Specific steps:

1, prepare materials.

2. Put borax into the bottom of the cup, pour a small amount of warm water into the beaker, and fully stir to make borax dissolve as much as possible.

Take some glue and put it in a plastic bowl. You can use the bottle cap of glue as a measuring container. Then, pour the same amount of water (or a bottle cap with glue). Remember, the ratio is 1: 1, neither too much nor too little water, stir.

Primary school students were admitted to the hospital after eating borax poisoning, and were allowed to play with three crystal mud (trainee reporter Li Shuaiwen). Colorful crystal mud has become a toy for many children. I believe many parents have seen their children play with crystal mud or buy DIY (meaning "DIY") handmade materials for their children. However, you must pay attention! According to Professor Yi Zhu from College of Food Science and Nutritional Engineering of China Agricultural University, crystal mud contains borax, which can cause acute poisoning. Long-term exposure to borax toxin will accumulate in the body.

A few days ago, a 12-year-old pupil in Suqian, Jiangsu Province was poisoned by eating borax, which was used to make crystal mud. An 8-year-old girl and a 1 year-old boy in Guangzhou also suffered from severe vomiting and other discomfort symptoms due to misuse of cups containing crystal mud. In this regard, the reporter visited a number of shops around two primary schools in Zhengzhou and found that not only tools such as borax of DIY crystal mud are popular, but many finished crystal mud are "three noes" products.

Investigation: there is borax in the crystal mud, and the toxin will accumulate in the body after long-term contact.

Crystal mud, also called "slime mud", is similar to jelly in texture, cool and soft, but a little sticky. This kind of crystal mud can not only buy ready-made finished products, but also buy DIY materials for hand-making. The production method is also very simple. There are many tutorials online and in some mobile video apps. The simplest method is to use borax water and glue, add some pigments, and stir well to make crystal mud.

According to a netizen who has made crystal mud, if there is no borax water, you can also make crystal mud with borax. After borax is dissolved in warm water, it is poured into a container filled with clay, and glue, pigment and sequins are added to make colorful crystal mud.

From video tutorials to netizens' explanations, making crystal mud is inseparable from borax and borax water. So, what is borax?

It is understood that borax is a chemical product, usually a white powder containing colorless crystals, which is easily soluble in water. It has the function of disinfection and bacteriostasis in medicine, and is also widely used in pesticide, cosmetics and other fields. The most important thing is that borax is highly toxic, and it is forbidden to be used as a food additive in many countries in the world. China's "Food Hygiene Law" and "Hygienic Management Measures for Food Additives" also explicitly prohibit the use of borax as a food additive.

In this regard, Professor Yi Zhu from College of Food Science and Nutritional Engineering of China Agricultural University said in an interview with Dahe Daily that the scientific name of borax is sodium tetraborate, and the toxic dose for adults is 1g to 3g, and the lethal dose for adults is 15g. If children eat borax by mistake, the mortality rate is higher. Borax will react with gastric acid to produce boric acid after ingestion, which may lead to acute poisoning, usually manifested as vomiting, diarrhea, erythema of skin and so on. Borax enters the human body and is absorbed quickly and excreted slowly. Borax is mostly excreted through urine, and a small amount can also be excreted through sweat and milk. Usually, 50% of the intake can be excreted from the urine within one day, and it takes about a week or more to completely excrete.

Professor Yi Zhu also said that borax is more harmful to human body, and it accumulates in human body. Long-term exposure and intake will slowly accumulate in the body, interfere with the action of digestive tract enzymes, cause loss of appetite and indigestion, inhibit the absorption of various nutrients, promote fat decomposition, and lead to weight loss.

Visit: Under the banner of DIY, "three noes" borax sells well at the gate of primary school.

