A teetotum is an ancient Chinese children's toy, which was first recorded in the Tang Dynasty. It looks like a person and is made to sway when touched and then return to a upright position. The teetotum can also be used as a metaphor for some people who are good at dealing with their environment and can maintain their positions for a long time, with a derogatory connotation.
An object with a lower center of gravity is more stable, which means the lower the center of gravity, the more stable it is. When the Unstable Energetic Boy is in a vertical state in balance, the distance between the center of gravity and the contact point is small, that is, the center of gravity is low. After deviating from the balance position, the center of gravity is always elevated. Therefore, this state of balance is a stable balance. Therefore, no matter how the Unstable Energetic Boy sways, it is always not toppled. For example, like what we see in the science and technology museum.Cone rollingExperimentally, this is also true. Due to the shape of the cone and the shape of the tracks on both sides, the center of gravity is lowered, but it seems to be rising, which does not conform to the facts of life. However, it is just an illusion. Looking at its essence, the center of gravity is still lowered, so the lower the center of gravity, the more stable it is. In order to increase the stability of the object in life, we often use to increase the weight at the bottom, such as the base of the fan, the microphone stand, the bus stop sign, etc.
Utilizing the center of gravity this characteristic, can also do manyInteresting ExperimentAnd explain some phenomena. For example, you can make a centipede by opening a capsule and putting a small ball bearing inside, and it can roll back and forth. We often see a box placed on a table, but it doesn't fall because the part of the box that touches the table is the center of gravity, so the box is suspended in mid-air, but the

Commonly seen inverted dolls are made of paper and clay, which means they are created by pouring paper pulp into a mold or by gluing together used paper to form a shape, followed by making a semi-circular base with clay. After both parts are securely attached, they are covered with clean paper and painted. Some are also made with wood as the base, with a fixed iron block and small stones in the center of the bottom. There are also versions that use Little Gourddig out the inner pulp, insidelead-filledMade of" "gourd
There's still use for it.eggshellThe small unyielding men are all made from old table tennis balls. All of these have the same characteristics: the upper half is a hollow shell, the lower half is a solid hemispherical body, and the bottom is circular. These features give them a consistent basic mechanical structure, allowing them to achieve the effect of "unyielding."
