British Engineers Create Sonic Tractor Beam (bbc.co.uk)

An anonymous reader writes: According to the BBC, engineers in Bristol, England have created a system for remote manipulation of physical objects using sound holograms. The video shows pea-sized objects being dragged around and stacked up in mid-air with no visible means of support. "In essence, an object sitting in a 'quiet' region of space can be held there if it is surrounded by very high-intensity sound waves. As the pattern of that boundary shifts, the object can be moved around." If the Empire is making a tractor beam, now they only need a Death Star to go with it.

In essence, an object sitting in a 'quiet' region of space can be held there if it is surrounded by very high-intensity sound waves.

In Space, no one can hear you tractor beam.

Ah, just turn up the volume until somebody does.... My volume knob thing goes to 11! So there....
