device they’ve recently unveiled uses sounds waves to move objects through three dimensional space. It uses four sets of speakers which converge their sound waves on one point that can be moved up, down, left and right using a set of controls, essentially allowing objects to be levitated and moved around. What’s better is that the sound is ultrasound so the machine isn’t even loud – it’s completely silent." (Williams, 2014)
