A tumble doll is an ancient Chinese children's toy, first recorded during the Tang Dynasty. It resembles a human figure and is designed so that upon being touched, it sways and then returns to an upright position. The term can also be used metaphorically to describe people who are adept at adapting to circumstances and maintain their positions of power over time, with a derogatory meaning.

Objects with a lighter top and heavier bottom are more stable; in other words, the lower the center of gravity, the more stable they are. When the tumble toy is in a vertical position and balanced, the distance between the center of gravity and the contact point is small, meaning the center of gravity is low. After deviating from the balanced position, the center of gravity always rises. Therefore, this state of balance is a stable balance. As a result, no matter how the tumble toy sways, it never falls. For example, like what we saw at the science museum.Rolling on a cone"The experiment follows the same principle. Due to the shape of the cone and the shape of the two tracks, its center of gravity decreases, but it appears to rise. This upward rolling does not match reality in everyday life. However, it is just an illusion. Upon looking at its true nature, the center of gravity has indeed decreased. Therefore, the lower the center of gravity, the more stable the object is. To increase the stability of objects in daily life, we often increase the weight below them, such as fan bases, microphone stands, and bus stop signs."

By leveraging this characteristic of center of gravity, many more things can be done.Interesting experimentExplain some phenomena. For example, you can create a weight-bearing worm; open a capsule, insert a small ball bearing, and it can roll back and forth. We often see a box placed just on the table without falling, because the end of the box against the table is where the "center of gravity" lies, so the box remains suspended.

The tumble dryer doesn’t fall down. The tightrope acrobat holds it in his hands.Balance StickAlso to reduce the center of gravity and achieve balance. 1. Mechanical principles

Common tumbler models feature a paper body with a clay base—created by filling a mold with paper pulp or sticking together waste paper to form the shape, followed by making a semi-circular clay base. After bonding both parts together, clean paper is applied to the exterior and decorated with colors. Some use wood for the base, with iron blocks and small stones fixed at the center of the bottom. There are also others...Little GourdRemove all the flesh inside, interiorfilled with leadThe "gourd" that was made;

There is more to useegg shell, small tumblers made from old table tennis balls. All these tumblers share the same characteristics: the upper part is a hollow shell, while the lower part is a solid hemisphere with a circular base. These features give them a consistent basic mechanical structure, enabling them to achieve the "stable" effect.
