Eggs - Raw or Cooked?

Items needed:
	1 Raw Egg
	1 Hard Boiled Egg
	A smooth, flat surface

Place both eggs on the table and mix them around until you are not sure which is which. Select one and place it on the flat surface. Give it a good, hard spin. Once it is spinning, quickly use your finger and thumb to stop it for just an instant and then release it. You have to be fast at this to get the best results. If you are using the hard boiled egg, once you stop it, it will stay. On the other hand, if you are using the raw egg, as soon as you release it, it will start spinning again.

Why? With the raw egg, even though you stop the hard shell, the liquid on the inside continues to spin. When you release the shell, the spinning liquid causes the shell to spin too. The hard boiled egg is solid all the way through, so when you stop the shell, you stop the entire egg from spinning.
