Why does a rotten egg float but fresh egg sinks?
I'm not sure, but it might have something to do with the air pocket in the top of the egg. When an egg is fresh, the air pocket is small. As the egg ages, some of the water evaporates through the pores in the egg and so the air pocket gets bigger. Perhaps this is why a very old egg would float.Addition -The rotten egg floats, because bacteria is eating away some of the egg, which is making it lighter. Air pockets do play a role, because in this case, the bacteria is eating away the egg, which is making it lighter, and in the process is creating small air pockets, making it float.
What is the air pocket at the large end of an egg called?

How does a chick breath in its egg?
All eggs have an air pocket inside the egg the chicks beak will be slightly inside of the pocket. As the chick develops further the air pocket gets bigger. This is normally the same for reptiles and any other animal that produces eggs.
How does the density of the egg compare with the density of the plain water?
A fresh chicken egg will sink, an old egg will float. The egg has an air pocket in the blunt end that grows as the egg dries out.
What causes the dent in the egg white when you hard boil an egg?
Answer:Raw eggs actually contain an air pocket. When you boil an egg, the albumin - or the white part of the egg when boiled - retains the air's shape when it hardens during cooking.
Does an air pocket form at the end of the egg rihgt befor it hatches?
No. Air pockets have been there before the egg was even laid; primarily when the shell was deposited around the egg inside the hen. Air pockets increase in size as the chick grows.
How long does it take an egg to rot?
There is a small air pocket in the large end of an egg. When the egg is fresh, the pocket is only about 1/8th of an inch deep and about as large around as a dime. As the egg ages, it loses both moisture and carbon dioxide so that the size of the air space increases, making the egg (among other things) more buoyant. So, if you submerge a very fresh egg in water, it will lie on the bottom. An egg that is a week or so old will lie on the bottom but bob slightly. An egg that is three weeks or so old will balance on its small end. And bad egg will float.
Why would someone sink a duck egg in a jar of water?
This is a common way of checking duck and chicken eggs for freshness. If the egg stays at the bottom of the jar, it is very fresh. If if suspends towards the middle, it is not as fresh, but it is still edible. If it rises almost to the top or floats, the egg has likely gone bad. It has to do with the air pocket inside of the shell expanding as the egg ages.
What does air contain that your cells need?
An air cell is an air pocket formed at the bottom end of an egg formed by the contraption of the egg's contents through loss of moisture and cooling from its initial filled state.
If the egg floats is it a bad egg?
Yes, eggs are porous and as they age an air pocket forms in the eggs causing it to float. At the same time water vapor and gases are leaving the egg. This difference in mass will cause the egg to float.
In a group of eggshow do you know the fresh and which are old?
Hello How can I tell if an egg is bad without breaking it? Most everything has changed in the world of cooking in the past 250 years, but not the method for determining if you've got a bad egg. There is a small air pocket in the large end of the egg. When the egg is fresh, the pocket is only about 1/8th of an inch deep and as large around as a dime. As the egg ages, however, it loses both moisture and carbon dioxide - shrinking - so that the size of the air space increases. And the size of the air space determines the buoyancy of the egg. So if you submerge a very fresh egg in water, it will lie on the bottom. An egg that is a week or so old will lie on the bottom but bob slightly. An egg that is three weeks or so old will balance on its small end, with the large end reaching for the sky. And a bad egg will float. A "way to know a good egg, is to put the egg into a pan of cold water; the fresher the egg, the sooner is will fall to the bottom; if rotten, it will swim at the top." Hope you got it what you wanted. Thanks.
What would happen to an egg if you sent it into space with a weather balloon?
Depends on the porosity of the egg shell in question. If it is not porous then the air pocket would be at a higher pressure than the outside of the egg and it would fracture. If the egg is porous then the air within the air pocket would escape from the shell as the weather balloon ascended and probably won't fracture the egg.Whether the proteinaceous matter would burst the shell, I doubt it as it is solid, covalently bonded/hydrogen bonded matter- UNLESS there are tiny air bubbles within the matrixes of matter... in which case they could expand.Only one way to find out...( a prompt for meteorologists)
