In 1959 I made a glass marble gun with a 1/2" galvanized 18" long plumbing pipe with a threaded cap drilled out for a firecracker fuse. I oiled the glass marble, pushing it down into the pipe and put in a regular black cat firecracker in the other end. Mounted the pipe-gun in my father's bench vise and pointed it at a big black bible at the other end of the work table. Lit the fuse and stood back. The glass marble went clean through the 3" thick bible with hard covers. That's when I became an atheist.
Can I take shots at the bibble, instead? Would make a good target..."Hey, got it right in the Deuteronomy!"
OK, I agree with putting down the guns, far too many floating around as it is, but I'd really rather not pick up the bibble again. If ever a book was a downer it's that one!
