Good Eggs Float Or Sink

When you buy a dozen eggs, you want to be sure that you're getting fresh, high-quality eggs. One way to test the freshness of an egg is to see if it floats or sinks in water. Fresh eggs will typically sink to the bottom of the glass, while older eggs will float.

This is because as an egg ages, the air cell inside the egg grows larger. This is due to the loss of moisture through the shell. The larger air cell makes the egg more buoyant, which is why it will float in water.

There are a few exceptions to this rule. For example, some eggs may float even if they are fresh. This is usually due to a condition called "floating air cell." Floating air cell is caused by a small amount of carbon dioxide gas that is trapped inside the egg. This gas can make the egg more buoyant, even if it is fresh.

Another exception is eggs that have been hard-boiled. Hard-boiled eggs will always float in water, regardless of their freshness. This is because the cooking process causes the proteins in the egg to coagulate, which makes the egg more dense.

If you're not sure whether an egg is fresh, the best way to test it is to crack it open and examine it. A fresh egg will have a firm, round yolk and a clear, thick white. If the yolk is flat or runny, or if the white is thin and watery, the egg is not fresh.

Here is a step-by-step guide on how to test the freshness of an egg using the float test:

Fill a glass with cold water.
Gently place the egg in the water.
Observe whether the egg sinks to the bottom, floats in the middle, or floats at the top.

If the egg sinks to the bottom, it is fresh.

If the egg floats in the middle, it is not as fresh, but it is still edible.

If the egg floats at the top, it is not fresh and should not be eaten.

The float test is a quick and easy way to test the freshness of an egg. By following these steps, you can be sure that you're getting fresh, high-quality eggs.
