Eggs stand on 立春

Bad Astronomy: Only on the day of the Vernal (spring) Equinox, can you stand a raw egg on its end. How it works: This has to be one of the silliest misconceptions around, and it never seems to die. Every year, without fail, some TV station broadcasts a news segment showing local schoolchildren standing eggs on end on the first day of spring. Usually, the newscaster will make some vague mention about how this works, but it is rarely specific, and never holds up to too much scrutiny. We'll talk about one typical reason given in a moment, but first, let's look at it from an astronomical angle: what is special about the Spring (also called the Vernal) Equinox that makes it different from any other time of the year?

Good astronomy: If you can stand a raw egg on end, it has nothing to do with the Equinox. http://www.badastronomy.com/bad/misc/egg_spin.html#badegg http://www.lcsd.gov.hk/CE/Museum/Space/FAQ/others/c_faq_others_35.htm
