Watch sound extinguish fire

Something very surprising! Sound is used to extinguish the fire.

By separating oxygen from the fuel, they managed to impede the fire from spreading…

This could be very useful in places where water is unavailable or difficult to access.

Congratulations for this invention!

Here’s how:

By blasting a flame with low-frequency sound waves in the 30 to 60 hertz range, the extinguisher separates oxygen from fuel.

“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,” Tran told the Washington Post.
