Talk:Tesla's Egg of Columbus
This experiment is not what it appears.
If you take a regular hard-boiled egg and spin it on it's side, it will roll up onto the pointy end of the egg and spin just like Tesla's egg did...but minus all of the coils and other junk.
I think, therefore that all this complicated apparatus does is to start the egg spinning - the standing-up-on-one-end part is an unrelated thing. This PDF:  explains how this happens (in relation to a toy called the 'tippe-top', which does a similar thing when you spin it).
