Stages to know if your eggs are still fresh:

– Fill any bowl with cold water and place an egg inside.  If the egg sinks to the bottom, it is fresh.

– If the egg sits at the bottom of the bowl in an angle/tilt, it is a little older but still fresh enough to eat.

– When the egg  sinks to the bottom of the bowl but stands on a point upright, it is still safe to eat. However, it needs to be cooked soon.

– When you put the egg in the bowl and it is floating on the top, it is no longer fresh and needs to be discarded.

– If your egg has any type of odd odor or color, it needs to be discarded.

The Fact Behind the Egg

If an egg sits for a long period of time, it starts to decompose. The yoke and egg whites begin to evaporate or become smaller, as water vapor and gases are released through the porous shell.  When this takes place, gases leave the egg and air enters in through the porous shell, causing the egg to weigh less. This is the reason for the floating egg.
