What kinds of gyro toys are there?

Gyro is a kind of children's toys, which is generally inverted cone-shaped and made of various materials. The way to play is to wrap the gyro with cotton rope, throw it out hard, rotate around the gyro pin, and pull it out to keep rotating. As early as the Neolithic age, there were stone gyroscopes in China, and there were also records of gyroscopes in the history books of the Northern Wei and Song Dynasties. The word gyro appeared in the Ming Dynasty. Today, there are many kinds of gyroscopes, including paper gyroscopes, solid wood gyroscopes, metal gyroscopes, plastic gyroscopes, fingertip gyroscopes and so on. Let's take a look at top toys. 1. What toy is a gyro?

Gyroscope refers to a rigid body that rotates at a high speed around a fulcrum, also known as sudra, Gan Le, ice roll (gá) and beating an old cow. Common gyroscopes have an inverted cone made of wood, plastic or metal, and the front end is mostly made of iron. According to the different ways of playing, gyro nails are cylindrical, axe-shaped or pointed. When playing, the top is wrapped with cotton rope and thrown by hand.

With the evolution of the times and the improvement of science and technology, everyone's gyroscopes are also varied and varied, including gyroscopes of various materials and shapes, gyroscopes emitted by transmitters, fingertip gyroscopes and so on.

Second, the historical origin of toy gyro

Gyroscope is a toy invented by China in ancient times. As early as four or five thousand years ago in the Neolithic Age, there were stone gyroscopes. Due to the age, there is no detailed data record for further consideration.

In terms of written records, gyro first appeared in the historical records of the post-Wei period, and was called Dule at that time. In the Song Dynasty, there was also a gadget similar to a hand-twisted gyro named Qian Qian. The word gyro only formally appeared in the Ming Dynasty. At that time, Liu Dong and Yu Yizheng wrote a book called "A Brief View of the Imperial Capital", which mentioned a folk song: willow bells and empty air; Willow is alive, spinning top; Liu died kicking shuttlecock, which shows that gyro has become a popular toy for children in China.

With the evolution of time, gyroscopes have a new style and play. Many friends have played gyroscopes when they were young, and different regions have different ways of playing. For example, the way to play in Bian Xiao's hometown is to form a circle, put the gyroscope in the circle and whip it to see who can turn the gyroscope for longer.

3. What kinds of gyro toys are there?

There are many kinds of toy gyroscopes, and their playing methods are also different, which can be roughly divided into the following categories:

1, paper gyro

Hold the upper end of the shaft handle of the paper gyro tightly with your thumb and forefinger, twist it quickly, and put it on the table, and the paper gyro will rotate independently on one foot.

2, solid wood gyro

This is the mainstream gyro, which is made of wood. Generally, guava trunk, longan wood, camphor wood and other hardwoods are selected to make a gyro shape with a round top and a sharp bottom, which is polished with sandpaper, and then nails are nailed at the tip, and the tip can be knocked flat. Playing the wooden gyro is to "smoke" for fun. Let the gyro spin on the ground and whip it with a rope to make it spin.

3. Bamboo gyro

Thread the thick cotton thread through the bamboo piece and then wrap it around the bamboo handle. Then hold the thread end in one hand, pull it back, and hold the gyro and bamboo piece in the other hand and push it forward. When both hands exert force at the same time, the gyro will rush forward and make a buzzing sound.

4. Metal gyroscope

Generally made of iron, it is less than three and a half centimeters wide from the top, like a six-petal flower; Seen from the side, it is triangular and conical, with a flat upper side and a sharp lower side, about 1 cm high; When playing with iron gyro and playing games, both of them tried their best to pull each other's iron gyro into the carton. When both gyroscopes rotate and slide to the low-lying part of the carton, there will be a crisp and loud explosion. If the rotating force is large, the other one will be ejected from the carton, and the ejected person will lose.

5, plastic gyro

This kind of gyro is specially used to listen to noise. It has a hole in the hollow part and a handle at the top and bottom. The handle at the top can be used for winding rope and pumping water. Once it rotates, the hole of the gyro will make a purring sound.

6, fingertip gyro

Also known as hand-twisted gyroscopes and bobbin gyroscopes, they are mostly flat equilateral triangles with a bearing in the center and the outer edges of three corners covered with plastic or other materials. When playing, hold the central bearing with your thumb and middle finger, and then start to rotate the gyro, so that the gyro can rotate quickly at your fingertips.
