beam's mechanical pencil gun and black hole fun's. We used to make these all the time in middle school and shoot each other in class. Just thought I'd bring some old school fun back to the adult world.
Also there's one of my favorite stingers if you really want to inflict damage.
I feel I should also put a disclaimer: I'm not responsible for any damage or injury caused by this. Please do not shoot people in the face. What you do with this is on you.
Step 1: Get things together
1 Bic mechanical pencil
1 rubber band, preferably smaller than the one I got.
Knife and/or scissors perhaps pliers.
