You may be able to see discoloration and mold spots within the egg. Rotten eggs or eggs that float in the water are not good for human consumption. As more air enters the egg the air pocket grows larger making the egg more buoyant.
The tilting is caused by air pockets in the eggs that increase in size over time as fluid evaporates through the porous shell and oxygen and gases filter in. It is a myth because if liquid matter changes into the gaseous state the mass of the egg will remain the same. Its density becomes lower than water.
If the egg sinks it is fresh. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. Eggs dont just float or sink during the egg test.
Generally fresh eggs will lie on the bottom of the bowl of water. But an egg has a lot of protein and calcium. A bad egg will have its egg whitealbumen be less present the egg yolk will not hold together as it will start to break down and become watery.

Some people say that rotten eggs float on the surface of the water because the liquid matter inside the egg changes into the gaseous state. Eggs that tilt so that the large end is up are older and eggs that float are rotten. Give the egg float test a tryhere are three possible outcomes.
Just fill a bowl with cold water and place your eggs in the bowl. To determine if your egg is buoyant but still usable crack the egg into a bowl and examine it for an off-odor or unusual appearance before deciding to use or discard it. As the egg ages air enters the egg and the air cell becomes larger and this acts as a buoyancy aid.
As the yolk in the egg starts to decompose it creates rotten egg gas and as this amount of gas increases it makes the egg float higher. When the air cell gets to a certain size the egg will float. Get crackingyour egg is still okay to eat but you should use it relatively quickly.
Alternatives to Egg Float Test. The egg sinks but stands upright at the bottom. If theyre a few weeks old but still good to eat theyll stand on one end at the bottom of the bowl.
Eggs that float in water are BAD eggs while the ones that sink are good eggs. In a fresh egg there is a very small air cell so it has little or no buoyancy. Place the egg in question in a bowl or wide glass of cold water and see if it floats.
The egg sinks and falls to its side. If the egg floats to the top of the glass of water this means the egg has gone bad and should not be used. This means the egg is older but it may be perfectly safe to use.
The older the egg gets the larger that air cell becomes. The float test can also help you determine the age of your eggs. There is a tiny air pocket inside eggs and over time more and more air passes through their porous shells and into the egg.
The rotten eggs float at the surface of the water because the matter in the eggs converts into gaseous state. So you should not throw them in the trash just yet. An egg is rotten when so much gas is present that it floats.
