Some maniacs have gone to 100 PSI and up by reinforcing the

I remember reading somewhere they test automotive tires by filling them t=
o
200 psi of water to see if they'll blow (the water apparently lessens the
danger).

(snip)

Yes, there's no danger because, being incompressible, it does not
store energy like a pressurized gas. The only stored energy with
water pressurization is strain energy in the vessel, usually quite
small. If the vessel ruptures the pressure instantly goes to zero and
the water just runs out.

Does that mean that, if I fill the juice bottle with juice, and then
pressurize the head space to, say 200 psi (or whatever it takes to burst
the bottle or cap), that the danger is less (than if I filled it purely
with gas)?

The hose is beverage hose so it seems to take 150psi without problems.
The bottle seems to take 150psi without problems and the tire valve doesn't
seem to leak from the top so I wonder what happens if I fill it to
bursting.

What can we predict will happen if I have, say, an inch or two of headspace
and I pressurize the bottle to bursting (either glass or plastic)?

I suspect the glass would be too dangerous to even try (although glass
would hold up to higher pressure ... maybe even the 800 psi of the carbon
dioxide tank???).

I suspect the bottle top will blow off the threads before the bottle
explodes or before the hose expands. The top has a brass tire valve in it
so obviously you'd want it to be aimed the other way from your face.

Unanswered questions:
Do you think the bottle will blow first or the cap off the threads?
Do you think glass will withstand the entire 800 psi of the C02 tank?
