We all know how regular fire extinguishers can put out a fire. But there are other ways to fight fire. George Mason University Engineering students Viet Tran and Seth Robertson have invented a new fire extinguisher that relies on low-frequency sound waves to get the job done.

The device is free of toxic chemicals and can be mounted on drones to improve safety for firefighters. The prototype weighs about 20-lb. What do you think? Are you impressed?
