How to fold a swinging dart?

The darts that can swing are as follows:

Preparation material: paper jam.

Operating steps:

1, the first step is to fold the dart. First, prepare a rectangular piece of paper, fold the rectangle in half and open it. Then cut the paper into two parts with scissors and turn it into two rectangles of the same size.

Step 2, take out the cut rectangle, and then fold it up and down again before opening it. Then divide the paper into two parts, fold it up and down, and then become the same quarter.

3. Step 3: Fold the left and right sides in half, then fold the right two corners in half, and then unfold. Then pinch the raised crease in the middle, find the triangle on the left and turn it to the left.

4. Step 4: Fold the top of the right side along the mark, and the triangle in the middle is also folded down. Then fold the crease at the lower right to the upper right so that they overlap.

5. Step 5: Fold the upper left crease to the right and the middle corner to the right. Take out the inner edge on the right and fold the outer edge in.

6. Step 6: Close the edge turned out in the last step again, insert the corner in the middle and upper part into the triangle in the middle and lower part, and also close the corner in the middle and lower part. Fold the front and rear corners of the upper end to the opposite sides respectively, and align the two sides to form two triangles. Then one of the triangles is recessed, the other triangle is turned to the other side, and then placed in this triangle.

7. Finally, the right side should also be as mentioned above. First, fold the two corners into a triangle, and then put the triangle in. Turn the other corner in and put it on this corner. Then turn over. The boomerang is folded like this.
