<human>: I need to know how to make a paper airplane.
<bot>: 
1. Start by folding the piece of paper in half lengthwise.
2. Fold each side of the paper in half again, creating four equal triangles.
3. Unfold the paper and fold it in half horizontally so that you have two layers.
4. Turn the paper over so that one layer is facing up and then fold both sides in towards the center crease.
5. Fold the top two corners downwards until they meet at the center crease.
6. Flip the plane over and bring the bottom corner up to the top edge.
7. Fold the plane in half from the top edge to the bottom edge.
8. Open your plane back up and fold the wings down along the center line.
