Why do your hands get pruney when you put them under water?!

Hands and feet have the most dead/thick skin on them ('keratin'). This dead keratin absorbs water. This absorption causes the surface area of the skin to swell, but this outer layer is tightly attached to the living tissue beneath. So to compensate for da increased surface area, the skin wrinkles. :)

This doesn't happen on other parts of da body because the rest of our body is made up of thin skin. Our hands and feet are exposed to the most wear and tear, thus have thicker skin - dead keratin. That's why.

Best answer please hehe :)

Hands absorb water and get shriveled.
