My gums are very pink. I brush my teeth two times a day. I have very long teeth. I want to keep them all. My house has fiberglass in it.
Blankets insulate people when they are sleeping.
Carpet is so fluffy it insulates. Snow is another insulator. Some people put snow against their house to keep it warmer. Dirt is a good insulator for creatures' homes because it will keep them warm. Fiberglass helps keep it warm in your house.
