Why do eggs stand up during the Dragon Boat Festival?
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.

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.
