How did you see through the swindler's scam? Tell me about your experience?

Clear water explodes for no reason, white paper suddenly shows blood stains, cotton thread keeps burning, bare hands reach into the tumbling oil pan, cotton thread keeps burning, and white paper suddenly shows bloody handprints ... these are all tricks used by those witches to deceive the public. It is through these seemingly counterintuitive phenomena that they convince some people who are ill and go to the hospital indiscriminately that they have some mysterious power to avoid disasters for people. Innocent people were not only cheated of money, but even put their lives on the line. What tricks are hidden in these quacks? We will answer them for you one by one.

Deception 1:

Fried ghost

A pot of steaming oil is about to boil. But some masters who claim to have magic can actually put their hands into the boiling oil pan. This usually makes others stunned. If oil spills on your hands when cooking, most people can't stand it. Are they really not afraid of being burned when burning oil?

Deception. Deception

Actually, this is not a real pot of oil. After a pot of oil is boiled, the temperature will reach two or three hundred degrees Celsius, which will definitely cause harm to people. There must be something else in this pot of oil, usually vinegar, because the density of vinegar will be relatively high, so it will sink under the oil when put into the pot. We look like a can of oil from above, but we can't see vinegar. Vinegar will boil first when heated because of its low boiling point. Then the bubbles will swell to the oil surface, which looks like the oil is boiling, but in fact, the temperature at this time is only about 60 degrees Celsius, which will not cause harm to people. If you want to further reduce the temperature, you can also add chemicals such as calcium carbonate or borax to the pot, so that gas will also be generated due to chemical reaction, and bubbles will also rise above the oil level, making the oil look like boiling. At this time, the temperature will be lower, and it will not cause harm to people. You can rest assured that you can cast spells boldly.

Deception 2:

White paper and blood print

Originally it was a piece of snow-white paper. When the "master" slapped it hard, I saw a bloody handprint on the paper. At this time, "masters" will often tell you that foxes, monsters and ghosts at home have been surrendered by him. "Master" then put the paper with blood fingerprints into the basin, and the blood fingerprints slowly disappeared. The "master" explained that the ghost was finally driven away.

Deception. Deception

This trick is mainly a chemical reagent phenolphthalein at work. Phenolphthalein will turn red in case of alkali and fade naturally in case of acid. In fact, the "Master" took advantage of this simple chemical reaction. First, spray phenolphthalein on a piece of white paper and dry it. It still looks like a good blank sheet of paper. Then when doing it, dip your hand in some alkaline water and pat it up, so that there will be a red handprint after the reaction. When you put it in a basin, you can exchange some dilute hydrochloric acid and white vinegar in water, so that when the paper is put in, it will naturally fade when it meets acid, and the blood fingerprints will be gone.

Deception 3:

Huoshao cotton thread

A copper coin was hung by an ordinary cotton thread, and the "master" lit the cotton thread. Strangely, the cotton thread was burning, but it kept burning. This is also the trick that experts usually use, claiming that the cotton thread has been burning because the magic of ghosts is too clever.

Deception. Deception

The cotton thread used by the master was actually tampered with by him. The cotton thread may have been soaked in brine, which is used to order tofu and contains substances such as potassium chloride and magnesium chloride. The copper coins tied with such a wire seem to be on fire, but in fact they only burn on the surface of the wire, and the inside of this wire is protected by potassium chloride and magnesium chloride, so it does not burn.

Deception 4:

Clear water explosion

The "master" held a needle in his hand and revolved around a basin of water, and then the needle really floated on the water. At this time, the "master" will often say that this is because the water ghost lifted the needle. Prove that there are water ghosts, and the "master" naturally wants to take money to eliminate disasters, claiming that water ghosts can be eliminated. I saw the fingers of the "master" turning slowly and leisurely in the basin, and something suddenly appeared in the basin. Are there really ghosts in the water? At this time, the washbasin actually exploded, emitting a thick smoke.

Deception. Deception

In fact, the needle can float on the water, not because of the role of gods or ghosts, but because the water has a certain surface tension. When we put a needle or coin that is usually thought to sink to the bottom of the water gently, we will see that the water surface will sink, and the sunken water surface will generate an upward force to hold the needle or coin so that it will not sink to the bottom of the water. This is actually a very simple physical phenomenon, the so-called "master". And how can water explode? Actually, I secretly threw a piece of sodium into the basin. Sodium metal is very active. When it meets water, it will burn quickly and have a violent chemical reaction. Even this kind of explosion will happen. The first time you throw a small piece, the second time you throw a big piece. Once it explodes, you say the ghost has been removed.

Deception 5: Finger spontaneous combustion

"I'm going to exorcise ghosts." Masters usually get their hands wet first, and then they are covered with flour. I saw the master fanning left and right, his fingers dangling on the table, and his mouth still murmured, "Shoot you to death" and "Catch you". Then my finger flashed, and suddenly there was a fire on my finger. It is said that this will also catch ghosts.

Deception. Deception

How can a finger catch fire? It's actually quite simple. Generally, the master will sprinkle three kinds of powder on the table in advance, the first is camphor, the second is phosphorus, and the third is sulfur. Then he touched the flour on his fingers in advance, so he shook it back and forth on the table, and then all three kinds of flour were touched on his hands. Then the whole room was filled with smoke. He shouted and shook hard in the air. Camphor is volatile, and sulfur and phosphorus burn easily. Because he had a layer of powder on his hand in advance, the fire was immediately put out by him, so it was not a problem at all.

Deception 6: the snake demon appears

An ordinary piece of yellow paper can make the snake demon appear? This is a ridiculous thing, but it has deceived many people. Masters usually say that you are haunted by ghosts, such as snakes and demons. Only he can make the snake demon appear, but this naturally requires the role of money. Once he got the money, the master took out a piece of yellow paper and put it on the incense burner to start burning. The yellow paper was first burned with a hole. With the continuous expansion of the black hole, the yellow paper really looks like a snake as the master said, which is what he called a snake demon.

Deception. Deception

When we saw the paper meet the incense burner, the shape of a snake appeared magically. In fact, the "master" painted on the paper in advance with a chemical substance, which is usually potassium nitrate, because potassium nitrate is a component of gunpowder, a strong oxidant and combustion improver in chemistry, and is relatively soluble in water. The "master" may have drawn the shape of a snake on paper with potassium nitrate solution. After drying, potassium nitrate particles are attached to the paper, so that once the paper encounters fire, the part attached with potassium nitrate is particularly easy to burn.
