Candle Cannon
The geek in me would be remiss if I didn’t post this video of the Candle Cannon, the biggest air vortex cannon ever created. Marvel and enjoy.
The Candle Cannon: Behind the Scenes movie is also excellent. And for a small dose of air-vortex humor, there’s a short rendition of the Three Little Pigs, which, it turns out, is about 1/3 the length of the real story.
