PS: Is that soda bottle really a better choice than a metal drink bottle? Or is the primary concern the more dangerous nature of the metal bottle if something were to go wrong?
If its just there as a demonstration of the expansion capability then ignore this.
No, its there because I'll be using a soda bottle. As for your first question, there's a reason grenades are made out steel.

But seriously, read the threads about that subject and make a good tank.
Haha, that's actually pretty funny. Bravo!
But yeah, I'm not really too worried about it. There's been a lot of "controversy" about the use of water bottles in pneumatics as of late on this forum, so I do understand your concern. I kind of want to quell some of the paranoia regarding them later this summer and do some failure testing.
Anyway, I'm 100% confident that a soda bottle wrapped loosely in denim will not hurt me if it fails at the 20 PSI that this blaster's OPV kicks in at.
