YouTube’s ScienceBob somehow managed to get his hands on 315 small plastic containers that once held something called “photography film.” So he did what any mad scientist would do with such a windfall: use them to build an ethanol-powered, Tesla coil-triggered gatling gun.

The weapon won’t strike fear into anyone’s heart, but any opportunity you get to play with a Tesla coil is obviously time well spent. Besides, what else are you going to do with film canisters in the age of digital photography?
