All about that bass: Students use sound waves to put out fire

This story could blow your mind. Two George Mason University engineering students are blowing out fires with sound waves. Turning up the bass, no treble, and drowning out the flames.

The YouTube video shows how it works. Students Seth Robertson and Viet Tran claim low-frequency sound waves in the 30 to 60 hertz range can actually separate oxygen from fuel. They're talking about the thumping bass sound you hear in a lot of music.

Tran told the Washington Post, "The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting."

Experiments and research using sound waves to manipulate fire reportedly dates back decades, but according to Robertson there hasn't been anything on the market that works.

Right now, the students are only able to put out small fires that use rubbing alcohol as fuel, but they hope their invention might one day be adapted for consumer or professional use.
