Today we will talk about chewing gum for hands. In this article, you will learn what they are, what they are, how to make them yourself, where to buy and how much they cost.
Gum for hands is a plastic mass(inorganic polymer), which easily takes any shape, wrinkles, stretches, breaks and tears. This mass has several names:

- it's not the same thing. Gum for hands has a denser texture and has a number of contradictory properties:
Gum for hands can manifest itself as a liquid and as solid(properties of a non-Newtonian fluid). In the first case, the property manifests itself when you act on it slowly or not at all - it becomes malleable or blurs. In the second case, the handgam, when you act sharply and apply force, breaks, breaks or jumps.

Sometimes manufacturers combine several properties in one toy.
This polymer was a by-product of an experiment to produce a synthetic rubber substitute. But after he was used in the form of toys for children. Fans of smart plasticine have come up with another several ways to use:
Doing something with your own hands is very interesting, and in the case of smart plasticine, there are a number of pluses:
You can add various decorations to homemade smart clay, such as sparkles, beads, hydrogel balloons and figurines.
A handmade handgam will deteriorate faster than a store-bought one (shelf life is about two weeks), and it will not have all the properties, for example, it will not be possible to break it, and it will bounce worse.
What is needed for this:
A visual recipe for handgam from glue and sodium tetraborate
Pour the glue into the container, add flavoring and coloring as desired. After, gradually add the thickener in small doses, stirring constantly and thoroughly. This recipe is good because, firstly, almost everyone already has these ingredients at home (sodium tetraborate is sold in a pharmacy), Secondly, after preparation, you can immediately play with the handgam.
You will need glue (either silicate, or liquid PVA from Luch, or polymer Titan), toothpaste(helium is best), a container and a mixing stick. This handgam will have a pleasant smell.
Mix ingredients ( One tablespoon of glue comes with half a tube of toothpaste), then refrigerate for at least six hours (this procedure is necessary so that the toy does not stick to your hands).
The method is fast and safe. cook glue (as in the example above), starch(you will need liquid, you can dilute dry starch with water or buy already liquid) and, if desired, food coloring. Mix liquid starch and glue in a ratio of 1: 3, then add a pinch of dye. Stir until smooth and leave in the refrigerator for five hours.
This recipe is a little more difficult than the above. What do we have to do:
After cooking, put in the refrigerator, before starting the game, wait a day.
Recipe for a hard handgam that can be inflated
Gum for hands are original and non-original (imitation).
Original sold in large shopping malls and in online stores. There are different sizes:
There are also large sets. Nanogam cost not less than 80 rubles(+/- 10 rubles), and the maximum prices reach up to three thousand rubles.
Non-original can be found in any toy store. Such chewing gum for hands is much inferior in quality, often they do not stretch well, do not break and do not jump. But they are much less expensive from 15 to 100 rubles.
The forefather of chewing gum for hands is the Scottish scientist James Wright. In 1943, in his laboratory, he worked on the invention of synthetic substitutes for natural rubber. And during one of the experiments, he received a bright coral polymer with interesting properties. The substance did not stick to hands and other surfaces, did not leave stains, did not hold its shape. True, in which industry to use such material, at that time they did not come up with. Modern manufacturers have found a scope for this polymer. They turned it into an educational toy. Since then, the invention of James Wright has become known throughout the world. In 2001, it was inducted into the US National Toy Hall of Fame.
Handgum has many properties. For example, if you roll a ball out of it and immediately throw it on the floor, it will jump like a real rubber ball. And if this ball is put on a flat surface and wait a few minutes, it will spread and turn into a cake. Place the gum on the grate and it will drip through the holes. The polymer can be pulled over the hand like a glove. In the same way, you can wrap it with any other object.
Modern manufacturers have slightly modified the invention of James Wright. And now, in addition to the classic coral chewing gum for hands, they offer customers handgams that can change color depending on temperature, glow in the dark, and also have magnetic properties. In addition, Handgum began to be made in different colors and with various smells.
It is recommended to use gum for hands as an antidepressant when it is necessary to calm the nerves. Also, with the help of "" you can train the muscles of the hands, develop the hands after fractures or bruises. Can also be used as a cell phone case. It will be shockproof and waterproof.
This toy is useful for children with diseases of the nervous system. For example, with mild forms of cerebral palsy, delayed speech development. It is believed that Handgum helps develops fine motor skills fingers, develops creative thinking, good diction. Helps correct bad handwriting. Physical exercises for fingers, which are very easy to do with Handgum, have a positive effect on brain function and relieve fatigue.
Among other things, resourceful users of Handgum began to use the toy in everyday life. As it turned out, "
Gum for hands is designed to help adults who are tired of problems relieve stress. And children, playing with such an interesting "live" plasticine, have fun and develop at the same time. However, do not allow kids under four years of age to play with such a toy without adult supervision.
Externally, slime chewing gum for hands resembles a ball of many chewing gums. It just looks brighter and nicer. The substance from which this unique thing is created does not stick to hands and does not stain the surfaces that come into contact with it.
The gum for hands stretches well and does not tear at the same time. And crushing and pulling such an interesting substance in different directions is a rather entertaining activity that really "disconnects" from problems. Even children can play with it - the substance from which the anti-stress toy is made is not poisonous. Although you do not need to gnaw and try to try.
