Inspired by the fireball throwing capabilities of Pyro in the X-men, Everett Bradford has designed a similar system that mounts on the wrist and propels fire with a backward palm jerk. The flame gets ignited through a fuel can on the waist. This system indeed looks like that of a superhero but could prove fatal if there’s even a slight leakage in the fuel pipes. The combustion mechanism is rather complex and enthusiasts could take a look at the second video for a detailed explanation from the inventor himself. But I do recommend, DON’T TRY THIS AT HOME!
