What is your estimate as to how may cans you can *ahem* Penetrate?


Well I would be thinking about 4 at first but hopefully I could ramp it up to the next level.
BTW, Could i use Glad wrap or tin-foil as my burst disk?

Does a burst disk just increase the pressure exerted on the projectile?

I might actually start to make this today.
My piston valve gun is a constant project.
Happy SPuddin'

Interesting... we get soda in glass or PET bottles here, the only stuff we get in cans is beer

I'm pretty sure that beer cans are a little thicker

A burst disk is basically just a valve that opens instantly. It doesn't necessarily exert more pressure, it just makes better use of the pressure you have. You can use foil or plastic wrap, just experiment.

I remember having that thought too, but then I realized I couldn't think of anything I wanted to stick under my avatar.

Why should they be? They have to contain similar pressures to soda cans.

It's actually Hydrostatic shock and it's a wonderful thing :D

you were probably thinking "hygroscopic", which refers to a material that absorbs moisture from the atmosphere - as opposed to what you're doing here, distributing a lot of moisture around the atmosphere hehe

Love the ammo btw!
