Erecting the egg

豎蛋

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.

中國(guó)有個(gè)民間說(shuō)法，雞蛋在立春、春分和秋分節(jié)氣的第一天可以豎起來(lái)。據(jù)認(rèn)為，如果一個(gè)人能在立春日這天把雞蛋豎起來(lái)，他就能交好運(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.

天文學(xué)家和物理學(xué)家指出，雞蛋豎起來(lái)和時(shí)間無(wú)關(guān)，和力學(xué)有關(guān)。最重要的是把雞蛋的重心調(diào)整到雞蛋最低的部位。訣竅就是握著雞蛋，直到蛋黃盡可能下沉。人們應(yīng)該選擇一個(gè)放置了4到5天的雞蛋，這樣的雞蛋蛋黃容易下沉。
