US students invent portable extinguisher that puts out fire with sound waves

Two students at George Mason University, Virginia, have taken fire fighting to a new level with a green technology fire fighting equipment that uses only sound waves to put our flames.

Viet Tran and Seth Robertson invented a device that can put out flames using only a blast of sound.

In a demonstration video, Seth killed off leaping flames in a frying pan by blasting low-frequency sound waves t it from their portable fire extinguisher.

According to the Telegraph, Tran and Robertson say they created the green technology to stop kitchen fires and eliminate the toxic and messy chemicals used in the normal commercial extinguishers,

But they are optimistic that it could be used in wide areas outdoors, such as large forest fires, handled by robots or drones so that no human lives will be lost in fighting fires.

They are even hoping it could be used in space.
