This is one of those weapons you’d expect the bad guy in a movie to start laughing at, only to get his eye taken out by the surprisingly powerful miniature cannon. Although if it were a movie, it would actually kill the person, whereas this cannon probably wouldn’t go quite that far. The itty bitty brass cannon is fully functioning and can absolutely destroy a decent sized beer mug.
To work the cannon you just do the same as you would with a full-sized, everything is just a whole lot tinier. It requires a very small amount of gun powder, steel balls and a fuse. Thankfully you don’t just get a picture of the cannon, but you can watch a video of it shoot at various objects like a light bulb, an egg and a coke can. It just doesn’t get much better than an adorably miniature cannon.
