Mechanical Pencil Gun

Step 4 Firing Mechanism

Get the eraser shaft, and make an incision with your blade through the center of the eraser, coming from the top. You want to split it, not cut it off. Then, take the rubber band end off of the clip, and slide it into the notch you've made in the eraser.

Try blowgun darts (trim them) or wadded up pieces of paper. They actually hurt!
