High-Power Pneumatic PenGun

About: Im just a kid who loves making anything from spud guns to electronics projects.

Hey guys, this is my first instructable so please bear with me. I recently made this video about making a pneumatic pen gun. Please enjoy a let me know what you think. :)

NOTE: This is a piston valve, coaxial pneumatic PenGun. If you want to attempt this project, make sure you're dedicated and completely understand the concept of operation. (The concept is explained in the video) For those of you who don't know what I just wrote, this aint powered by no rubber-bands :D

WARNING: This thing may be small but can pack a serious punch at high pressure. ALWAYS wear safety glasses when operating and NEVER point at any living thing. Don't shoot your eye out kid...

    Awesome!!! I made One!! My was a little bit bigger though. Mine was the size of a jumbo pencil. This reminds me of the movie Christmas story, "You'll shoot your eye out!" If this could be rated I'd give it a five star rating for maximum! Thanks!!

    Yours truly,

    hello, I'm new in instructables but I really like this kind of homemade projects, I found this very interesting and well made, but the problem is that I can't understand the complete explanation due that my english listen comprehension is not the best, because is not my first languaje, for these reason, could you make an step by step instructable? so that I can read and get a better understanding of the mechanism and making of your awesome idea.

    Wow. I've looked and looked for a simple, yet efficient explanation for the coaxial setup, and yours is the first to truly make sense. Great job! And you're actually making something cool, none of that knex mediocrity.
