Snipe your friends with this little compressed-air gun! Despite her size, this little beast packs a punch! Sorry for the bad quality, I took the pictures with my webcam (The pink wall is due to the light reflecting on my red bed).

Remember: whenever using an object that shoots projectiles, DO NOT AIM AT SOMEONE'S FACE! I will not be responsible if anyone is hurt.

Step 1: Requirements

To make it, you need:

-A reynolds pen
-A reynolds Eraser/Rewriter pen

-X-acto knife (Any sharp blade will do)

-Isolating tape (Or whatever it's called)
-A Bic mechanical pen
im ordering the pen online what are they called
this thing is so small it looks a bit cute
I still don't get how it fires...
Sorry to answer 9000 years later...<br>Hopefully this will help someone else...<br>To fire it, take your brush/stick, and push the little cap found in the erasing thingy thru the barrel. I will add a schematic.
someday, i'm gonna make an instructable of a ballpen that uses only a ballpen and hands maybe a scissor too <br>
lol, ok. The schematic or even a video would/will help. :)
