I found instructions online about how to make a pen gun with just the pieces in the pen, and I'm going to share my modification that will let you keep track of all of the pieces.
Note! I am not responsible for any damage to you, your property or other people. Be smart, and don't aim at the face!

You'l need:
1 pilot g2 pen

1 cheap pen ( the non-retractable, give away style pens)

1 paperclip
Small ammo


1.) Take the ink out of the cheap pen and cut id down to around 2 inches. make sure your ammo can freely pass through the small section!

2.) Disassemble your pilot pen. use the ink cartrige to push out the back, and unbent the paperclip to take out the spring.

2.5.) Now you need to know the parts. The tip is the front half of the pen. you don't need it to use the gun, but you do need it if you want to keep it as a working pen. The cheap pen part is the barrel. It keeps all of the parts securely in the chamber, or the back half of the pilot pen. In the back of the pilot, you'll see two parts. the part you push is the trigger, and the other, smaller part is the bolt. the spring is the power, and the ink cartrige is the ramrod.

3.)Put the trigger down the chamber, then the spring, then the bolt.

4.) push the barrel into the chamber. if it doesn't stay, try wraping some electrical tape around it.

Fire!) put your ammo down the barrel, and push it down with the ramrod. take aim, and push the trigger to fire! Don't shoot at your teacher though...

This doesn't shoot that far, but it still shoots a small distance. Hopefully more office weapons soon!
