Simple Pen Gun

There are many pen guns online. But to my knowledge, none of them can be made solely with a pen. So, I decided to create the first true "pen gun."

For this project you will need:

A pen
Tape (optional)

Disassemble the pen. Set aside the plastic tip, spring, and ink cartridge. The other parts can be saved for another project.

1. Slide the spring onto the bottom half of the ink cartridge. There should be a small lip that it will catch on. If you want the spring to stay on, you'll need to use a small amount of tape to hold it to the cartridge. This isn't nescessary, but it improves the gun.

2. Slide the cartridge and spring onto the plastic tip. To do this, you'll need to file or cut the tip slightly.

You're finished! To fire the gun, simply pull back on the base of the ink cartridge and release.

WARNING: This gun can be quite powerful. Please don't fire it at people.
