How to tell if an egg is old

Eggs in Straw

I eat a lot of boiled eggs. Their easy to make and easy to grab as you head out the door. But I hate trying to peel and old egg. I saw this today and thought I would share. The original post can be found here.

If the egg sinks to the bottom of the water or only one end of it rises up slightly, you can eat it without worries. If it rises to the top of the water, you should throw it out at once, because it is unfit for consumption. The reason is, the eggshell is a porous material, which lets out moisture and lets in air. As the contents of the egg become dryer and denser, more and more air gets inside, making the egg becoming lighter over time.

How to tell whether eggs are still fit for consumption?