On the morning of March 19, the reporter visited a number of shops around two primary schools in Zhengzhou, and found that almost every shop not only sold finished crystal mud, but also sold borax, borax water, glue and other materials for making crystal mud. In the stationery store around a primary school near the intersection of Fengchan Road and Yaozhai Road in Zhengzhou City, you can see all kinds of crystal mud on the shelves as soon as you enter the door. These jelly-like crystal mud are packed in large and small plastic boxes, and there are many DIY tools for making crystal mud next to them. When the reporter asked the shopkeeper "what materials are needed to make crystal mud", the shopkeeper found a bottle of glue and some sequins on the shelf, as well as a small box containing white powder. There is no trademark on the small box, and there is no sign of any words. When the reporter asked "What is the white powder in the small box", the stationer replied: "There is borax in it, which is an essential material for making crystal mud. A box of one yuan. "

In another stationery store, there are crystal mud and borax of DIY crystal mud on sale at the door of the store. Borax sold in this shop is packed in small bags, each bag weighs about 100g, and there is no trademark or logo on the outer packaging. According to the shopkeeper, the main raw materials for making crystal mud are borax and liquid glue, plus some pigments, glitters and trinkets. One or twenty dollars can make crystal mud with beautiful colors, which many children like, and many parents help their children to buy and sell very well. When the reporter said that he only wanted to buy a bag of borax separately, the shopkeeper said that he could sell each bag of 4 yuan.

Subsequently, in three shops around a primary school at the intersection of Liu Zheng Street and Hongqi Road, the reporter saw not only DIY crystal mud borax for sale, but also large bottles and small bottles of borax water for sale. The outer packaging of borax water is good, with the name, preparation method and warning of "Do not eat", but without the manufacturer, address, materials and other contents. Its price is divided into 5 yuan and 10 yuan according to the size of the bottle. Similarly, three shopkeepers also told reporters that DIY crystal mud materials in their stores sell well. According to one of the shopkeepers, all the DIY materials of crystal mud in his shop were bought online. Students like it, things sell well, and he keeps up with the needs of students. As for how to do it, he is not clear. "How to do it, the child will, if you buy it back, the child will do it."

Through the Internet, the reporter searched for two key words "crystal mud and borax" on a shopping website, and immediately popped up 100 page about the sale of crystal mud made of borax or borax water. The highest monthly sales volume reached 1. 1 10,000 copies. In addition, during the interview, the reporter also found that a large number of finished crystal mud was only packaged in a simple plastic box, and there was no information such as manufacturer, address and material. Even the store that sells them can't tell where these crystal purees are produced, and many of them are added with very strong spices. As long as you open the lid, you can smell the pungent smell. I wonder if such "three noes" products and the smell of * * * will affect children's health.

Supervision: Relevant departments will be involved in the investigation.

"I like making crystal mud very much. There is a big box at home. I bought it myself, and my classmates sent it. " During the visit, a third-grade pupil told the reporter that her good friend made some crystal mud at the earliest. She thought it was fun, so she bought some materials to do with her. The more she does, the more she likes it. She often buys materials at the school gate and goes home to do it.

"At school, teachers don't let me play, many students secretly play, and female students play a lot. I also bought a small box. " Another fourth-grade pupil said that there were many students playing with crystal mud in his class, most of them were female students, and most of these female students made their own crystal mud.

During the visit, the reporter also interviewed a number of parents randomly. Most parents said that they had seen their children play with crystal mud or buy DIY raw materials for their children. Some parents also said that they didn't let their children play because they knew that borax in the crystal mud was poisonous. According to Ms. Zhao, who picked up the child, she didn't know that there was borax in the crystal mud before, and she also bought raw materials for making crystal mud for her daughter. Later, a colleague told her that a child was poisoned by eating borax by mistake, and she realized that the crystal mud was unsafe and would not let the children play again.

"We don't let children play, but there are still many children playing at school. You can buy it at the school gate, and you can't stop it! " According to another Mr. Zhang who picked up the children, borax is poisonous. After playing with crystal mud, children don't wash their hands to eat or eat snacks, which is not good for their health and they are also worried.

Is there any relevant department to supervise the sales of borax, a chemical product? The reporter has consulted the Third Safety Supervision and Management Office of Zhengzhou Safety Supervision Bureau and the Raw Materials Industry Department of Zhengzhou Industrial and Information Committee. But the answer is that borax is not a dangerous chemical and is not within the scope of safety supervision. The raw materials department of the Industry and Information Committee is only responsible for the management of steel, aluminum and aluminum processing, nonferrous metals, building materials, refractories and other industries, and borax is not within their management scope.

Finally, the reporter reflected the visit to the Jinshui District Administration for Industry and Commerce of Zhengzhou City. According to the staff of the bureau, it is definitely inappropriate for shops around primary schools to sell borax. He will immediately report to the relevant leaders and arrange for the staff to check it on site.

