This video explains how to make a paper airplane for effectively. The first step is to fold your basic piece of paper into a triangle shape. After the creases in the paper have been created you must unfold the paper again. The second step is to fold the paper in another triangle shape starting from the opposite corner. After the shape has been formed you must refold the original triangle shape of the adjacent fold. The narrator then makes the plane into a smaller triangle shape by again folding along the set lines. The last step is to fold the wings out and bend the nose under to finish the paper airplane.
