How about Diabolo in physical education class's freshman year? Is it better? Have you learned anything?

The selection of diabolo is good, but it is difficult. I've learned it.

Diabolo, called Hu Knock, Empty Bell and Empty Zheng in ancient times, commonly known as buzzer, bell, bell, old cow, stuffed gourd, wind gourd, ringing gourd and Lei Gonggong, belongs to traditional toys of Han nationality.

Typical diabolo can be divided into single wheel and double wheel. Two-wheeled diabolo is shaped like a waist drum, made of bamboo or wood, with two flat round wheels at both ends. The wheels are hollow, with four or five small holes dug in them, bamboo flutes placed in the holes, and the two wheels are connected by shafts. A single-wheel hollow bamboo is shaped like a top with wheels on one side. Because of its hollow wheel and bamboo flute, it is named "diabolo".

origin

Diabolo has a long history in China. According to textual research, Diabolo was first evolved from the Han folk game equipment "Gyro". Gyroscope is a toy that appeared in ancient times. Wooden gyroscopes were unearthed in Hemudu Cultural Site and Changzhou Weidun Site in Neolithic Age, while ceramic gyroscopes were unearthed in Yin Xi Village Site in Xia County, Shaanxi Province.

Later, in order to prolong the rotation time of gyroscopes, people beat these wooden or ceramic gyroscopes with whips; Later, a bamboo gyro was used, and the air was used to blow the whistle on it, which is the "sounding gyro". Later, "singing the top" gradually became another name for "diabolo".
