Classic mechanical gyro, made by master, handmade, unique shape design, annotation of eternal elegance, intelligence and interest

Because it is small in size, light in weight, easy to carry, varied in gameplay, and full of tricks, it can stimulate and inspire children’s interest and thinking, and promote intellectual development. At the same time, it can cultivate and exercise children’s hands-on ability. Therefore, it is not only the best gift for relatives, friends and children, but also a rare physics teaching aid.

Gyroscopes (English:gyroscope), is a device for sensing and maintaining direction, based on the theory of conservation of angular momentum. Since the advent of gyroscopes, it has become a traditional educational toy for generations. It continues to fascinate young and old alike because it seems to have mysterious forces fighting gravity. Gyroscopes are mainly composed of a rotatable rotor located on the axis. Once the gyroscope starts to rotate, the gyroscope has a tendency to resist changes in direction due to the angular momentum of the rotor. This is an excellent tool to teach the principle of gyro inertia.

Gyro technology is applied in many aspects, such as navigation of ships, aircraft and spacecraft, accurate mapping and measurement, drilling oil wells and even film production

The gyro rotor must rotate quickly to complete all kinds of actions. There are two ways to drive it. One is to use a rope to pass through the round hole of the rotating shaft and quickly pull the wire to drive the rotor. The other is to use a plastic brace to insert the plastic brace into the gear and quickly pull the brace to quickly drive the rotor

In order to ensure the longer life of plastic braces, please pay attention to the correct method of braces: the top must stand up with the big end at the top,Please note that the pulling direction and the rotating shaft should be kept at about 90 °, so that the teeth on the brace and the gear meshing surface on the rotating shaft can fully contact without damaging the brace, as shown below

For how long this gyroscope can rotate, you can watch this video. Because the rotation time is affected by many conditions, this time is only for reference (warm tip: use the pull rope to drive the gyroscope to rotate longer): http://v.qq.com/page/z/3/a/z0172eg6c3a.html (Copy and paste it into the browser address bar to open it)
