Here are a few tips to distinguish old and new eggs:

- The first is to use 3 ounces of salt, dissolved in a water bowl. Put the eggs into the bowl. 1-2 day old eggs will sink to the bottom of the bowl, 3 day eggs will a bit float, 5 day eggs float above the water surface.

- There is one more way. Put eggs into water. If the eggs small end down, the eggs are new. However, this way is difficult to use when selecting eggs at the market. So, another way is that you raise eggs out of sunlight or a lamp, which has many gaps on end is took so long. Eggs with very small gap are new.

- Also, if you shake the eggs in your ear without noise is a new egg. If you flap gently two eggs together, new eggs have strong bass sound, old ones sounds like knocking tile.
