THICK SKIN (Amazing Science Games and Experiments)

Materials Required:

  1. Bath tub
  2. Water
  3. Soap

Procedure:

  1. The next time you take a bath, scrub yourself clean with soap, then soak in the bath tub for at least fifteen minutes, with some bubble bath, if you like!
  2. After you have stepped out of the water and dried 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 the other parts of your body. So, the skin on your hands and feet absorbs water and expands when it is soaked. After you have taken your hands and feet out of 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.
