This is a video of Youtuber Jarius Of All discussing and demonstrating his electric powered ducted fan (EDF) jet-engine fire vortex cannon. It can spew a swirling blaze up to twenty feet thanks to "a series of powerful fans and ductwork" to burninate things at will. Obviously,I'm going to need to get my hands on one of these, then, or later that night,my fingerprints off of it. preserve going for the video.
