DIY electrically-fired nitrocellulose flash cannon (VIDEO)

A YouTuber posted his own low-cost nitrocellulose cannon made from some copper tubing, two 6-volt batteries and other household items.

Firing momentary flaming balls of nitrocellulose– also known as gun cotton or flash cotton– which can be bought online at magic shops, the cannon is simple enough and seems pretty sweet and simple to build.

Its sure to make your inner pyro very happy.
