Tracing the long history, we found that the cultural roots of the tumbler can be traced back to ancient China. According to legend, this toy was originally used to symbolize "tenacity" and "tenacity", symbolizing the spirit that can stand up again no matter how many setbacks. Over time, people around the world began to imitate this idea to create similar toys and give them more local features.

Then, why does the little tumbler always stand back steadily? There is an interesting physics principle behind this-the distribution of the center of gravity. Simply put, because the bottom is heavy and hemispherical contact surface, when it is tilted after being pushed by external forces, its center of mass will automatically adjust its position with the change of angle until it returns to a stable state. Such a mechanism is both intuitive and interesting.
