Erecting the egg
立雞蛋

In China, it is said that the egg can be set upright on the first day of the Start of Spring, Spring Equinox day and Autumn Equinox day. It is believed that if someone can make the egg stand on the first day of Start of Spring, he will have good luck in the future.
按中國民間說法，立春、春分和秋分時，雞蛋很容易豎起來。人們認(rèn)為在立春能把雞蛋豎起來的人，來年有好運(yùn)。

According to astronomers and physicists, setting the egg upright has nothing to do with time, but with mechanics. The most important thing is to shift the egg’s center of gravity to the lowest part of the egg. In this way, the trick is holding the egg until the yolk sinks as much as possible. For this, people should choose an egg about 4 or 5 days old, whose yolk is inclined to sink down.
據(jù)天文學(xué)家和物理學(xué)家所說，豎雞蛋和時間沒有關(guān)系，只與力學(xué)有關(guān)。關(guān)鍵是把雞蛋的重心移到最低點(diǎn)，握住雞蛋，盡量讓蛋黃下沉。還要挑選已經(jīng)下了四五天，蛋黃容易下沉的雞蛋。
