James of The Action Lab, who previously explained how the iOS phone app Blower was able to blow out candles using sound, attached an air cannon to a giant speaker to show how directed sound could extinguish large kitchen fires.

James was inspired by Viet Tran and Seth Robertson of George Mason University, who invented a fire extinguisher that emits low frequency sound waves.
