Crepes are like pancakes but they're made out of rubber instead of flour or oats! The rubber gets all mixed up with some chemicals and washed a lot until it turns into a thick sticky paste. Then it gets squished and squashed between rollers until it becomes super flat and thin like a piece of paper. That's how you make crepe rubber!
The cool thing about crepe rubber is that it's soft and stretchy, kind of like a rubber band. It's great for making things like shoe soles or the bottom of a backpack because it's bouncy and can handle a lot of wear and tear. So, next time you see someone wearing shoes with bouncy soles, you can tell them that they're probably made out of super thin pancakes!
