As disgusting as it might sound to some people, let's make some fake snot! Snot actually serves an important purpose in our body so this experiment is not all about grossing out our friends, although that's certainly part of the fun.
What you'll need:
Mucus is made mostly of sugars and protein. Although different than the ones found in the real thing, this is exactly what you used to make your fake snot. The long, fine strings you could see inside your fake snot when you moved it around are protein strands. These protein strands make snot sticky and capable of stretching.
