Maybe someone could make some caps with air attachments, then go to the recycle center and pick up a hundred test bottles and get some real-world numbers. I bet the 20 oz bottles would hold a lot more pressure than the 2 liter bottles. And there's also the possibility that beverage brands behave differently.
I use a CO2 bottle + regulator to carbonate water into seltzer in a plastic 2 liter bottle. I pressurize to 57psi (because I love blisteringly carbonated seltzer) and then shake the bottle for a few minutes. I'm interested in going to higher pressures to carbonate more strongly and more quickly, but I'm scared to go any higher, since if it explodes who knows where my hands would end up.
Apparently he tested 300 PSI and never made it back to share the results...
Wow, which bottles do you use!
I used an air horn for a bicycle that had a 10 oz. bottle as reservoir. The recommended fill pressure was 90 psi. It was refilled repeatedly over two summers while travelling in some fairly warm weather. No problems and no dogs.
