How can I test for freshness of eggs without cracking them open?
There is a quick and easy was for checking the freshness of your eggs without using them. Simply place an egg into a bowl of water. A fresh egg will generally lie at the bottom of the bowl. As an egg ages the air cell inside the egg increases which will cause the eggs to float to the top. This test is should be used as a guide only as there are other factors that could cause a fresh egg to float such as a light shell.
