How to make a little gyro when I was a child?

When I was a child, the little gyro did this:

1. Prepare a slightly larger bottle cap and wash it for later use.

2. Press the bottle cap on the cardboard and draw a line along the bottle cap with a colored pen.

3. Cut out circular pieces of paper along the line with scissors. Cut out other sheets of the same paper in the same way.

Apply glue between these pieces of paper and stick them together.

5. Draw your favorite pattern on the top layer with colored pens. Punch a hole with a needle. Pass the stick through the hole and make sure that the length below is longer than that above. The delicate little gyro is ready.

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.
