To make a paper airplane, first, select a piece of paper that is lightweight and easy to fold. You can use a standard letter-sized paper or any other rectangular paper. Next, fold the paper in half lengthwise, then unfold it. Fold the top corners down towards the center crease, creating a triangle at the top. Then, fold the newly created triangle down towards the bottom edge of the paper. After that, fold the paper in half along the center crease, keeping the triangle on the outside. Finally, fold the wings down at a slight angle to create the airplane’s wings. Adjust the folds as needed for balance and stability. Now, your paper airplane is ready to fly!
