Method of making gyro by hand

The method of making gyro by hand is as follows:

1, 15x 15 hand-made paper is folded in half, with both sides folded in the middle and vertically folded in the middle. Small squares are folded into triangles and pressed down, and the other ends are also pressed down.

2. Open the four triangles and press inward to form a small square. Fold the two sides of the four small squares to the middle and flatten the front end of the triangle.

3. Fold the triangle inside outward, and fold the longest triangle to the middle.

4. Take another piece of handmade paper 15x 15, fold it diagonally, fold it at four corners in the middle, and turn the triangle outward for three times.

5. Take another piece of handmade paper 15x 15, fold it diagonally and cross it, then fold the four corners in half three times, and press the four sides in the middle.

A gyro is a rigid body that rotates at high speed around a fulcrum. Gyro is one of the earliest folk entertainment tools in China, also known as sudra. In southern Fujian, it is called Gan Le, and in the north, it is called moraing or beating an old cow. Wuqiao area in Hebei Province is called Bo. The dialect in Jiaozuo area is called Pi Laojian. Beijing area is called welding tip, because the welding tip has metal solder joints, and because Beijingers want children to understand it from an early age.

The upper half of the shape is round and the lower half is pointed. It used to be made of wood, but now it is mostly made of plastic or iron. When you play, you can wrap it with a rope and pull it hard to make it rotate upright. Or rotated by the elastic force of a spring. The traditional ancient gyro is roughly an inverted cone made of wood or iron, and the game is split with a whip. Gyroscopes emitted by transmitters have been used in modern times.
