What happens when a glass was turned upside down and pushed in a pan of water?

Question

A glass was turned upside down and pushed down into a pan of water. No water got into the galss. Why?

Answer 1

With the glass rim just touching the surface of the water, the pressure in the glass is equal to the pressure outside and the levels of water inside and outside of the glass are the same..

As the glass is pushed down into the water, the water level inside the glass will rise slightly, causing compression of the air in the glass.

This gives a pressure equal to the depth of water to which the glass has been submerged.

(For example: A 2 inch water level will be equal to a pressure of  0.07 times greater than the outside atmospheric pressure of 1.0atm, = a pressure of 1.07atm. inside the glass.

Answer 2

holding the glass upside down forms an air bubble inside the glass. The water can not enter because the air has no way to escape... tilt the glass slightly and the air escapes and water fills up to the water line
