Comment about water pressure increasing with depth:
A push force holding up the layers the water is Pressure * Area. Between layers of water, there is the same Area. But at the boundary below the second layer, there is twice the weight as there is under the first layer. Twice the gravitational force downwards means ... you guessed it! twice the pressure!
