Engineers from The University of Tokyo and The Nagoya Institute of Technology, have recently introduced a three-dimensional mid-air acoustic manipulation device. The device uses only sound waves to actually levitate millimetre-sized particles and move them three-dimensionally. Surprisingly, the process is absolutely silent as the device uses ultrasonic speakers.

Brusspup is back with even more amazing resonance trick, called the Chladni plate experiment. This time the guy attached a tone generator to a black metal plate and poured sand over it. As the sound frequencies from the speaker make the plate vibrate, the sand gravitates to those areas where there are less vibrations, and creates complex sand patterns. These patterns are never random, and get more complex with the higher frequency.
We already wrote about Brusspup and his crazy anamorphic illusions – and now he’s back with new tricks! This time he attempts to bend water using an audio speaker set to produce a 24hz sine waves. His first video, testing the principle, made it look as the water was going upwards, but now Brusspup has taken it up a notch and actually makes the water flow in shapes and patterns!
