Vortex Cannon packs quite a punch

Forget about the Big Bad Wolf trying to huff and puff away to blow down the three porkers’ straw house – all he needed was this nifty looking vortex cannon. This version that was built by the good folks over at BBC pack quite a punch, and when you see a smoke ring shooting out of its barrel, it is actually a ring shaped cloud formed by condensation in the rapidly moving gas that travels at around 200 miles per hour, knocking down a whole lot of things in the process. We’re still waiting for a battlefield vehicle like the Sonic Tank from the world of Dune.
