During Industrial Arts class in eighth grade, we spent several weeks doing metal working, which was mainly bending and cutting sheet metal to make a tool box, I think. I spent one two entire classes making ninja throwing stars. I got away with that. I kept them in a green plastic filing box of “secrets” under my bed. I used to throw them at a board in my back yard, until the thin metal bent. 

Later, during woodworking, at the urging of another classmate who I was trying to impress, I tried to make a pipe to smoke pot. I’m sure junior high kids must attempt this all the time. The teacher apparently watched me the entire time, and busted me, very discreetly. I never got in any trouble for it. Whether he knew I was doing it to impress another student, I don’t know.
