Should eggs float or sink when boiling?
To perform the float test, place the egg in a large bowl of water. If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy.
How do you tell if eggs are done boiling?
