When you think of slugs, snails, and puppy kisses, what texture do you imagine? Is it sticky, slithery, or slippery? Any way you picture it, slime is just plain icky — and a perfect forum for learning about polymers.
Imagine a plate of spaghetti. The noodles slide around and don’t clump together, just like the long chains of molecules (called polymers) that make up slime. They slide around without getting tangled up. The pasta by itself (fresh from the boiling water) doesn’t hold together until you put the sauce on. Slime works the same way. Long, spaghetti-like chains of molecules (called polymers) don’t clump together until you add the sauce – something that cross-links the molecule strands (polymer) together.
