Scientists Can Make Stuff Levitate Using Sound

This is basically like muggles knowing how to use "wingardium leviosa". Which is mind blowing.

Japanese scientists have worked out how to make objects levitate using sound.


The process is called 3D mid-air acoustic manipulation.

This is how it works.


Particles are trapped in the node of a standing wave at the focal point created by four phased-arrays.

This means that by carefully positioning speakers around the object and playing a note of the right frequency, the scientists can make a pocket of moving air that holds the object in mid-air.

Basically, it's amazing.
