World's first 'sonic tractor beam'

A team of scientists in the UK have developed the world's first 'sonic tractor beam'

Similar to gadgets in films like Star Trek, the beam moves objects without touching them.

The tractor beam works by surrounding the object with high-intensity sound waves using 64 tiny loudspeakers.

This creates a force field that keeps the objects in place.

By carefully controlling the loudspeakers the object can be either held in place, moved or rotated.

The beam has been tested on small pea sized objects.
