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.

just tried it, similar to the chapGun, but the chapgun didnt leave a HOLE IN MY WALL!!!!!

 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. 

 ok, thanks

No problem.

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

Nice, this one looks realistic, that's what makes it great. When it has a hopper you can see that it isn't a pen.

I had a pen with a loose top. I was messing with the spring in history and it suddenly exploded!

that happens alot

Always fun. I used to shoot ceiling tiles with a bunch of cheap pen-ink-cartridges. Was a game with friends to see who could get the most ink on the tiles. Bonus points if you shot a trash can and knocked it down.

I have done this before excellent for shooting the ceiling at school they jab in there and stay there
