1, prepare materials
You need to prepare a square piece of paper first. It is suggested to use brightly colored paper, so that the boomerang will be more beautiful. Besides, you need a pair of scissors and a ruler.
2. Fold this paper.
Fold the diagonal of a square piece of paper in half, and then fold the two ends of the diagonal towards the center to form a small triangle. Then, the two sides of the triangle are folded in half toward the center line to form a smaller triangle. At this time, you need to use a ruler to fold the sides inward for a certain distance as the wings of the boomerang. The length of wings can be adjusted according to your own needs. When finished, use scissors to cut off the extra parts.
3. Complete production
Then fold the whole boomerang in half along the center line, thus forming a boomerang that can be thrown. You can throw it in the open air and see if it can fly back smoothly. If adjustment is needed, fine adjustment can be made according to the actual situation, such as changing the length of wings or adjusting the position of the center of gravity.
The skills of origami darts;
1, choose the right paper
Choosing the right paper is the first step to make a successful boomerang. The ideal paper should be light and flexible, so that it can rotate quickly in the air and remain stable. Ordinary printing paper is too light, while cardboard is too heavy. It is suggested to choose a paper between the two, such as colored origami or special boomerang paper.
2, accurate folding
The folding of boomerang needs to be accurate to millimeter. Every small folding mistake may lead to the instability of boomerang flight. Use a ruler, scale or other precise tools to help you complete each step. Especially when folding wings, make sure that their lengths and angles are exactly the same, so as to ensure the same aerodynamic performance on both sides.
Step 3 adjust the center of gravity
Adjusting the center of gravity is the key to boomerang flight. The boomerang with unbalanced center of gravity will deviate from the track in flight. By fine-tuning the angle or length of wings, or adding some small weight to darts, you can help you find a stable center of gravity. It needs many experiments and fine-tuning. Don't be afraid of failure. Every adjustment will bring you closer to success.
