How old an egg is?? Easy formula to check it....

So by this formula you can check how much is the age of the egg after laying:
Take some water in a bowl and put egg in it, then observe following results.

1. If it lay down on bowl straight, then it is fresh.
2. If you see little uplift from back side of egg, then it is 1 week old.
3. If egg is upside down, with pointed end downward, then it is 2-3 weeks old.
4. If egg is floating on the surface of water, then it is very old, It should be rejected.
