When a person is frightened, he cries out to his soul, why do needles that are placed in a bowl and

This question involves folk beliefs and superstitions, and there is no one exact answer in science. However, we can try to explain this phenomenon from a physical and chemical point of view.

First, the needle is placed in a bowl and immersed in water, and when frightened, the needle rusts. This phenomenon may be related to a chemical reaction. Needles are made of iron, which undergoes an oxidation reaction in water to produce iron oxides (i.e. rust).

When frightened, the person's body may produce some chemicals such as adrenaline, etc., which may accelerate the oxidation reaction, which causes the needles to rust faster.

Secondly, about the soul shouting will make the needle not embroidery, which may be related to psychology. When people are frightened, their emotional and psychological state can have an impact on their bodies. For example, when people are scared, their bodies may release hormones such as adrenaline, which may speed up or slow down some of the body's chemical reactions.

Therefore, when people cry out for souls, their emotional and psychological state may change, affecting their physical responses, so that the needles no longer rust.

Overall, this phenomenon may be related to a variety of factors, such as chemical reactions, psychology, and folk beliefs. However, there is no one definitive answer in science.

Iron needles that are placed in water with a certain amount of humidity and oxygen will form rust.

This has nothing to do with the child's fright, it is a problem with the needle, the needle is iron, soaked in water and oxidized and corroded, the head and tail ends are processed, the protective coating is thin, and it is corroded first.

Why do iron needles rust when they are put in water? China's tap water disinfection adopts chlorination, which has been popularized for more than 100 years. Chlorine is soluble in water and reacts with water to form hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the entire disinfection process.

Both hydrochloric acid and hypochlorous acid have strong oxidizing properties and can accelerate the natural oxidation (rust) of iron needles. So usually iron needles will rust quickly when placed in water. Stainless steel needles do not, as they are not susceptible to oxidation.

Why are the ends of needles prone to rust? It may be because there is less anti-rust material at both ends in the process of producing needles.

Why does it rust overnight sometimes, and sometimes it doesn't? Because the rate of chemical reaction is affected by various factors such as reactant concentration, time, pressure, temperature, and phase contact area, the situation is different each time.

Abandon backward and ignorant superstitious activities.

The acidic and alkaline flow of electrons in water causes oxidation reactions.

Physical phenomenon, water can naturally "glue" the chopsticks, three chopsticks can stand stably, may be a capillary phenomenon, when the chopsticks are put on the chopsticks, the chopsticks will definitely be thick end, three leaning together, increasing the contact area between the bottom of the chopsticks and the bowl, pouring some water is to use the tension of the water, so that there is no gap between the three chopsticks.

Three chopsticks can stand in a bowl of water because the three forces are balanced, and the triangular force is the easiest to balance.

Let's make a list

Props]: Three straight chops

New red chopsticks, a bowl of clear water.

Steps]: Put the bowl flat dao on the table, three times the chopsticks thin end in the bottom answer, one hand pinch the standing bowl **.

One hand keeps picking up water from the bowl and spilling it on the top of the chopsticks, and the hand that pinches the chopsticks is loose to see if the chopsticks can stand on their own.

Scientific principle] uses the stickiness of water to make the chopsticks together, and the bottom three ends form a support surface, so that the chopsticks can stand in the bowl.

In fact, it is just some small principles in life, which have nothing to do with the gods.

Because triangles are the most stable structures.

It is also possible that there is a capillary phenomenon.

Because water has a certain adhesion, it du

Glue the four zhi chopsticks together, and the area of the dao is naturally large, forming a small fulcrum inside, and then letting go of the chopsticks will naturally "stand" straight.

Viscosity coefficient of water:

At 20, the viscosity coefficient of water is centipoise.

Definition of viscosity coefficient (viscosity):

The magnitude of viscosity is expressed in terms of the viscosity coefficient (i.e., viscosity). Chopsticks erection applies to Newton's law of viscosity (Newtonian fluid).

This is generally to wait until the baby is going to sleep at night to help him bark, call his name to let him go home for dinner, this is how my mother-in-law called the baby.

Please show it to the person who is surprised by the child.

There are many things that science cannot explain. In the face of these things, it is better to believe that there is something to believe and not to believe or not to believe or not, I grew up in the countryside when I was a child, and I have a deep feeling for these things, and now I am also a college student who is about to graduate, although I have received an education in atheism, but I will still believe in these feudal superstitions.

At our house, we use 7 postmarked stamps, pin them together with a new needle, burn them, and then the soul will come back automatically.

There is also the needle in the bowl, if the needle tip rusts in the morning, it means that the soul has returned.

Wait,.

In fact, if you don't wipe the child, it will be less, because if you shake it in the process of wiping, it won't wipe the child, and it will be less, and you don't need to ask me why I know, because, I've done experiments.

All I know is that it's magic, a lie.

Go to the hospital, believe in science, don't be superstitious.

To be honest, this time I really believe that there is such a saying, I just saw that the Internet said that vertical chopsticks are superstitious practices, but my child just experienced such a play yesterday, so godly, those three chopsticks actually stood for a long time. It's true that the child stopped crying after he finished it.

In front of this vertical chopsticks, I saw that my mother-in-law first poured a bowl of water, and then dipped the end of the meal with three chopsticks, and then turned it upside down, while saying: God year, ghost year, family and foreign age, all come to the age, while standing up the vertical chopsticks, to see which deceased relative's name can stand, and then say: You go, don't come to disturb me.

Chop down the chopsticks with a knife, then pour the water outside the door, turn the bowl over, put three chopsticks on top, and bring the bowl and chopsticks in after dark.

My child met two deceased relatives one day, and his grandmother called him that, and it was really good.

I don't think it's superstition, it's just that science can't explain it.

Maybe you've been chilling lately and you're not feeling well. There is no such thing as a sick person for no reason. And even if you find the Spirit, what if?

If he doesn't leave, you still want to be pressed on the bed, don't you? Don't invite it like a pen fairy or something. Just go to the hospital for a check-up and drink some medicine.

It's really not good, just take a little bit and it's over. Having a ghost in your heart is the most taboo. I wish you good health.

Put half of the water in the bowl, and then put the end of the food sandwich in the water and slowly hold it with your hand until it doesn't fall.
