What Does It Mean When An Egg Floats

This means the egg is old but it may be perfectly safe to use.

Floating can be a sign an egg isn t as fresh as you might want it to be but it takes closer inspection to determine whether the egg is spoiled. But if it floats to the. It all depends on time and the eggshell. An older egg will either stand on its end or float.

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. Some ambient air enters the shell as the water vapor and decomposition gasses leave but overall the mass of the egg is reduced. So the older the egg the more air can penetrate its shell causing it to float. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant.

Because a rotten egg can cause food poisoning it s important to find out about freshness and quality. The shells of eggs are not impermeable. If an egg sinks to the bottom of a bowl of water and lies sideways it is very fresh. It may also be that the egg is older but not rotten.

The science behind this is based on the fact that eggshells are semipermeable which means air can get through. This means the egg is older but it may be perfectly safe to use. As a general rule if an egg floats at the top of a container of plain water it is a bad egg. The reason why an egg floats is because as it decomposes water vapor and gases are released through the porous shell.

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. If the egg sinks or stays at the bottom it is still fresh. This does not necessarily mean that it is spoiled but it is definitely not at all fresh.
