Low-Frequency Acoustic Fire Extinguisher!

George Mason engineering students Viet Tran and Seth Robertson developed an acoustic fire extinguisher using low frequency (bass) sounds, and have released a demonstration video of their prototype extinguisher in use.

From CNN.com:

Boom out da fi-ya! Bass out da flames!

Firefighters may be snuffing blazes with deep-toned sound, if a new device invented by two engineering students in Fairfax, Virginia, catches on.

Viet Tran and Seth Robertson's new fire extinguisher looks a little like a conventional one, but instead of a compressed air tank spewing out chemicals, theirs has a loudspeaker the size of subwoofer drumming out sound waves.

It's not much to listen to, just a low hum, but when pointed at flames, it makes them vanish.

In a way, it's like blowing the fire out, because sound waves are basically multiple, regular blasts of air.
