Why Is It So? - Season 1 Episode 1 الحلقة 1
All of the weight of an object is at its center of gravity, says Miller. However, the center of gravity is not always at a point on the object. This leads to a few amazing balancing acts based on one principle: an odd-shaped system can stay in balance when its center of gravity is below the point of support.
