Practice and Play of Traditional Toy Gyroscope

The practice and play of traditional toy gyro are as follows:

Prepare a paper milk box, cut off four corners, separate the four sides of the milk box, and then cut off half the length of each side.

Round corners at the ends of the four blades.

Draw your favorite color pattern on the leaves, and stick the plastic bottle cap of the same size in the center of the leaves with transparent tape, one up and one down, and the positions should be opposite.

When you turn the bottle cap by hand, you can drive the gyro to rotate, and the pattern on it will produce interesting changes.

Paper tray for making gyro:

Draw your favorite pattern or pattern in the center of the paper tray, cut the periphery into 4, 8 or 16 equal gaps, and then fold the gaps in the same direction.

Stick a plastic bottle cap in the center of the paper tray with transparent tape, and the direction of the bottle cap should be opposite.

When you turn the bottle cap by hand, you can drive the gyro to rotate, and the pattern on it will produce interesting changes.

Make gyro with origami;

Prepare two square pieces of paper, fold them into strips respectively, and fold the two ends of the strips into triangles in different directions respectively.

Align the centers of two pieces of paper and fold them together. Starting from the triangle below, fold each corner clockwise and insert the last corner below the first corner.

Drill a small hole in the center with an awl or nail, and put a toothpick through the hole, and the gyro is ready.

When you turn from the thicker end of the toothpick, the top will rotate. If the toothpick becomes loose after several turns, you can stick a piece of adhesive tape on the toothpick as shown in the figure.

Extended data:

Gyro is one of the earliest folk entertainment tools in China, also known as sudra. It is called "Gan Le" in Minnan dialect and "Jia" or "Beating an old cow" in the north. Wuqiao area in Hebei Province is called Bo. Guizhou and other places are called géluō not not. Puyang, Henan is called Delou, and Jiaozuo dialect is called Pi Laojian.

Beijing area is called "welding tip" because the welding tip has metal solder joints, and because Beijingers want their children to understand that "traitors" are to be whipped by everyone 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.

Of course, there are also some "hand-twisted gyros" that are very popular. Gyroscope is a toy that teenagers are very familiar with. Popular all over the world. China is the hometown of gyro. A stone gyro was unearthed in the Neolithic site in Xia County, Shanxi Province, China. It can be seen that gyroscopes have a history of at least four or five thousand years in China.
