Is glass harder to break under water?

As far as I remember, there is some truth behind this statement: glass is inherently extremely strong, but it is fragile in practice because of microcracks on its surface. In water, glass dissolves to some extent. As a result, microcracks partly disappear, and glass becomes much stronger (at least for a while).

How do you survive a sinking car?

Open the window as fast as possible — before you hit the water, if you can, or immediately afterward. Stay still, with your seat belt on, until the water in the car goes up to your chin. Then take several slow, deep breaths and hold one. Do not try to open the door until the water has stopped flooding into the car.

How do you break a car window from the inside?

Take the metal pegs from the headrest, jam them down inside the area where the window goes up and down inside the door panel.

Why can’t you open a car door underwater?

When a vehicle enters the water, it can be hard to open the door because of the water pressure pushing on it from outside. If you can’t open a window, calmly wait for the water level inside the car to rise so the pressure equalizes and you can open the door.

Car windows are made from tempered glass and are designed to resist blunt force. As such, pounding on a window with a blunt object may have no effect.
