How do I know when my hard boiled eggs are done?

Rinse immediately in cold water to stop the cooking process, or they'll become quickly over-done. For medium-boiled eggs, remove after 4 1/2 minutes. The yolks of medium-eggs should be just about solid, but moist, more like a custard than a hard-cooked egg. For hard-boiled eggs, remove after 8 minutes.

In this manner, do hard boiled eggs float when cooked?

A hard-boiled Egg will sink in plain water and will float in salt water. An egg is denser than plain water but lighter than salt water, hence so. The result may vary with raw egg when it has become old, it will float in plain water also.

How do you know that your boiled eggs are done?

As a side note, there is a way to tell a whole cooked egg from one that's raw:
  1. Spin the egg on the counter. Give it a good spin, but be gentle.
  2. Stop the egg suddenly by putting your finger on top.
  3. Immediately release the egg again.
  4. If the egg begins to rotate again, it's raw.

Is it bad if a hard boiled egg floats?

Old eggs float in fresh cold water because of a large air cell that forms as the egg cools after being laid. As the egg ages, air enters the egg and the air cell becomes larger and this acts as a buoyancy aid. Eggs that tilt so that the large end is up are older, and eggs that float are rotten.