Here, Professor Yi Zhu also reminds parents that when children play with crystal mud containing borax, borax will be absorbed by the human body if their skin is damaged or their hands touch their mouths. Therefore, when children play with crystal mud, parents and friends must pay more attention. They can wear gloves for their children to play with and never buy "three noes" products. After playing, they should urge their children to wash their hands to avoid harmful borax residues being ingested.

Popular science knowledge

Borax, also known as sodium tetraborate, is an alkaline chemical with certain toxicity. National laws explicitly prohibit the addition of borax to food.

Intake or inhalation of borax has negative effects on central nervous system, liver and kidney. The main symptoms of borax poisoning are blue-green vomit, diarrhea and rash. Repeated skin contact with borax can also cause dermatitis.

Borax is absorbed quickly in human body, but its metabolism is slow. If children play with toys containing borax for a long time, it will cause the biochemical process of the nervous system and directly affect the normal operation of the reproductive system and endocrine system.

Making Crystal Mud Composition 500 Recently, it is popular to bring a small pink iron bucket in the class.

When you open the lid of this iron drum, you will be surprised to find that it actually contains some translucent colloidal mud similar to strawberry jelly.

This translucent colloidal mud is cool to the touch, soft, sticky to the hands, and smells like strawberries (of course, there are other translucent colloidal mud of various colors and fruits).

All the students gave this magical thing a nice name-crystal mud.

I have forgotten who brought the crystal mud to class for the first time. I only remember that when it first came to our classroom, it really caused a fanatical "crystal mud storm".

"Is this thing only in one color?" "How to play?" The students noisily asked the owner of the crystal mud all kinds of questions.

I also learned from my classmates that crystal clay is not only different in shape from ordinary plasticine, but also has age! There are two lines painted on a small iron bucket filled with crystal mud. When the bucket is full of crystal mud, it is only fragmentary. When the volume of crystal mud shrinks to a line, it grows up to one year old; Crystal mud shrinks to the second line and is two years old; When the crystal mud is put in your hand, it will never stand up and stick to your hand, and it will come to the end of life.

Naturally, I "threatened" my parents and asked them to buy me such an attractive bucket of crystal mud at once, but only if I made sure I got good grades in this exam.

In the process of playing, I found that crystal mud actually has the ability of self-recovery.

Once, a classmate was playing with my crystal mud. Inadvertently, the crystal mud fell to the ground and split in two.

She looked at me apologetically and apologized again and again.

Although I didn't blame her, I was still trying to find ways to restore the crystal mud. When I got home, I put my ideas into action, but they all failed.

Just when I was sad, the light flashed-I poured the crystal mud back into the iron drum, tightened the lid, and then kept shaking the iron drum.

A few minutes later, my hands were sore. I opened the lid and looked-ah! The crystal mud has recovered! I am so excited.

In fact, there are many characteristics of crystal mud waiting for you to discover. Please join the Crystal Mud Family as soon as possible! ...

How to make crystal mud with space sand? My family grows many small plants, such as cactus, cactus, rich tree, aloe and so on.

My favorite is the green radish.

Green radish is a plant that can be raised in water and mud. My mother said that keeping it in mud would attract mosquitoes, so my mother chose to keep it in water.

If you raise it with water, you should raise it with crystal mud. Crystal mud is rich in nutrition, and green radish can grow stronger.

Through careful observation, I found that a green radish is connected by a section of green stalks, and each section of green leaves is staggered. If a stem is broken and planted in a flowerpot, it will continue to grow, and I think its vitality is very tenacious.

There used to be only one pot at home, but now there are three pots.

Green radish can absorb turbid air and release fresh oxygen.

Dad said, "putting some green radish in the newly renovated new house can purify the air."

"The green color of the green radish adds vitality to our room.

Reading while I am doing my homework can also protect my eyes.

These humble green radish brought me a lot of happiness, and from then on, green radish became my favorite plant.

The ratio of washing powder to water is 1:3. If there is too much washing powder, the color of crystal mud will be darker. If there is less washing powder and more water, the crystal mud will be sticky, so the ratio of water to washing powder must be appropriate, and then stir? Then add liquid glue, and the proportion of liquid glue is related to the amount of crystalline soil you want to make.

? Then stir on both sides, don't turn around. If you stir in circles, the crystal soil will be very hard.
