Eggs--how to tell hard-boiled from raw

This happened this past Easter, but if you ever find yourself wondering whether the egg is hard-boiled or raw, here's how to tell the difference:

1)   Turn the egg on its side.  Lay on a hard surface like the counter or cutting board.
2)   Using your index finger and thumb, spin the egg.
3)   If the egg spin quickly and evenly, it is cooked.  If it spins slower and wobbles a bit, it is raw.
