[net.physics] eggs @ equinox

toh@u1100a.UUCP (Tom Huleatt) (04/18/84)

until, just as suddenly, it disappeared.   :-)

A friend told me that for a certain time (hours, I believe)
during the spring or fall equinox, raw chicken eggs can be 
made to stand on their ends.  She said that she had tried
it once, and that it had worked!

Does anyone know if this is true, and if so, why?

    Some raw chicken eggs can stand, some can't.  It doesn't matter
what time of year it is, the only things that matter are the shape of
the egg, its surface roughness, and how fresh it is (stale eggs lose
water to evaporation through the shell, lowering their centers of
gravity.  Stale eggs also tend to have more flexible yolk sacks,
allowing the heavy yolk to slouch lower in the shell, again lowering
the c.g.)

                From an egg stander in good standing:

I heard of a news item about the equinoctial egg effect this past
equinox. Somebody in New York put on a demonstration or something.
The idea, to repeat, is that eggs will stand on end more easily for
some few moments around the equinox.

I feel competent to state that there is absolutely no physical effect
which is even a candidate for explaining such a phenomenon. If I'm wrong
it won't be the first time I got egg on my face, but I think this one
can be classified with the razor sharpening pyramids.

And then there's the old parlor trick of getting an egg to stand up
on the WRONG (narrow) end!

The trick is, you spill a SMALL amount of salt (or sugar or dirt)
on the table, stand the egg up in the salt, and blow the excess
salt away. Generally this will end up leaving only the 3-4 grains
of salt that are actually holding the egg balanced, so you can pick
up the egg and give it to someone (saying, "Here, YOU do it!"), and
no one will ever see the salt.

(Hmm... is there more salt in the air at equinox??? ;-} )

Actually, the news story I saw claimed that it worked only on April 1.
