This is what happens when you build an extremely powerful vortex cannon, loaded with "one of the most dangerous gas mixes in the world," to fire it against houses made of straw, sticks, and bricks, like the big bad wolf.
Looking at the video—filmed at 1300 frames per second—it seems like the big bad wolf would have had a chance against the three little pigs, and eat the suckers roasted in a wood brick oven, with just salt and a bit of water. If the third pig doesn't use cement, that is.
Otherwise, the 320kph cloud—which is formed by the pressure inside the air vortex condensing the water above the lake—seems powerful enough to knock down a man. Certainly more powerful than the candle cannon. [BBC YouTube Channel via Makezine]
