why does water rise in a upside down container?..

Question

So imagine you are in a body of water: e.g a bath. You place a clear container in the water, like a jug, and fill it up. When you then invert the container and slowly rise it above the surface, why does the water stay inside the container until the container breaks the surface?

Answer 1

Because all the air is pressing down on the water in the bathtub in a way that it isn’t pressing on the air inside the jug. Until the pressure gravity pulls on the water in the jug is stronger than that atmospheric pressure, it’ll stay put inside the jug.
