The FLOAT Test
Eggs are good when:
Fill a bowl with water.
Place the eggs in a bowl so that all the eggs are submerged.
If the eggs settle to the bottom and lay on their side...they are as fresh as can be and yolks do not need to be thoroughly cooked.
If the eggs, while still on the bottom of the bowl, start pivoting upward they are a little less fresh but can still be used for baking, scrambling..

When completely upright but still on the bottom of the bowl...the egg is still ok but must be thoroughly cooked (scrambling, used in batter for frying..)
Once the egg starts to float and is no longer in contact with the bottom of the bowl...discard it!
When things spoil, they oxidize; this may explain why the egg floats;)
