...on the next Geraldo!


You know the kind I mean.  These little tops are spherical with a little peg 
for a handle.  When spun they spin (natch), the peg drops down to the side, 
then to the surface, and then the whole top pops up and spins on the peg 
until friction "wins" and it falls over and comes to rest.

Now, why?  My colleagues and I are stumped. We have a few ideas, but if anyone 
knows we'd appreciate some help on this.  A pointer to a journal article or 
book or somesuch would be fine.

Thanks.
