Here is a video of Julius Sumner Miller's show illustrating Pascal's principle: https://www.youtube.com/watch?v=8ma4kW3xVT0
At 12:31, he states (but only sort of demonstrates) that a glass bottle completely filled with water would be able to act as a hammer, meaning he could hit the screw and the bottle would not break.
My confusion is that, according to Pascal's principle, hitting a glass bottle with a nail like Julius did would essentially be equivalent to hitting the bottle with the same nail everywhere from the inside. That would certainly shatter the bottle.
I'll provide my explanation of this (I'm probably wrong): The internal pressure of water at ~20 degrees Celsius is much less than atmospheric pressure. This means that a closed, glass bottle filled completely with water has a net force going inwards. Water can not compress, and so the pressure the water exerts on the glass bottle increases until it is not enough to deform the glass bottle. Thus there is a net force inwards on the glass bottle system which is the very lowest amount at which glass will deform.
When the glass bottle is hit by a nail, it deforms, applies a force to the water over some area, and by pascal's principle, this same pressure is applied everywhere throughout the glass bottle. However, because there is already net force inwards from the atmosphere and the water's pressure, the glass bottle does not feel a sufficient net force outwards to shatter it. Essentially, the atmosphere cushions the blow outwards that the glass bottle would otherwise feel from the water's application of outwards pressure.
Is this correct, or grossly misguided?
Edit: Another explanation I can think of is based on how the glass deforms. If, for example, the glass deformed by having the half of the surface of its cylinder deforming inward, then this would imply a relatively large force over a relatively large area, which diminishes the pressure exerted by the water outwards greatly.
