“On several occasions, I observed the egg go through a series of tiny damped oscillations as it would find its point of maximum stability — disproving the tripod theory. I found no significant difference as to whether I sanded smooth the bottom of the eggs or not. We were able to keep one of the eggs standing from 25 September to 23 December with the momentary exceptions when it was bumped over by some significant perturbation; and I would stand it up usually quite quickly. Toward the end of the three months, it became increasingly difficult to stand up this particular egg.

I found a similar attribute with another egg. I was able to keep it standing for about three weeks; but then I could not get it to stand at all. Apparently, as an egg ages, its electron conductivity changes.

Also, I noticed that warm eggs tend to stand better than cold eggs.”
