Making paper planes
Make a paper plane that can actually fly with these easy instructions. This traditional paper-plane design is a simple paper craft for kids that will then lead to another fun activity for kids: flying a paper aeroplane.
What you need:
- 1 x A4 sheet of paper
Activity:
- Fold the paper along the width and then unfold it to create a crease.
- On one side of the paper, fold each corner in towards the center, to the point where the inside edges are even with the center-line crease.
- Starting at the very tip of the point, fold the paper over on each side so the inside edges line up with the center crease.
- Turn the paper airplane over and fold it in half along the center-line.
- Fold the first wing with the line of the fold running nearly parallel to the center-line of the plane.
- Fold the second wing the same as you did the first.
The plane is now ready to fly!
