Pressure of water in upside down cup
We all played with a cup in a body of water, you know when you put it in water, turn it upside down and lift above the water level and the cup holds the water in, until you get above the water surface... So say you did that in a fish tank, could the fish swim up the cup, if you held it still, or is there too much pressure, and how would you measure that pressure? Please help I have no idea how to figure this out.
