Did you know? You can't fold a piece of paper in half more than 7 times. The reason being that the surface area of the paper decreases by half each time. If you folded the paper in half 20 times, the papers height would be the same as mount Everest. 45 folds, and you would get to the moon. Even if you took a size of paper the size of a football field, you could only fold it in half 7 times, even using cranes and diggers to fold it.
