A pair of engineering students have figured out how to extinguish fire using sound waves.
Mind-bogglingly awesome, right?
Viet Tran, 28, and Seth Robertson, 23, from George Mason University in Virginia demonstrate their fancy new invention in a video where they blast a frying pan with low-frequency sound waves.
The invention originated as an idea for a senior research project, and has cost them about $600 so far - and a year in trial and error.
"The extinguisher separates oxygen from fuel", 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."
