Do you know how to distinguish raw eggs from boiled eggs? You will definitely say, not necessarily, it depends on the situation, if the hard-boiled egg is just out of the pan, it is hot; Raw eggs it is cold. So if cold hard-boiled eggs and raw eggs are put together, can you still tell which is raw and which is hard-boiled?

You will say again, I knock on one, and if it is raw, then what is not knocked is cooked. On the other hand, if the one that is knocked open is cooked, then the one that is not knocked is raw. That's not going to work, don't crack the eggs, hehe, you're dumbfounded this time.

So how do you tell the difference between raw and hard-boiled eggs? Don't worry, I'll teach you, you'll have to prick up your ears and listen carefully.

Now, I'm going to give you a few ways to distinguish raw eggs from boiled eggs

Method 1: Place the egg on the table and twist the egg quickly with your hands. Observe its rotation after leaving your hand:

If the egg turns smoothly, it is a hard-boiled egg; On the other hand, if it does not rotate smoothly, it is a raw egg. You must be asking, why do hard-boiled eggs turn faster and raw eggs turn slower? I'll tell you why:

When the cooked egg is twisted, the white yolk is twisted together, so it turns smoothly. Conversely, when the raw egg is twisted, only the eggshell is stressed, while the egg white and yolk are hardly stressed. Newton's first law (law of inertia) shows that egg whites and egg yolks are almost immobile due to inertia.

As a result, the rotation of the eggshell is slowed down by the egg whites. That's the first method.

Method 2: After the egg has been rotating for a period of time, suddenly stop the egg for a moment, and immediately withdraw your hand. If it no longer rotates after retracting the hand, it is a cooked egg; On the contrary, if you can automatically turn a few more times after withdrawing your hand, it is a raw egg.

Again, why is that, you ask? Let me explain: because when the cooked egg is stopped, the shell, egg white, and yolk all stop, and after the hand is withdrawn, it continues to stand still.

On the contrary, when the raw egg is pressed, the shell only stops temporarily, but the egg white and yolk still rotate due to inertia. Therefore, after withdrawing the hand, it can drive the eggshell to turn a few more times. That's the second way.

Method 3: If you have a flashlight, shine a flashlight on the eggs, raw eggs can be seen through, while cooked eggs can't. Why, you ask, is that? I'm sorry, but I don't know.

This is the difference between raw and hard-boiled eggs, do you remember?
