    How to Fold a Paper Boat

    First, fold a sheet of paper in half from top to bottom. Next, fold the two top corners down so they meet in the middle. Then fold up the bottom strips on both sides. After that, open the shape from the bottom and press it flat into a diamond. Fold both bottom points up to the top, and open it into a diamond again. Finally, gently pull the top points apart, so your boat stands up. Now it is ready to float in the bathtub!
