Air Vortex Cannon For Erbert and Gerbert's Birthday
References: candlecannon & youtube
I'm not sure what inspired this crazy thing, but it looks like a "blast"! (Ok - bad pun...) Erbert and Gerbert's sandwich shops are turning 20 this year, so they couldn't let the occasion pass by without a birthday cake. But to blow out the candles, they decided to really do it up right. They built what they claim is the worlds largest and most powerful air vortex cannon! And, as the video vividly demonstrates, it does the job well! This thing looks like pure fun! You know...I might have to build one!
