Why must a swimming pool always be full?

Why must a swimming pool be full?

To those of you out there who do not know the answer to this question, the answer is quite simple.

 

A pool must be kept full because water equalizes the pressure which means the pressure of the water is basically what keeps the pool in shape and it prevents it from cracking. Without water in a pool the entire foundation would crack, shift or cause bulging.
