She assembled a device with a 12-volt battery, a frequency generator, and a speaker that emits 30 pulses per second. That vibration pushes oxygen away from the flames, and the fire simply goes out in five to eight seconds.

This is very, very cool. It sounds like it's something that could eventually replace home fire extinguishers as the technology develops, but I'm curious if it could ever be applied in a bigger way for fire departments fighting house fires or even forest fires in some way. Maybe wineries out here in Napa will start placing speakers around their vines to help keep flames at bay one day.
