What is the principle of the custom of "vertical eggs" at the vernal equinox?

The custom principle of the vernal equinox "vertical egg" is as follows:

I. Principles

1 and the vernal equinox, the northern and southern hemispheres are divided equally day and night. The earth's axis is inclined at 66.5 degrees, which is in a relatively balanced state with the earth's orbital plane around the sun, and the earth's magnetic field is also relatively balanced, so the egg stands best. Note: In fact, the statement of the earth's magnetic field is not necessarily accurate.

2. There are many protrusions about 0.03mm high on the eggshell, and three protrusions can form a triangular plane. If the center of gravity of the egg passes through this triangle, it can achieve "vertical egg".

Second, the method of separating eggs in spring

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

Step 2 find support. In order to find a suitable supporting surface, we did a small experiment. We drew inkpad on the desktop, and then stood the eggs on the inkpad. You can find that an egg that can stand will have a plane at the bottom that is difficult to see with the naked eye. Once the gravity line can pass through this plane, the egg can stand up.

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 standing on 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.
