On May 2nd, according to reports from several domestic media outlets, a cute child recently punched a wobbly toy, but to their surprise, it didn't bounce back, leaving the child puzzled and turning their head in question.
Witnessing this scene, netizens commented: "This little one has a big question mark in their tiny head."
It is understood that the principle behind the wobbly toy's ability to stand upright without falling lies in the concept of being top-heavy and bottom-light, meaning the lower the center of gravity, the more stable it is.
When subjected to external force, it loses balance, but once the force is removed, the wobbly toy can return to its balanced state on its own.
For instance, experiments like the "rolling cone" we see in science museums operate on the same principle. Due to the shape of the cone and the tracks on both sides, its center of gravity is descending, although it appears as if it's ascending, contradicting what we observe in daily life.
However, this is merely an illusion. Once we understand its essence, we realize that the center of gravity is actually lowering, hence the lower the center of gravity, the more stable it becomes.
In daily life, to enhance the stability of objects, we often add weight to the bottom, such as the base of an electric fan, microphone stands, or bus stop signs.
