Making miniature nut drivers

[Moby Duck]

Columbus didn't need to break the egg. All he needed to do was hard boil it and then spin it. Even if started with the principal axis horizontal, the egg will soon stand up with its axis vertical. In fact, this is the non-destructive way to differentiate raw from boiled eggs.

As if I don't waste enough of my time on this wonderful website. Now I have to hard boil an egg and give it a spin to satisfy myself that this will really work. I am assuming it has something to do with gyroscopic precession but perhaps there is a simpler explanation. Can anyone enlighten me?

Couldn't wait for an answer so I Googled it as I should have done in the first place. Apparently the problem has been studied for hundreds of years and was only solved in 2002.
See the link below for a simple explanation.
