Man, I’m just reminiscing about all the “dangerous” weapons we made out of just our school supplies alone.
Disassemble a bic pen, add spitballs or thumbtacks and we had a blowgun. A ruler, rubber band, and binder clip made a nice “rubber band gun”. Fold up a piece of paper just right, and you had an origami “throwing star”.
Heck, I even made a blackjack out of a sock and a few packs of “Now & Laters” one time.
I remember ALL those “weapons” from my school years. If you got caught, you GOT AN EXTRA STUDY HALL.
