Paper money gets wrinkled because it’s touched by a lot of people. Every time someone holds, folds, or drops the money, it changes shape, like when you crumple up a piece of paper and then flatten it again. Over time, those little changes become big wrinkles.
Examples
- A dollar bill gets wrinkled when a kid folds it to put in their lunch box.
- Your favorite $20 bill has wrinkles from being used at the grocery store every week.
- When you drop your wallet on the floor, money inside gets crumpled.
