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?

If the water lowered, it would dramatically lower the pressure inside the container, effectively sucking the water up. The water outside the container is under one atmosphere of pressure, and that pressure applies to the entire volume of water, so the water in the container is is under one atmosphere of pressure too, and so is the air in the container. If you pull the container up faster than the water can rise, you’d have the same amount of air but a bigger volume – a lower pressure, which the water will shove up into until it equalizes
