Get an Egg and Spin It.
In fact, get two eggs, one boiled and the other raw, and spin them rapidly on their sides on a mirror or other perfectly smooth surface. If you pnt the palm of your hand gently upon the. boiled egg while it is spinning, ife of course ceases to move, and remains motionless after you have lifted your hand. But if you -do the same with a raw egg it will immediately begin to spin again when the hand is removed. Indeed, it is extraordinary how long you can hold your hand npon it without destroying its motion. lie reason of this is no doubt apparent The fluid within the shell continues to revolve, though the shell is stationary, while in the other case the whole egg is stopped. If you attempt to spin the egg on the mirror like a top, you will find that the boiled egg will spin for a considerable time, but the other will fall almost immediately on its side. — Pearson's Weekly-
