Does a swimming pool have gravity?

Answer 1

Every thing exists under the same laws of Gravity. many things seem lighter in a swimming pool because they are relatively lighter in a heavy medium like water rather the light medium like air. Nearly every thing falls to the ground in air. however there are a lot of things that float or go up in water because they are lighter then water. this rule applies to every thing even things that sink.

Answer 2

gravity level is water (or swimming) is half as much gravity as when you're on solid ground.
