Ballance egg on end on winter solstice

  1. Dec 21, 2011 #1
    Well, I missed the opportunity to try this.

    Seems, within the first one two two minutes, you can balance a egg on its end when the earth is at its solar minimum called the winter solstice..the shortest day of the year.

    Now, I figure, the earths gravitational constant in relation to the sun and moon have a play in this phenomena? Anyone care to explain what is happening in this case with physics math?

    Not much to explain. That "balancing an egg at the equinox" is an urban legend--no basis in fact.

    Here's a video from Phil Plait (BadAstronomy.com) showing how he balances an egg:

    Yes, you can balance an egg on the solstice. And on the equinox. And on Christmas, Arbor Day and St. Mungo's Day. It takes a little bit of practice, that's all.
