Introduction: Pen Gun

This Instructable will show you how to make a pen gun that is extremely simple it took me 2 minutes to make it also looks purity realistic

Step 1: What You Will Need

what you will need is
a knife
and a pen

Step 2: Building

First take the guts out of the pen but don't throw them away then take you're knife and cut about 4mm away from the pen enough to slip the ink thing through the bottom.

Step 3: Building

Now take the spring from the ink thing and put the spring on the other side of the ink thing now slip it down through the top of the pen and through the hole you cut now pull back on the ink thingy and release the ink thingy and should go flying.

     That means that you made it right.


     Try filling the pen with commpressed air and a tiny valve. I filled one to 350psi, then i shot it. KABBOOOOM!

     simple, but its very weak, it only goes about 3 feet is there anyway to make it stronger?

    Yes stretch the spring a little and make sure the pen ink thingy runs smoothly in the pen. 

    cool you should make an Instructable on how to make it.

    Once I made one that shot the tip of the pen off... Then I lost it.
