Do Eggs Balance on the First Day of Spring?

There's a myth that eggs will stand on end during the Equinox.  Is it true?  Snopes says..

The Chinese are often cited as having originated the practice of standing eggs on end during the equinox. Just as the equinox symbolically restores balance to the world by signaling its rebirth after a season of darkness, the equinox literally balances the day by dividing it into equal portions of darkness and light. If the symbol of fertility, eggs, could be balanced on end during a day equally divided between day and night, this was a sign that all nature was in harmony

Nonetheless, the vernal equinox brings no special egg-balancing properties with it. Standing an egg on its end is something just about anyone can do any day of the year; the feat simply takes the right egg and a little trial and practice. Since the vast majority of people never see or try balancing eggs on their ends on any day other than the equinox, though, many of them come away from the experience believing that something special must have occurred on that particular day.
