This type of toy was reported on Beijing Channel 7 and is called "Water Elf". Because the parents were concerned about its safety, they consulted the relevant departments.
Experts explained: This is not a living toy. thing, but a very water-absorbing animal. Gelatin, a strong substance, will swell or even burst (split) when placed in water.
The following is a detailed report cited:
Xinjiang News Online News on October 10: A The so-called "water elves" really attracted the attention of many citizens because of their bright colors. Many people couldn't resist the sellers' boasts and bought a few to take home. Huang**, who was very curious, returned home and did a simple experiment to reveal this beautiful lie.
On October 8, in Xiaoximen, Urumqi City, a vendor was loudly selling water elves to passersby. In the poolwhite porcelain filled with water in front of her, there were many colorful water elves. The journalist tried to touch it, but was immediately stopped by the seller: “They are living beings. If you touch them, you will kill them. » According to him, it is an artificially cultivated mushroom, similar to underwater mushrooms. mushroom, its texture is soft, non-toxic and non-polluting. To the touch, it feels like jelly.
In addition, each water elf also has colorful balls inside its body. "No, they're not little balls, they're water elf eggs." The seller said that as long as the water is changed every three days, these colorful eggs will "lay". There is no need to feed them. All. Simply change the water once every three days.
Is this dollar water elf really a living mushroom? If so, how can it survive without food? How could it take the form of diversits creatures such as starfish, dinosaurs, pigeons, etc. ? Huang**, a citizen who studies food additives, is quite confused about this.
"Out of curiosity, I bought three and used a knife to dissect the water elf when I got home." When Huang** cut it in the middle with a knife, clear liquid flowed out. From her experience, she thought it was something like gelatin.
Then Huang** soaked the gelatin at home in tap water, poured the liquid into the mold, and then dipped the entire mold in calcium chloride liquid which acts as a water retention agent. After cooling, the water spirit is born. Huang** said that edible gelatin is actually the raw material for making jelly, and it can also be replaced with an additive called sodium alginate, so that the water elf looks like jelly. frozen when youtouch with your hands. The so-called “egg” is also made using this method.
It is understood that if industrial raw materials are used to process “Water Elf”, it will be harmful to the body. Making “Water Elf” is very simple. If parents are interested, they can buy some ingredients and make it with their children.

Why are inflatable water toys becoming smaller again
< strong> See the production method below:
The first tools we need to prepare are batteries, magnets and copper coils. Place small magnets with the same pole (both N or both S) attached to the positive and negative terminals of the battery, respectively. Next, place the prepared battery into the copper coil. At that moment, you will noticez as the battery continues to shuttle in the copper coil.
The small magnets are the key point of this experiment. They not only generate a magnetic field, but also act as conductors, connecting the copper coil to the positive and negative poles of the battery even if there is current. generated in the copper coil, at that time An energized copper coil generates a magnetic field according to the laws of electromagnetic induction and the right-hand rule.
Since the material of the inflatable water toy can combine with water, when it becomes smaller, the original material inside will decrease, so it will become smaller.
Inflatable animal toys are made from super absorbent polymer materials. The principle is to use functional polymer materials to increase their volume after absorbing water. Once the expansion toy absorbs water and expands, itsvolume is 600% larger than the original size. It has independent plastic packaging, bright and beautiful colors, exquisite and realistic workmanship, and the expansion effect is particularly good.
