Sorry. I misunderstood what you were trying to say.

I am simply saying that the balls do not tightly fit into the cubic space in the horizontal dimensions
is not true. A perfect triangular mesh on the bottom layer is as tightly packed as it is possible to place spheres. Any small "slack" remaining at the edge is too small to permit the addition of any additional spheres.

Perhaps you are confusing this situation with either the one where the spheres and small in comparison to the total volume or molecular effects where the molecules are mostly "empty" at the sub-atomic level and two can occupy the same space at the same time.

In the former case, things could shift only it there is a defect in the lattice.
In the second case, Billards balls do not interact with each other in the same way that molecules interact.

Perhaps, I still don't understand. I don't see the analogy to water molecules.
