The Snake's Wardrobe Switch
Why do snakes shed their skin?
Imagine you're wearing your favorite jeans, and suddenly — they don't fit anymore. Your legs grew, your waist got wider, and now the fabric won't stretch. That's the snake's problem, except the jeans are glued to its body.
A snake's skin is made of thousands of hard, overlapping scales — like roof shingles, but they're locked together. Unlike your stretchy human skin that grows with you, snake skin can't expand. It's a tight suit that never gets bigger.
