Materials Required:
l Bathtub
l Water
l Soap
Yourself
Procedure:
- The next time you take a bath, scrub yourself clean with soap, then soak in the tub for at least fifteen minutes, with some bubble bath, if you like!
- After you step from the water and dry yourself off, check your fingertips and the bottoms of your feet. Do you notice that they are wrinkled, while the rest of your skin is smooth? Do you know what causes this difference?
This Is What Happens:
The outer layer of skin on your hands and feet is thicker than the skin on other parts of your body. So, the skin on your hands and feet absorbs water and expands when it is soaked. After you take your hands and feet from the tub, the excess water evaporates into the air and carries along with it moisture that was originally in the skin. This process dries out the skin and causes it to wrinkle.
