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?
In: Physics
Vacuum pressure keeps the water in place in a straw because it is a very small amount and weighs very little.
A pool amount of water on the other hand is very heavy and weighs more than the how much the vacuum pressure can hold up.
