What Does It Mean If An Egg Floats In Water

An egg is standing up or even partly floating is an indication that it is not very fresh.

This means the egg is older but it may be perfectly safe to use. If the egg sinks and stands up on one end it s not fresh but it s still safe to eat. A bad egg will also feel extremely light in weight and give off a pungent smell. It all depends on time and the eggshell.

Click to see full answer. 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. The science behind this is based on the fact that eggshells are semipermeable which means air can get through. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant.

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. When a bird lays an egg at its freshest point the egg will have in most cases a very small air pocket or none at all. Crack the egg into a bowl and examine it for an off odor or unusable appearance before deciding to use or discard it. When an egg ages the air pocket between the shell and the membrane around the contents gets bigger giving the egg the lift.

An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. Density is the key reason and is a simple scientific explanation for why eggs sink in fresh water but float in salted water. Of course if any eggs float to the top they shouldn t be eaten. So the older the egg the more air can penetrate its shell causing it to float.

One easy way to tell if an egg is bad is to carefully place it in a large bowl of water. 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. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. The second method to test the eggs freshness is by breaking the egg.

If the egg floats there s a good chance it s bad. 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. However there are a few other possible explanations for what it means when eggs are floating while boiling in hot water. An egg that floats in boiling water can be an indication that it s not fresh.

If the egg sinks to the bottom on its side it s fresh. 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. If you cook it it most likely is still safe to eat but it might have lost some of its flavor.
