I was cleaning my computer when I came across with those plans for
a piston gun:
I'm guessing that the grey part is the piston and the ratio between the barrel and the comber is 1:2.

When you take a shower, you don't drain the entire water system the second you open the tap ;)

Well the whole point of the vortex cap is so you can use it in smaller applications.. but as far as making the vortex cap bigger.. I wouldnt go past 1 inch.

But that doesnt mean you cant have a larger magazine.. you just need it to adapt down to your vortex cap size.

But if you have the space ...

it can shoot a few meters, something like 25-30 feet.

This is my new mini, that works with a big spark,
It took me like a half-hour to make it, and i was really bored.
and everyone can make it, it's fun to use it because it
shoots nails very fast! :D

Details:
Chamber: a very small spray bottle.
Barrel: pen tube.
Ignition: Piezo sparker.
Ammo: nails ...
