Update: it took time. And then a quick pry with a knife. Saved the dishes. Ravioli saved too but for raccoons outside probably lol. What I learned about physics…sheesh.

Someone has never heard of Delta P.
It’s delta p and not fraction p. The difference between ambient pressure and inner pressure (at least zero) is always smaller than ambient pressure. Delta p is therefore limited.

I sadly don’t understand these units and your point is drained in it. The point I want to make is that the “force” of vacuum is limited by the difference of pressures.
You say it changes “drasticly” with area or suction but that is untrue. It changes linearly with area (not drastically) and pressure difference has a maximum. The maximum is defined by the pressure of the vacuum(=0) and the pressure of the ambient air (1 arm). Both are constant so the maximum is constant and actually not that big.

The delta P you’re talking about has much much higher ambient pressure than what is the case here.
And even underwater there is a limit to delta P.
