In this tutorial, we learn how to make a paper football with a $20 bill. First, take the bill and fold it in half length wise. Next, take the bill and fold one of the ends into a triangular shape. After this, fold the triangle over and keep doing this until you get to the end. When you reach the end, and tuck the flap on the end into the pocket you created. After this, you can hold the bill up with your fingers, and flick it with your other fingers. You can use any type of bill to make this, it doesn't have to be a $20.
