Answer:
iWhen we wash clothes, our hands are exposed to water for a long time. Our hands behave as a hypertonic solution and the outside of our hands behave as a hypotonic solution. Our skin behaves as a semi-permeable membrane as it is porous. So actually the water is not absorbed here just leaving and thus it shrinks.
