This poop-powered flamethrower is like the old high school trick of using farts to light fireballs, only on a much more epic scale. The key to creating 30-foot flames from poop, apparently, is grinding the poop into a super fine powder with a blender.
Nick Klein, the guy from Arizona who made this DIY rig, used rabbit manure for his choice of flame fuel for the National Geographic show Doomsday Preppers. He made 'gunpowder' by blending the rabbit poop and created methane by mixing the poop with water. The methane served as pilot fuel while the powdered poop made the flames go huge.
