Egg Breakability - Why Is It Almost Impossible?

hello, why is it nearly impossible to break an egg by its ends?

Think "arch". And it's not "nearly impossible", just a bit harder than crushing the sides.

The reason why it is nearly impossible to break an egg by its ends is due to the unique structure of an eggshell. The eggshell is composed of calcium carbonate crystals, arranged in a lattice-like structure. This structure gives the eggshell its strength and makes it difficult to break. Additionally, the egg is designed to protect the developing embryo inside, so it is naturally resistant to external forces trying to break it.

Moreover, the shape of an egg also plays a role in its breakability. The curved shape of an egg distributes the force applied evenly, making it difficult to break by its ends. This is known as the principle of arches, where the curved shape helps to distribute stress and prevent breakage.

Furthermore, the eggshell is also coated with a thin layer of protein called the cuticle. The cuticle acts as a protective barrier, making the eggshell even stronger and more resistant to breakage.

In summary, the combination of the unique structure of the eggshell, its curved shape, and the protective cuticle makes it almost impossible to break an egg by its ends. So the next time you try to break an egg by its ends, you'll know why it's such a difficult task!
