Why do eggs stand up during the Dragon Boat Festival?

At noon on the Dragon Boat Festival, the sun shines directly into the northern hemisphere, and the sun's gravity interacts with gravity, just forming two pulling forces in opposite directions. This force acts on the raw egg on the ground, just like a pair of invisible hands dragging the egg, so that it will not stagger and the egg can easily "stand".

The so-called "standing eggs" and "floating needles" mean that at noon on the day of the Dragon Boat Festival, eggs that are not easy to stand up on weekdays can stand upright on the ground at this time because of their extremely masculine height. Similarly, it can be proved that embroidery needles can also float on the water.

Skills of spawning:

First, to choose a suitable contact bottom, hardware is better than software, such as high-friction contact surface such as cement floor or asphalt floor, or sprinkle some salt particles on the desktop first to increase the contact area between eggs and the desktop.

Second, eggs should be placed properly. You should lift the egg with your thumb and forefinger and adjust it gently. When you feel that the vertical line of the center of gravity falls in the contact area between the egg and the desktop, the egg can stand up.
