Why is a floating egg bad?
As the egg ages, air enters the egg and the air cell becomes larger and this acts as a buoyancy aid. Generally, fresh eggs will lie on the bottom of the bowl of water. Eggs that tilt so that the large end is up are older, and eggs that float are rotten. The older an egg gets the more gas builds up inside it.
What does it mean if an egg floats instead of sinks?
