Egg shells may seem pretty solid, but they are in fact slightly porous. 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.
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 tilting is caused by air pockets in the eggs that increase in size over time as fluid evaporates through the porous shell and oxygen and gases filter in. The older an egg gets the more gas builds up inside it. More gas = more floating!
Carefully lower your eggs into fresh cold water (do not use salted water) using a spoon:
If the egg stay at the bottom - it is fresh.
If the egg is at an angle on the bottom - it is still fresh and good to eat.
If the egg stands on its pointed end at the bottom - it is still safe to eat but best used for baking and making hard-cooked eggs.
If the egg float - they're stale and best discarded.
The final test: To make sure the egg is not spoiled, break it into a clean bowl and check to make sure it doesn't have a bad odor or appearance.
Did you Know - Eggs from your own hens (farm raised) are like homegrown vine-ripened tomatoes. Better that anything that comes from the supermarket.

i think if you boil eggs on high flame then they may float for a while and again go back to the bottom, making a cycle of movement...
we were taught that good fresh eggs should settle at the bottom of water rather then float...

I have recently learned that if you place a fresh eggs in a pot of water.... that if any of them float, they are spoiled. Regarding while they are boiling, could have to do with the same reason.

The larger the air occupied space the older the egg .If it freely floating it means it's too far gone,needs to discarded without a doubt.

If you immerse an egg in (cool) water, you can judge how fresh it is by how high it floats. Really fresh eggs won't float at all; the higher it floats, the less likely it is to be fresh.

The freshness of the eggs should apply. Why don't you compare the results from putting fresh eggs and rotten eggs in the water.
