Experiment with eggshells requires that you wrap the eggs in your palm and touch them with your fingertips to see if they are broken. why

1, although the shell of an egg is very fragile, the unique shape of the egg makes it have a solid shell, in which the top and bottom of the egg are the strongest, which is why the egg will not break when you apply pressure on both ends of the egg.

When you hold the egg horizontally in the palm of your hand and squeeze it, you distribute the pressure evenly on the whole egg. The arc of the eggshell can distribute the pressure evenly, instead of concentrating all the pressure in a certain area.

When only one side of an egg is under pressure, it will break because the pressure is concentrated on one side.

In daily life, when people beat eggs, they are used to knocking the horizontal side of the eggs against the edge of the bowl, and the eggs will be broken. This also explains that when a hen sits on an egg, the egg will not break, but a chick can penetrate the eggshell: the weight of the hen is evenly distributed on the egg, while the chick acts on a certain position of the egg with uneven force.
