What is a booger made of ?

Have you ever wondered what boogers are made of, well I'm going to tell you?

Well first boogers are mucus. Mucus is a thin slippery, slimy material that is inside your nose.

When you inhale air through your nose it contains lots of tiny particles like dust, germs, dirt, and pollen, snot stops the tiny particle getting into your lungs so your lungs don't get damaged.

Then the mucus and some hairs (called cilia) in your nose surround the tiny particles then the particles dry up and clump together and your left with a booger.

Also a booger is a sign that your nose is working.
