This is a very simple gun that you can make out of Bic mechanical pencils. Its a little different from
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

Alright you'll need:

1 Bic mechanical pencil
1 rubber band, preferably smaller than the one I got.
Knife and/or scissors perhaps pliers.

Step 2: Preparing the Pencil

This entails basically just taking off the front of the pencil.

First picture is of just the cap off.
Second picture is where you need to cut to detach the inner shaft.
Third is of the two parts you'll need. There may be a fit problem so just shave things down with the knife or the scissors.

Step 3: The Making of the Pencil Gun

Now just insert the inner shaft into the outside backwards as seen in the first picture.
Then put the rubber band around the top of the clip and the eraser.

Step 4: Shoot Things!

Now you can add rubber bands to the clip and eraser if you're worried about the rubber band staying on. I personally liked the ability to just quickly take apart and put together and never had a problem with the rubber band flying off.

Hold at the top of the clip and the eraser. Insert the ammunition at the top and fire away!

Step 5: Want to Put the Hurt On?

So is that guy across the hall annoying you a lot today? Well you could go a little pointier on him. These make cross classroom shootings hurt.

What you'll need:
Small sheet of paper.
Stapler with staples.

Just go through the pictures and there will be instructions.
