Nitrocellulose is just a fancy word for flash paper. But Youtuber NightHawkInLight has created a pretty simple cannon that he used to fire this flash paper. It’s all bark and no bite, but that show is pretty impressive, as is the video below. The entire cannon is very well made, especially the curved hinge. Actually, everything this guy is doing looks professionally made. I’m not sure I would have the wires as exposed as that, but hey, it’s not going on my desk.
