> What is the physical principle that makes the water come out of the tap? How do they make it come out?

Curious coincidence, I was literally thinking yesterday: “but why does the water come out of the tap?” I self-answered “must be the pressure somehow” but did not dig much more…



The water gnomes carry it there.


Water is pumped to a water tower which is up high. From there it's just gravity plus siphon type effects.
