According to popular folklore, it is possible to balance a raw egg* on one end on the equinox. It was a trick my dad used to do sometimes when I was a kid. So if you have way too much time on your hands, you can spend today attempting to balance eggs on end :)
* Okay, I’ll come clean. The egg in the picture is not raw, it’s an “empty egg” where the contents have been blown out through a little hole in the bottom (I emptied several to make easter eggs, but that’s another post for another day). The hole makes it rather easier to balance the egg upright.
