The older a raw egg gets, the more air becomes trapped in an air chamber located at the wide end of the egg. As others have pointed out, when you cook an egg in boiling water, the air will expand too quickly and will burst the shell — the same way a balloon will pop with too much air.
Why do eggs explode when cooking?
Eggs have an air chamber at the bottom. Boiling them means the air inside expands and causes an explosion if you did not put in a pin prick to help the air escape the egg.
Can I eat an exploded egg?
2 Answers. Yes, it certainly is safe to eat them, it happens all the time. They won’t last quite as long in the fridge as ones which don’t crack, but as long as you eat them in a couple of days you are fine. They may look like nuclear mutants but they will taste the same.
Do old eggs crack when boiled?
Starting with boiling water offers more control over timing but this may cook the whites into a rubbery state. And it has another disadvantage: The egg is more likely to crack because the air in the egg has less time to escape as the egg heats up.
Do you have to flip eggs when frying?
Ensuring that the white is cooked and slightly puffed, and the yolk is still runny. For shallow-frying, especially in cast-iron, it is easy to achieve an over-easy, over-medium, and over-hard egg without flipping the egg over; continuously spoon the hot oil over the egg until the desired doneness has been met.
What if my eggs crack while boiling?

Can eggs explode in fridge?
Eggs typically don’t “explode” under those conditions. Eggshells are porous with an impermeable membrane lining it’s inner surface. As the egg ages, this membrane breaks down* and as the egg’s contents rot, it rots with them.
