Little Eggs Know More

Eggs are the food of our daily life and can be seen everyday, but as long as we observe and think hard, there is a lot of knowledge in the eggs.
Science in the Rotation of Eggs.
One day, I naughtily put my mother’s boiled eggs into the raw eggs. After a long time, I told my mother that it was okay for her to laugh and say that she could distinguish them. Mom picked up an egg in the box, put it on the table and rotated it for a while. Mom took an egg and said, “That’s it. It’s the cooked egg.” I felt that there was no heat in the eggs. Looking at it again, I could not see the difference between raw eggs. I wondered. I asked my mother why. Mother told me that the speed of the rotation of eggs can tell whether the eggs are raw or cooked. Because the eggshell is liquid, it is not easy to rotate, the rotation speed is slow, and the rotation time is shorter. The white and yolk in the cooked eggs become solid, and the eggs are easy to rotate, so the rotation speed is faster and the time is longer. I took out a raw egg and turned two eggs on the table, as it was. Turning around, I found another problem in the rotation of eggs:
In the process of rotation, if you hold the cooked egg gently with your finger and wait for the finger to leave after the egg stops rotating, the egg will remain motionless, but the raw egg will continue to rotate after the finger leaves. This discovery surprised my mother, so my mother and I continued to experiment, constantly turning a raw egg, a cooked egg, press, stop, then turn, press, stop, found that indeed there is such a phenomenon! What is the reason?
My mother and I began to use the knowledge reserve to think and communicate. After consulting the data, we finally understand that the liquid in the eggshell of a raw egg rotates when the egg rotates. When the egg stops under the action of external force, the liquid in its body still rotates under the action of inertia. Therefore, after the finger leaves, the egg will continue to rotate under the action of the liquid in the egg, while the yolk in the cooked egg becomes solid, which is connected with the eggshell. When the eggshell stops moving, the yolk stops moving, so the finger leaves and it does not rotate. The original eggs have such a profound knowledge of physics, what knowledge is there in the eggs? Didn’t expect to find a secret when knocking eggs.
The air chamber in an egg.
I want to make a doll. I need an eggshell to make a mould. Mother let me prepare for myself. So I took an egg and looked at its big head and small head. I thought about it. I pointed it at the kitchen table and knocked it gently. The egg cracked a small hole. I carefully uncovered a small piece of eggshell. A thin film protected the egg white. I gently smashed it and the egg white slowly flowed out. I took another egg and knocked it open from my big head, but I found a small space between the egg shell and the egg white. What’s the matter? Is there a problem with this egg? I opened another one, or so, and then I opened three eggs in one breath, all of which are the same. Originally, the egg white did not fill the space inside the egg. There was still such a little space inside. What’s the use of this space? I gathered information before I knew:
Normal eggs are big and small. The big head has a small chamber full of air, called an air chamber. When the chicken is coming out, its head is in the big head. Finally, it puts its mouth into the air chamber and begins to breathe directly into the air chamber. Therefore, in the embryonic period, chickens must have air chambers in order to grow normally. Oh, it was a room for chicken development. It seems that oviparous animals, like fetal animals, need normal breathing during embryonic development. Eggs, four or two can pull a kilo.
Eggs, four or two, can also pull a kilo.
We all know, and we may have done experiments like this. If you hold an egg in one hand and press it hard, no matter you are an ordinary person or a Hercules, it is impossible to crush the egg. There are also some scientific reasons. This is a physical phenomenon, it is related to the shape of the egg: the shape of the egg is elliptical, its arched shell can evenly distribute the pressure to each part of the shell, when pinched with the whole palm, because the force on the hand disperses to the surface of the whole egg, the pressure is very small, so it can not crush. But if two fingers pinch the eggs at the same time, because the contact surface is small and the pressure is concentrated at one point, the eggs will naturally break easily. According to this principle, scientists invented tunnels, arch bridges, safety hats and so on. It greatly facilitates people’s life.
You see, there is a lot of scientific knowledge in little eggs. In fact, in our life, there are many natural phenomena which contain mysterious and infinite scientific knowledge. It needs us to discover, think and explore.
