What makes your hands prune up when soaked in water?
It has to do with the the way your fingers are made. The tips of fingers and toes are covered by a tough, thick layer of skin. When they are soaked for a prolonged period it absorbs water and expands. However, there is no room for this expansion on fingers and toes, so the skin buckles and you get wrinkles.
