Here is a wonderful test to find if an egg is fresh or rotten. You need a large bowl of water and 3 eggs - one fresh, the other 15 days old and the third more than a month old. Place the fresh egg in the bowl and it will sink to the bottom. This is also a test for the FRESHNESS of the egg. Next, take the old rotten egg and place it in the bowl and it will float up. Finally if you place a 2-week old egg in the bowl it will only partially float. 
To know if an egg is fresh or rotten float it in water. The fresh egg being heavier will sink. The rotten egg will have a lot of accumulated gases which will make it lighter and so it will float.
