How to | Pen gun

Build the most powerful pen gun with just a few items.

Stay safe and have fun!

If you decide to attempt this project, then you are responsible for your own stupidity - Try this at your own risk. There may be risks of which I am not aware. Use the proper safety equipment and have a fire extinguisher handy if possible. Do not fire the pen gun at humans, animals or property that does not belong to you.
