Think of the _ _ lls it took to pour explosive powder down a metal tube, then stuff a round pellet down on top of it, and then close your eyes, strike that kitchen match and light that wick. Proof that we had rednecks amongst us before we knew what it meant.
I'd love to have seen the expression on that dude's face the first time that explosion/projectile went off down the barrel!! I can just imagine him (or her!) saying..."Hey Ya'll, you ain't gonna believe this s- - -!!!" I bet there were plenty of singed eyebrows!!!!
