eli5 why can a straw carry water without the bottom dripping but not a pool?

546 viewsOtherPhysics

Essentially my question is this: if I get a straw and put it in water, I cover my thumb on the top and pull out, water doesn’t want to leave. Idk why or how but regardless.

How come this same thing doesn’t apply for a swimming pool? Like a body of water is suspended because it has a lid or roof?

I fully understand how the water in the straw works, but what is OP trying to describe with the swimming pool?
Swimming pools have bottoms, not tops…
