<human>:  How do you make a paper airplane?
<bot>: To make a paper airplane, start by folding a rectangular piece of paper in half lengthwise. Unfold the paper, then fold the top two corners of the paper down to the center crease. Flip the paper over and fold it in half lengthwise again. Unfold the paper, then fold each of the outer edges of the paper toward the center. Flip the paper over again, and fold it in half one last time. Open the paper back up and make a valley fold by folding the top two corners of the paper in towards each other. Finally, flip the plane over and fold the wings down to give it a finished shape.
