'Pneumatic' pen gun thingie

Annoy your coworkers using a homemade air-soft pen/gun!

Step 1 Gather the parts

using 2 special pens you will have the ability to shoot little paper balls really far and really fast (ok i'm exagerationg a bit...)

Those 2 pens are really common in France (i'm French) and are both from the same brand 'Reynolds'.

1st is a ink-eraser/rewriter pen. (top one in the image) it's like 2 pens in one, White half erases, Blue half rewrites.

2nd pen in just normal ballpoint pen (nevermind the color)

ok now why these pens in particular?? because the 1st one has a little "piston" inside to separate his 2 parts and this is movable inside and makes air compression possible! tadaaaaaa! (get it?)

ok it'll be clearer later.

you also need a razor or a sharp knife and some paper.

oh, and this isn't pnuematic. Pnuematic is air powered, this just hits a shaft into something to make it move

[dooboo93]

This is kinda pnuematic in a sense. The shaft is forcing air down a barrel "air powered". the force of the air is pushing the projectile out. However there is no actual air chamber and no release of a mass amount of air at once. So I can clearly see why you would state this is not pnuematic.

Way of,f in the long-lost land of Youth, we'd construct similar firing-pieces, from clear Bic pens and orange peels.

Though these types of pens, I've Never Ever seen before, so this project may be limited to French borders. =( Or atleast, as far as Reynolds ships. lol

[Nel2006]

yeah Sorry, I thought there was some outside of France, in Europe maybe. I hope there are some French people here would can do this. France anyone?
