Why don't chopsticks fall into the bowl?

Standing in a bowl with chopsticks is a superstitious practice: generally, because children have a high fever or intermittent convulsions, nightmares and other reasons, adults dip a chopstick in water and stand in a bowl with water. It is said that this can pray to the gods of the past, let the children go and bless peace.

As for whether chopsticks clamped together can stand in a bowl with water, this is physical knowledge. A pair of chopsticks are immersed in water, but they are actually stuck together by water. A chopstick is difficult to stand because its cross section is very small; A pair of chopsticks are glued together, so the cross section is large and you can stand.

Of course, this situation can't last long, chopsticks will fall down under the action of weak external forces, such as vibration, wind, loud noise and so on caused by walking.
