Sprinkle some salt on the table first, and then gently put the egg on the salt pile, it is easy to stand the egg. If you are worried about revealing the stuffing, gently blow the extra salt particles around the egg after it is erected, so that the egg looks like it is standing on the table without external force.

Secondly, shake the egg and stand it up, so it's in the egg? Bubbles? Up, so it is easy to stand up. Put the egg gently on the table head down, calm down, be careful, concentrate your fingertips, pay attention to the fulcrum, and don't let go until it falls. Of course, it depends on some luck. Choose an egg with a big head and a small head, with a big head down and a low center of gravity, which is easy to balance. It is easier to succeed on a relatively rough plane. After giving birth to four? For 5-day-old eggs, because the yolk is slack, the yolk sinks and the center of gravity drops, which is more conducive to egg erection.

In addition, choose an egg with a big head and a small head, and lay the egg with the big head down, so that the center of gravity will be lower, just like a tumbler, and it is easy to keep balance. 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. 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.

The vernal equinox is a day with the same length of day and night in the northern hemisphere and the southern hemisphere. The inclination of the earth's axis is 66.5 degrees, which is in a relatively balanced state with the earth's orbital plane around the sun, which is beneficial to? Vertical egg? . According to the ancient legend, the day of vernal equinox is the easiest day to lay eggs. Astronomers said that according to historical records, the tradition of dividing eggs in spring originated in China 4,000 years ago to celebrate the arrival of spring. In fact, standing an egg has nothing to do with the vernal equinox, just let the center of gravity of the egg be lower than the curve position of the maximum circumference in the middle of the egg.
