I was looking online for some solution to my question, and they varied from explaining it using potential energy to pressure equalization between the floor of the liquid between the bases. I still cannot seem to find my groove with this one. Tackling the pressure explanation, someone said that the pressure on the bottom should be the same. I thought of a swimming pool example with varying depths. How does the water still find its own level in the swimming pool example even though the water pressure at the bottom of each section is clearly different?
