The method of separating raw eggs from boiled eggs

How do you use physical methods to determine whether an egg is raw or cooked?

a) Place the eggs on the table and twist the eggs quickly with your hands. Observe the rotation after leaving the hand: if the egg rotates smoothly, it is a cooked egg; On the other hand, if it does not rotate smoothly, it is a raw egg.

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.

2) After the egg has been rotated for a period of time, suddenly press the egg for an instant, 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.

Because when the cooked egg is stopped, the eggshell, egg white, and yolk all stop, and after the hand is withdrawn, it continues to stand still.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.

Best: First, the boiled egg will float on the water when it is boiled, second, stand it up and turn it, what can be turned is cooked, and what can't be turned is raw Third, shake it with your hand, when the raw egg is shaken, there will be a certain shock, when the cooked egg is shaken, there is no feeling, and the fourth is to open it directly - it is not easy to type on the mobile phone!! Yours is my biggest motivation.

There are many ways to do this, but I'm guessing you'll be able to tell the difference without destroying the eggs! Wouldn't you know if you could smash it? It's very simple to distinguish, shake it, cooked eggs will not have a sense of shaking and shaking, and raw eggs will have a shaking feeling, because it is liquid inside, of course there will be that feeling!

Cook two eggs at a time in a lifetime, turn them at the same time, and suddenly tap them to stop. What stops immediately is cooked, and what is left is raw.

Put raw and hard-boiled eggs in a cup, and then add salt little by little, and the hard-boiled eggs float first.

Pick up the eggs and shake a few of them, and if you hear the sound of water inside, it's raw.

If there is no movement, it is cooked

Put it next to your ear and shake it, and what makes no sound is a hard-boiled egg.

Turn on the table, and the hard-boiled eggs turn evenly and quickly.

The raw eggs are slow, and they are still dangling

Open the eggshell at a glance!

Put it on the table and turn it, and the fast one is cooked!

Just open it, and let me teach you.

How do you tell the difference between boiled and raw eggs? I saw this subtitle on a book and thought it was funny. After reading it, I also want to share it.

In fact, the method is very simple, the rotation of cooked eggs and raw eggs is different, through this, we can easily distinguish between them.

Put the two eggs to be separated on a flat plate and rotate them, if it is a cooked egg, then it will spin quickly and it will take a long time; On the contrary, if it is a raw egg, it is difficult to get it to spin.

If it's a hard-boiled egg that has been boiled for a long time, it spins quite fast, and all you see is a white shadow, which can even stand up its sharpest end.

Why is that? This is because cooked eggs are solid, and the yolk and egg whites that originally appeared liquid have solidified, while raw eggs are not. When spinning, due to inertia, there is no way for the raw egg to remain stable, and the yolk and egg whites inside act like brakes.

Another point is that when the rotation stops, raw eggs are not the same as cooked eggs. If it's a hard-boiled egg, pinch it with your hand during the spinning process, and it will stop immediately, but if it's a raw egg, even if you stop while pinching, it will continue to spin for a while as soon as you let go. In the final analysis, it is the effect of inertia, when pinching raw eggs, although the eggshell makes you pinch, but the egg whites and yolks inside are still rotating, and the chicken cooked eggs are different, it is already a whole inside and out, so it will stop immediately.

There is another way to separate cooked eggs from raw eggs. Find two rubber bands, tie them along the meridian of raw and cooked eggs, and hang them on the same thread.

Turn these two lines the same number of turns, and then let go at the same time, and you will notice the difference, due to the effect of inertia, the cooked egg will continue to rotate in turn after a certain number of turns, and repeat several times.

Raw eggs are different, because the yolk and egg whites inside are liquid, and due to inertia, they will stop after two or three turns at most, much earlier than cooked eggs.

I remember when I was listening to a book before, I once heard a passage that there was a competition in the martial arts competition, which was to identify hard-boiled eggs.

The method is: in a plate of raw eggs, there is a cooked egg, you can only observe with the naked eye, within the specified time, accurately identify the cooked egg, you are the winner.

This difficulty coefficient is higher, the above is the dynamic contrast, and here is the static**.

Only those who are superior in martial arts and the masters of the masters can distinguish them.

When I listened to the book, it was said that there were two masters who could distinguish it, as if it was by observing eggshells.

1. Put the egg on a horizontal smooth table, do not be horizontal and smooth, then put the egg on the table, rotate the egg on the table, and then use a finger to suddenly fix the egg for a second or two and then let go, see if the egg continues to rotate, if it continues, it is raw, otherwise it is cooked. 2. The appearance of raw eggs is relatively rough, and you can see small protrusions one by one, and the appearance of cooked eggs is relatively smooth, and the feel is smoother than that of raw eggs. If you are interested, you can compare the hard-boiled eggs, and the comparison will have an effect.

3. If it is a freshly cooked egg, it can smell a relatively strong aroma of cooked eggs. Raw eggs, on the other hand, have a slight lime taste. 4. Hold the egg with two fingers and gently shake it next to your ear, if you are raw you can feel the shaking sensation of the liquid in the egg, and the cooked egg is very heavy.

5. Put the eggs under the light, and see that the inside of the eggs is clear and transparent, which is raw eggs, otherwise it is a cooked egg. This method is less reliable.

1. Rotation method. Place the egg that needs to be identified on a level smooth table, the table should not be flat, then place the egg on the table, rotate the egg on the table, and then use one finger to suddenly hold down the egg to prevent it from spinning, see if the egg continues to rotate, if the egg continues to rotate, it is raw, and vice versa.

2. Look at the appearance and feel. The appearance of raw eggs is relatively rough, and if you look closely, you can see the small protrusions of each grain, and the appearance of cooked eggs is relatively smooth, and the feel is smoother than that of raw eggs.

3. Smell the smell. If it is a freshly boiled egg, you can smell a relatively strong aroma of cooked eggs. Raw eggs, on the other hand, have a slight lime taste.

Update 1:Only 9 of the 10 eggs are man-made.

Update 2:I don't want everyone to help

Most people who eat raw eggs --- will add hot milk to drink, and dip food when they hit Bianlu, and liquid Li.

There are many types ---of boiled eggs, such as scrambled, steamed, boiled, fried, solid, and white, and the yolk will change to loose due to heat (when it is overcooked, it will be gray and yellow) and it will be yellow when fried.

If you don't open the egg, you can know that you only touch the liquid egg is raw and cooked, as long as the egg is turned, and the turn is multiple circles on behalf of the system, because the noodles are liquid and not solid, and the cooking will stop quickly.

Eating raw eggs is highly nutritious, and it is easy to laugh at the human body to absorb, but it is safe to eat, and it is necessary to wash the eggshell first, because it is always tied to both pet pet and pet, and it will be safe to eat a d, and it is relatively small for Hong Kong people to eat raw food, most of them are fried first, and the yellow is unripe, and a series is hot milk to beat an egg.

Answer: The artificial system uses a d plastic and a d animal tissue day out of Li, it is difficult to see that the hand can be touched and smooth, and it is light to be fake, because it uses plastic to get out of Li, and it is more likely that the egg is red than the normal egg, but it is strange that the whole fake is more troublesome than the chicken itself, I don't know why D people want to make a whole holiday, I only know that eating raw eggs is a very stupid thing, and now Salmonella can kill people, and eggs are very likely to have this germ. In addition, raw eggs are difficult to digest.

So still don't try. There are many safe ways to absorb protein, not raw eggs. And rocky's movie was made more than 20 years ago. ,
