What thickness are you referring to?

Edit: Square inch, does this go for burst pressure also?

I just got that

ohh, ty. I have never seen one of those b4

Maybe test one until it bursts?

Now there is a goood idea

yea i was wondering what those were two i have like 5 of them i think i might use one on my nex golfball sniper im designing

I would highly advise against using one of those for a pneumatic chamber. I had one that got some nasty stuff crusted in the bottom of it, so I blew it up. I globbed epoxy all over the threads, screwed on the top really tightly, tapped a 20 foot hose into it, and pumped air in from the hose until it blew. It only took about 80 psi and shards flew all over my yard.
It'll work for a basic combustion, but I wouldn't go more high tech than that.

Where did you tap in at in the bottle or in the cap??

He did it!

Now we know we cant use em until 80PSI (well, actually BELOW 80psi introducing a safety margin)

lol


yay i get to go and get some pvc glue and pipe at home depot...yayyyyy...lol

I filled the cap in about 3/8" with epoxy, and tapped through the top of the cap.
