This egg thing has created a rough crowd. Sorry about the "Put on the Tesla
List' suggestion (although, I think the panty hose egg is the best way to
go).

Gary,

Harry Goldman tried thin-walled light-weight metal eggs
and they stood up and rotated properly.
But my solid aluminum egg didn't stand up.
I'm not sure if I made my prior posting clear about all that.  So
the conclusion seems to be that the weight of the egg and power of the
unit are the important factors.  A lightweight egg will stand up in a weak
columbus unit, but it takes a powerful columbus device to make
a heavy egg stand up.  At least this is what I conclude from what
Harry said.  I'm certainly not an expert on the subject, and I never
tried any columbus egg experiments.  Others may know much
more.
