Stability of spin top (tippy top)

    Stability of "spin top" (tippy top)

    I'm looking for a decent discussion of the stability of a spin top (sometimes called the tippy top), which shows that the stable configuration when spinning is the "inverted" one (spinning on the stick).

    Any help would be appreciated.

    You picked the right season for that question, Easter. spin an egg.

    Tip or Egg, the physics are not that different I guess.

    Here is the abstract:

    I have a little dreidel, I made it out of clay
    And when it's dry and ready, with dreidel I shall play.
    Oh, Dreidel, Dreidel, Dreidel, I made you out of clay
    Dreidel, Dreidel, Dreidel, with Dreidel I shall play.
