Well, it’s hardly surprising, given that you can (with a little effort) stand them on end pretty much every day of the year. But today’s Astronomy Picture of the Day features Bad Astronomy’s Phil Plait demonstrating that egg stability seems to be unphased by changes in the seasons.
Still, today marks the beginning of fall. If I was in someplace that actually had seasons, I’d be watching the leaves turn. No such luck.
Addendum: Bad Astronomy has a blog too.
