This is a purely technical problem, which has nothing to do with the Dragon Boat Festival. Astronomical experts say that eggs can stand upright on any day of the year, and a stable egg can always stand upright in an environment without any interference (theoretical environment).

Ordinary eggs, double yellow eggs, native eggs and boiled eggs, no matter what kind, can be stood up. Compared with raw eggs, boiled eggs are not easy to stand up. Careful and patient people are more likely to make eggs stand up; The more impatient you are, the less likely you are to succeed.

The skill of laying eggs

Point 1: Pick eggs.

First of all, choose an egg with a big head and a small head. When laying the egg, the big head will face down, so that the center of gravity will be lower, just like a tumbler, and it is easy to keep balance.

Point 2: Find support.

Find a suitable supporting surface, do a small experiment, coat the table with inkpad, and then stand the egg on the table coated with inkpad. You can find that the egg that can stand will have a plane at the bottom that is difficult for the naked eye to see. Once the gravity line can pass through this plane, the egg can stand up.

Point 3: Keep your hands steady.

Because the position of the yolk in the raw egg will also affect the standing of the egg, the hand that stands the egg should be kept as still as possible, so that the yolk can slowly settle to the lower part of the egg, so that the center of gravity can be low enough to keep the egg balanced.
