This does not necessarily mean that it is spoiled but it is definitely not at all fresh.

The egg will still be good enough to consume however if the egg fully floats in the water and does not touch the bottom of the bowl at all it should be discarded as it will most likely be bad. So as it ages more of this moisture will leave which in turn provides more space for air to enter the egg. Some ambient air enters the shell as the water vapor and decomposition gasses leave but overall the mass of the egg is reduced. The reason why an egg floats is because as it decomposes water vapor and gases are released through the porous shell.

This means that the fresher an egg the more likely it is to sink as there is not enough air on the egg to keep it afloat. 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. When an egg floats it s because a small air pocket inside the shell has had enough time to expand sufficiently to make the egg buoyant. This means the egg is older but it may be perfectly safe to use.

Because a rotten egg can cause food poisoning it s important to find out about freshness and quality. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. As the egg begins to age both moisture and gases within the egg will seep through the egg s porous shell. The shells of eggs are not impermeable.

As a general rule if an egg floats at the top of a container of plain water it is a bad egg. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This is what causes the yolk and whites to shrink which in turn makes the air cell larger.

Look at the color of the egg white. The second method to test the eggs freshness is by breaking the egg. It may also be that the egg is older but not rotten. It all depends on time and the eggshell.

Video of the day. This means the egg is old but it may be perfectly safe to use. If the yolk moves around easily this means the chalazae the thicker strands of egg white that hold the yolk in place have weakened and the egg is aging.
