Who the hell was your shop teacher?!Friends of mine made .9mm parabellum zip guns in shop class in High School. I don't care how 'smart' your gun is - the bullet's gonna stay stupid for a long time to come.
Call it a "candle holder" and anything is possible. Smooth bore, chunky aluminum, questionable ornamentation, take it home, strap some rubber bands in and BANG. Shit, one of my friends damn near bought it Freshman year because one of his buddies kept throwing a .22 rimfire at his feet to see if he could catch it just right and pop the primer. Yep. Yep he could. Funny thing is, in an era before Columbine the sound of .22 rimfire going off outside Social Studies was not cause for so much as a teacher poking his head around and wondering WTF.
