Called the shortie, its just made from the combustion chamber of my previous gun. I only had to remove the threaded endcap set and about an inch of pipe, then glue it to the tee. 2 inch barrel, bunsen burner ignitor.

Hahaha cool little cannon looks cool and everything, but i doubt that awkward looking chamber isn't helping performance any bit, but that probably wasnt the objective for this cannon anyways.

what keeps the sparker from being the projectile, and shooting you in the hand? Other than that, it looks like a cannon, though weird setup, and not to great looking ergonomics, but then again I have no idea how you would hold it, so it could work.

I'm with the other guys. A little awkward, thrown together looking. I don't much care for long nosed lighter ignition, primarily for safety reasons, but truthfully, for me anyway, it just seems the lazy way out.

Looks really tough to hold and shoot as well... Sorry, I can't find many redeeming features here.

It IS ergonomic, can be shot by one hand and most importantly, free and took less than 15 minutes. The lighter is a tight fit, and I've been using it that way since my first gun.
