I searched for information on the rationale behind this sudden surge of egg-standing interest - it was the spring equinox, or Lup Chun day to the Chinese. Apparently the egg standing can only be done between 12pm and 1pm of the first day of Spring.
An equinox occurs when the sun passes directly over the earth's equator. This occurs twice in a year during spring and autumn, when the tilted axis of rotation of earth is parallel to the motion of the earth around the sun. This means that the earth's axis is not tilting towards or away from the sun during these points in time, and all latitudes of earth (except the two poles) will experience roughly 12 hours of daylight. Hence the Latin term aequus (equal) - nox (night).
Perhaps some sort of gravitational force does play its role in facilitating the standing of eggs. However it would have to be very mild, or we would be having strange physical occurrence on Lup Chun every year!

Thanks for the heads up! That theory does make a lot of sense :)
