Is An Egg Good If It Floats Or Sinks?
The float test is a simple method to determine the freshness of an egg. When an egg is placed in a bowl of water, its density will determine whether it sinks or floats. Fresh eggs will sink to the bottom of the bowl, while older eggs will float.
The reason for this is that as an egg ages, the air cell inside the egg will gradually increase in size. This is due to the evaporation of water from the egg, which causes the air cell to expand. The larger the air cell, the more buoyant the egg will be, and the more likely it is to float.
So, if you have an egg that floats in water, it is likely an older egg. This does not necessarily mean that the egg is bad, but it may not be as fresh as an egg that sinks to the bottom of the bowl.
How to Perform the Float Test
To perform the float test, simply fill a bowl with cold water and gently place the egg in the 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 end, it is slightly older but still good to eat. If the egg floats, it is best to discard it.
Other Factors That Can Affect Egg Floatation
It is important to note that the float test is not a perfect indicator of egg freshness. There are other factors that can affect the floatation of an egg, such as the temperature of the water and the size of the egg.
For example, cold water will make an egg float more than warm water. This is because cold water is denser than warm water, so the egg will be less buoyant in cold water.
Additionally, larger eggs will float more than smaller eggs. This is because larger eggs have a larger air cell, which makes them more buoyant.
How to Store Eggs
To keep eggs fresh for as long as possible, it is important to store them properly. Eggs should be stored in the refrigerator at a temperature of 40 degrees Fahrenheit or below. They should also be stored in their original carton to protect them from moisture and bacteria.
Eggs can be stored in the refrigerator for up to four weeks. However, it is best to use them within two weeks for optimal freshness.
