Is it true that rice sticks are mentioned in Nuo culture?

Of course it's true, it's not witchcraft, but it has scientific principles:

When the wooden stick is inserted into the rice, a squeezing force is formed among the wooden stick, the rice and the barrel, and a strong mutual friction force is formed due to the small mouth of the rice container, so that the barrel will not fall. The principle is the same as the expansion screw used in our life, which is to make the three stressed parties form friction self-locking, and then achieve the fixed effect.

Note: Insert the thin stick into the bucket full of rice until it can no longer be inserted. At this time, you can easily lift rice several times your own weight by picking up a wooden stick. Of course, the container for rice can't be a big jar. If you use a thin wooden stick such as chopsticks and a drink bottle filled with rice, the capacity of the bottle is 2 liters, and the weight of the bottle filled with rice is about 2kg. According to the experimental steps, insert the wooden stick into the rice from the bottle mouth until it can't go any deeper. After that, you can easily raise 2 Jin of rice.
