It's always a challenge to try and make an egg stand on it's own. You can only do this twice a year; the spring and fall equinox. That is when the sun crosses the celestial equator and when day and night are of equal length. I usually can do it in a few seconds but this time it took me several tries with several eggs. This is the first time I've tried it with brown eggs. That may be or may not be the reason.
I hear one can also balance a broom. I will have to look into that and try it sometime.
