Egg Sink Or Float Test

The egg sink or float test is a simple experiment that can be used to determine the freshness of an egg. The test is based on the fact that as an egg ages, the air cell inside the egg becomes larger. This causes the egg to become less dense and more likely to float. A fresh egg will sink to the bottom of a glass of water, while an older egg will float to the top.

To perform the egg sink or float test, you will need the following materials:

A glass of water
An egg

Instructions:

Carefully place the egg in the glass of water.
Observe what happens to the egg.

Results:

If the egg sinks to the bottom of the glass, it is fresh.
If the egg floats to the top of the glass, it is old.

The egg sink or float test is a quick and easy way to determine the freshness of an egg. This test can be used to help you avoid eating spoiled eggs.

Other Factors That Can Affect Egg Freshness

In addition to the air cell, there are a number of other factors that can affect the freshness of an egg, including:

Storage temperature:
Eggs should be stored in the refrigerator at a temperature of 40 degrees Fahrenheit or below.
Storage time:
Eggs can be stored in the refrigerator for up to 45 days.
Egg size:
Larger eggs have a larger air cell and are therefore more likely to float than smaller eggs.
Egg quality:
The quality of an egg can also affect its freshness. Eggs that are cracked or have thin shells are more likely to spoil quickly.

If you are unsure about the freshness of an egg, it is best to err on the side of caution and discard it.
