Eggs Float Or Sink When Fresh

The freshness of an egg can be determined by placing it in a glass of water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg sinks but stands upright on its small end, it is still good but not as fresh. If the egg floats, it is not fresh and should be discarded.

This test works because of the air cell inside the egg. As an egg ages, the air cell gets larger, causing the egg to become more buoyant. A fresh egg has a small air cell, so it will sink to the bottom of the glass. As the egg ages, the air cell gets larger, and the egg will start to float.

There are a few other factors that can affect the results of the float test. The temperature of the water can affect the buoyancy of the egg. Cold water is denser than warm water, so an egg will float more easily in cold water than in warm water.

The size of the egg can also affect the results of the float test. Larger eggs have a larger air cell, so they will float more easily than smaller eggs.

Overall, the float test is a simple and reliable way to determine the freshness of an egg. If you are unsure whether an egg is fresh, it is best to err on the side of caution and discard it.

Here are some additional tips for storing eggs:

Store eggs in the refrigerator at a temperature of 40 degrees Fahrenheit or below.
Keep eggs in their carton to protect them from moisture and bacteria.
Do not wash eggs before storing them. Washing eggs can remove the protective coating on the shell, making the egg more susceptible to bacteria.
Use eggs within 45 days of purchase.
