However, birds that lay eggs on the ground, sometimes even relocate the nest, moving the eggs by making them roll. In this case the egg-shape can actually prevent eggs from rolling down a hill. | |

| Nov 4, 2012 at 1:52 | comment | added | Will Jagy | In the ballpark: my father asked once what would happen if you took a bowling ball but installed a steel weight off center, so it was still a sphere outside but the center of mass was off. And then rolled it down a hill. Evidently my brother and I missed the point, as neither of us guessed that it could jump off the hill if rolling fast enough. | |
