Do hard boiled eggs float when they are done?
No. Old eggs tend to float, whether raw or boiled, as they have lost moisture and their density has decreased. Fresh eggs sink in water, whether raw or hard boiled.

Why do my hard boiled eggs have a flat bottom?
This is because as the egg gets older and its contents begin to contract, the yolk begins to droop, and the air cell at the bottom of the egg expands, creating yolks that aren’t centered and whites that have flat bottoms (similar to what happens to us as we age!).

Why are my boiled eggs still runny?
If the protein level drops, it might make it harder to set and stay runny. Egg white proteins go through a phase change (become hard) at a lower temperature than the Yolk by a few degrees, that’s how you can have soft-boiled eggs.
What happens when a boiled egg floats?
If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air. If the air pocket becomes large enough, the egg may float. An egg can sink and still be bad, while an egg that floats may still be fine to eat (3).
What do overcooked eggs look like?
If you have noticed, overcooked eggs have a green coating on their yolk, which is a signal that you should not eat them. Why it happens? The hydrogen sulphide originates in the whites of the eggs and the protein in the white contains sulphur that combines with the hydrogen to form a deadly gas.
