Eggs have an air cell that becomes larger as the egg ages and acts as a buoyancy aid. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is older, but it may be perfectly safe to use.
Are eggs bad if they float in boiling water?
To perform the float test, gently set your egg into a bowl or bucket of water. If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air.
Why is my boiled egg floating?
If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy. However, an egg that floats may still be safe to eat.
Is a floating egg bad?
This is not a myth; fresh eggs sink while bad eggs float to the top. Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base.
How do you know if an egg is bad after boiling?

Do floating eggs work?
If an egg sinks to the bottom of a bowl of water and lies sideways, it is very fresh; if it stands on one end in bottom of the bowl, it is less fresh but still good to eat. But if it floats to the surface of the water, indicating that air has permeated the shell, it is no longer fresh.
What does it mean if an egg floats?
An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is old, but it may be perfectly safe to use. A spoiled egg will have an unpleasant odor when you break open the shell, either when raw or cooked.
Can you eat 2 week old hard-boiled eggs?
Kitchen Fact: Hard-boiled eggs can be stored in the refrigerator for up to one week. Hard-boiled eggs, peeled or unpeeled, are still safe to eat up to one week after they were cooked.

Does an egg float in soap and water?
Because the egg is more dense than the water, the egg pushed away water particles so it could make space for itself, thus sinking. This makes salt water denser than regular water. The denser the liquid, the easier it is for an object to float in it.
What will happen to the egg in the glass of water if you add salt on it?
An egg floats in salt water because the mass of the salt water displaced is equal to the mass of the egg. The egg’s density is less than the density of the salt water. When an egg is placed in fresh water it immediately sinks to the bottom of the container it is placed in.