At the dawn of its appearance, chewing gum for hands (lizun) caused some negative emotions. When such a slippery thing appeared in someone's hands, those around them grimaced contemptuously and with disgust. They didn't like the look of the substance, it was associated with something not very good. Now more and more people prefer to relieve stress and have fun with hand gum. Let's talk about interesting properties ah hendgama, as it is also called in another way:
Finding that the toy is attracting more and more people, manufacturers are not sitting still. They invent innovations to make the anti-stress toy even more interesting, and therefore more tempting. Here are some unusual ones:
This substance should not be set on fire. She can catch fire. Substance sinks in water, but does not dissolve. Do not keep the gum in a humid environment for too long if you do not want it to lose its unusual properties. Do not wash the toy with soap. Soap contains elements that interact with the mass and are able to destroy it. Fabric surface - not the best place for "hand chewing gum". It will be very difficult to remove it from a fleecy fabric. Refrigerator destroys easily beneficial features this plastic mass.
For this you will need:
Cooking technology:
If you want to make anti-stress chewing gum for children and you would like to secure the composition of the toy as much as possible, use the recipe for chewing gum for hands without sodium tetraborate. Here he is:
Hello!
I would venture to review (not to be confused with “to get around”) a slightly specific product - chewing gum for hands or Handgum (literally Handgum - hand chewing gum, English) - this is a silicone-based substance, it feels like chewing gum, but has the interesting properties of thixotropic fluids.
Particularly impressionable better photo don't look!
Material from Wikipedia
Gum for hands (Handgam, Handgum - manual chewing gum, chewing gum for hands) is a plastic toy based on an organosilicon polymer, created in 1943 by the Scottish scientist James Wright.
A polymer with peculiar properties was obtained by him as a side result of experiments conducted to obtain synthetic substitutes for natural rubber.
Hand chewing gum looks like plasticine or large chewing gum. The substance is non-toxic, odorless, tasteless, does not stick to hands and does not get dirty.
In a long period of time, chewing gum for hands manifests itself as a liquid: if you mold an object of a certain shape from it and leave it on a flat surface, after a while the substance will spread.
The substance slowly flows through the holes in large drops.
In short periods of time, the substance behaves like a solid body, for example, if you make a ball out of it and hit the floor, such a ball will bounce.
Depending on various additives, toys of different colors can be obtained, including glow-in-the-dark, color-changing, and magnetic toys.
The original gum for hands has a coral color and consists of 65% dimethylsiloxane, 17% silica (crystalline quartz), 9% Thixatrol ST (castor oil derivatives), 4% polydimethylsiloxane, 1% decamethylcyclopentasiloxane, 1% glycerin and 1% titanium dioxide.
After reading the composition, you may be scared, but here's what I found.
Characteristic
Silicone polymer is used in many industries, including medicine.
Lenses are made from it, which have direct contact with the body.
Quartz is non-toxic as it is a mineral of natural origin. Used for example in water filters. Has healing properties.
Thixotrol - hydrogenated Castor oil modified with polyamide oligomer. A non-toxic substance that is used in the cosmetic industry, has skin softening properties.
Glycerin is also non-toxic and is also used in the cosmetic and pharmaceutical industries.
So, having understood what it is, let's proceed to the experiments.
Chewing gum has a bunch of interesting properties: it flows and jumps, soft, hard and liquid at the same time, beats like porcelain and jumps like a ball, does not stick to hands and other objects.
How to distinguish a real Handgum (Hendgam) from a fake
Everywhere they write that it is impossible to break a fake with a clear cut, it will only stretch. Let's try. 
I won’t say anything, but I managed to break it, though on the 7th attempt.
Why is she to me? I bought it at the request of school-age boys I knew, well, I left one for myself for fun (I remembered the “lizuns” from childhood).
I love everything unusual) I got green color, alas, I was not given the right to choose. 
This polymer miracle weighs 25 grams, it came in a transparent plastic jar. 
Properties
Lit.
It sinks in water, but does not dissolve in it. Loses some of its properties in water.
Properties can be lost even if put in the refrigerator, but in the microwave it does not even heat up.
You can not keep it for a long time on a fabric or on a fleecy surface - it will stick and you will have to rub it with alcohol.
You can not wash with water and soap, the water contains chlorine, from which it becomes softer, with soap - it reacts.
Afraid of any chemistry.
If you hit the handgam with a hammer hard enough, it will either practically not change its shape, or it will break into many small particles.
I managed to break it into only 3 parts, and not into many parts, although maybe I was just afraid to swing a good hammer.
Chewing gum is always trying to spread. Therefore, if you give it any shape, you will be surprised at how consistently it smoothly runs away from eclecticism.
Attach the gum to a horizontal surface and see how its shape begins to change, and then the gum will flow down. 
For example, if you make a ball out of chewing gum and put it on the table, then after a while the ball will become a puddle. 
But with a quick impact, the chewing gum will behave like a solid body - the same ball thrown on the floor will bounce like rubber, though not high - about 5-10 cm.
If you gently pull the gum in different directions, then it will stretch without breaking, like hot cheese. 
Outwardly, chewing gum for hands resembles plasticine. 
Gum accumulates sunlight and glows at night, very, very faintly.
On the Internet, I also found such an application for chewing gum, they literally used it “for hands”. 
P.S How to save money and make gum with your own hands at home
Do-it-yourself chewing gum is not inferior in its qualities to a purchased one. It has the same properties - it changes its state from liquid to solid, it is easily molded, does not stick and does not get dirty.
To make chewing gum for hands, you need to take PVA glue, sodium tetraborate (you can buy it at a pharmacy) and a container where chewing gum will be kneaded.
Step one.
We take PVA glue (as much as you want to get gum for hands at the exit) and pour it into a container, preferably a glass one (a glass or a jar will do).
Step two. Pour sodium tetraborate into a container with glue. (the more, the thicker the chewing gum will be).
Here you can add dye if you want to get colored gum for your hands.
Step three.
We mix everything, put it on a napkin and squeeze out excess moisture.
All! Chewing gum for hands with your own hands is ready!
Thank you for your attention!
