Question

why does the skin of your fingers shrink when they are in water for a long time

Answer 1

Our skin is porous and behaves as a semi permiable membrane. When we wash clothes, our hands are exposed to water for a long time. Our hands behave as hypertonic solution and the outside of our hands behave as hypotonic solution. ... The water is not entering your hands, it actually leaves them and hence, they shrink.

Answer 2
