I'm glad to say that a large majority of my school knows what a spudgun is and has seen it work. Although, I caused them (or, in essence forced them) to know what it is. I am in a boarding school so I fire my cannon on the weekend. Also, I did my science project on spudguns, so at least ten people (if they were paying attention) knows what propane metering is and how a piston valve works. I bet they forgot though.
The thing that really gets to me though is not the people who ask foolishly how it works or for plans, but it is the people who say: "Dude, that's crazy. Hey, lets shoot it at someone!" Sure, stand over there for me.
Most elite and intellectually astute individuals around huh? I like the sound of that. Elite Spudgunner and Intellectual, yea.
