Hey, get your finger outta there! Instead of picking them out, let's learn about those little blobs. Yeah, we're talking about boogers.
To understand what boogers are, you need to know about mucus (say: MYOO-kus). Mucus is the sticky, slimy stuff that's made inside your nose, airways, and even your digestive tract. If you're like lot of kids, you have another name for nose mucus: snot. Your nose and sinuses make about a quart (about 1 liter) of snot every day.
