They say if you take a raw egg and stand it on its end, right at the moment of the equinox, it will balance, standing upright. So today at 12:26 CST, the moment of the vernal equinox, I was ready with an egg, a witness, and my camera. As the moment approached I carefully set the egg on end on a smooth topped table. I steadied it a bit, then slowly drew my hand away. Lo and behold, there it was, a raw egg, balanced perfectly on its end on a smooth surface.


Okay, okay, the egg is actually balanced on its end, but the notion that it can only be done on the equinox is a myth. An egg generally has a slightly bumpy texture which assists in getting it to stay upright. With a bit of patience, and sometimes choosing a particularly bumpy egg, one can be made to balance any day of the year. It's an old myth, and even though it's been widely explained it seems likely to persist because of the slightly mysterious aspect.

The myth is exposed at the Bad Astronomy web site. Another article about this myth can be found in the Urban Legends section at About.com. And dozens more explanations can be found by Googling balance egg equinox. Enjoy!

Wheb I was in school, we had a teacher demonstrate that one. Hadn't thought about it in years. Thanks!

FWIW, I have two blog entries up about this; one involving a Playboy bunny, and the other is a video of me standing eggs up.

If you look at the shadows on the egg carton, they look to be at a slightly different angle than the shadow of the egg. Also, in the bottom right corner of the picture is a small symbol like shape on the table, obviously the marking of a prop that someone forgot to hide. The flash from the camera highlights can be seen in parts of the egg cartoon, but why not the egg? Also, you can see the start of the dark side of the egg, presumably where the flash didn't reach, and yet, it is in view of the camera!

Nice try, but this photo is so obviously a fake.

Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.

Awesome technique getting the eggs to stand like that...
