How to make a manual gyro simple?

The manufacturing method of manual gyroscope is as follows:

1, tool material: bamboo, veneer, saw, super glue.

2, the production method:

(1) First saw a section of bamboo tube with a diameter of about 5 cm and a length of 6.5 cm, and dug a long hole with a width of 0.5 cm and a length of 3 cm on the bamboo tube.

(2) Cut a bamboo stick as a shaft, and then make two round plates with thin boards. The diameter of the circular plate is roughly the same as the circumference of the inner wall of the bamboo tube.

(3) Dig a hole in the center of two circular plates, stick it on the inner wall of the bamboo tube with super glue, and then insert the bamboo shaft into the center of the plates. Note that the lower end of the bamboo shaft is short and pointed, and the upper end is compared.

(4) Cut another piece of bamboo, drill a hole, pass a long cotton rope through the hole of the bamboo and wrap it around the bamboo stick.

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 very familiar toy for teenagers. 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.
