Almost everyone can grow a crystal. The main thing is to have the necessary knowledge to conduct the experiment correctly. A similar practice is carried out in some schools in chemistry lessons. Of course, there are certain rules that cannot be ignored:
- Crockery used for growing must not be used for eating food.
- You only need to use reagents that you know.
- Do not eat or drink while growing.
- Materials and resources for the experiment should be stored in an airtight dry place. Giving them to children or animals is strictly prohibited.
- The experiment is carried out in a separate, closed room with gloves and protective clothing.
- If the solution comes into contact with the skin, the area should be rinsed with water. In case of contact with eyes, consult a doctor immediately.
- Keep your workplace tidy.
As you can imagine, all these rules are necessary for growing a crystal at home successfully, without undesirable consequences.
For cooking, you need a glass container and a substance from which the crystal will grow. For those who conduct such experiments for the first time, it is recommended to use salt or copper sulfate. The first one can be purchased at any grocery store, and the last one - where fertilizers for summer cottages and vegetable gardens are sold. Also, both can be purchased at chemical stores.
The experiment itself is carried out as follows:
- The substance is placed in hot water in small portions. The reagent is stirred until a concentrated solution is obtained. Its main feature is that the substance will stop dissolving.
- The resulting solution is cooled and after half an hour is filtered using a funnel and a piece of cotton wool. The procedure is repeated a day later.
- A seed (small crystal) is placed in the solution. After 3 days after that, small crystals form in the container, which will prevent the growth of the main one. To get rid of them, the liquid is filtered and poured into another container. The main crystal is also placed there.
- Gradually, the liquid in the container evaporates, and the seed begins to grow. If it just lay at the bottom, the direction of growth would be limited from below. If the crystal is brought in at the very beginning on a copper wire, only the walls of the vessel will be a limitation. When all the liquid has evaporated, a crystal remains in the container at home.

To grow crystal from salt, a sufficiently strong salt solution must be prepared first. The salt is added to a glass of water until it stops dissolving during stirring.
Now the resulting mixture should be heated in order to achieve complete dissolution of the selected salt. A glass of brine is placed in a container of hot water. Then the resulting concentrated salt solution is poured into a special glass or container. A crystal "seed" - a crystal of table salt - is suspended on a string in the glass with the help of a jumper (it can also be from a ball rod), so that it is completely immersed in the resulting solution and does not touch the walls of the beaker. Also, the crystal can be lowered to the bottom of the glass. Your future crystal will grow on this "seed". The container with the saline solution should be placed in a warm place and left open. Wait for a while to grow a crystal from the salt. After a few days, your crystal will grow significantly in size. Three days after the start of the experiment, the thread with the "seed", immersed in a concentrated saline solution, will turn into a "necklace" of crystals. If you want your crystal to grow even faster, you need to repeat the procedure for preparing the solution. Your "seed" can be placed in a new salt solution and added to the required portion of table salt. It must be remembered that the saline solution must be highly concentrated - during the preparation of the mixture, salt must remain at the bottom of the beaker. For example, in 100 ml of water at a temperature of 20 degrees Celsius, you can dissolve about 35 grams of table salt. As the temperature rises, the solubility of table salt increases. When your crystal grows to the desired size, it should be pulled out of the solution and dried with a soft cloth or paper towel. Then the thread is cut, and the edges of the crystal are covered with a colorless varnish, in order to prevent it from "weathering" in the air. Using this method, you can table salt of any shade or shape.

Grow NS very simple - after all, in any home there are products with a crystal-like structure. These include, for example, sugar or salt. With their help, you can create crystals in a wide variety of sizes. But be patient: this process will take about a week.
You will need
- Pot
- Half a glass of sugar or salt
- Beaker
- Metal cup
- Gauze
- Charcoal
Instructions
Cover the growing crystal bowl with a piece of gauze to prevent dust from settling on the surface of the liquid. Place it where it will not bother anyone.

Of course to grow crystal diamond in home conditions is impossible. But here's to get very beautiful on your own crystal salt is quite possible. Since it is fragile and afraid of water, it will have to be stored in a transparent box.
Instructions
Decide whether you need the correct one or if some of its deviations from the correct form are allowed (sometimes the latter even turns out). In the first case, the water should be distilled, and the salt should not be iodized. In the second case, use tap water and any table salt.
Boil about half of the water. While it is boiling, carefully so as not to scald, start pouring salt into it. To do this, you can use, for example, a V-shaped piece of metal, keeping your hands away from the vessel. Continue adding it until the solution becomes oversaturated (small crystal iki salt).
One of the largest crystal Separate and hang on a string.
Pour the oversaturated solution into a clean vessel so that small crystal from the walls of the vessel in which boiling was carried out. Let it cool, then put in the solution crystal ik on a string. It should not touch the bottom.
Leave the container in a place where it will not be moved. Small crystal uk will gradually increase in. When it reaches the size you want, remove it, then dry it thoroughly and transfer it to a transparent box.
Make a backlight device if desired crystal and LEDs. What it will be depends on yours. You can highlight as one large crystal, and somewhat smaller ones. In the latter case, they can be used to make a composition composed not only of crystal s, but also from others. Do not forget to add a background and cover the composition with glass, as from touch crystal you get spoiled.

From about four to seven to eight years in life, there comes a period when he develops an attitude towards life and self-confidence. During this short time, parents need to do a lot to raise an independent, successful person from a baby.
Instructions
A socially successful person is unlikely to grow up in a family where a passive, consumerist attitude to life flourishes, where self-esteem is low. Remember that children learn by watching you. Try to be your baby's role model. If close people are honest with, he learns justice from them and will certainly be honest with them. If the parents are successful, and the baby will strive for success.
In order to develop healthy self-love and form the right one, a child needs to know that he is loved and cherished, that he is the way he should be. Children need to feel that their parents are proud of them and do not regret that they were not born different. Remember: neither expensive toys, nor other gifts and material benefits can replace your parental involvement in his life, attention and love, which allows you to feel your worth.
Remember that multiple prohibitions usually do not help you achieve the desired result. The kid will be all the other way around, annoying his parents, or will take it as a rigid instruction for life, forming an inferiority complex. And it is incompatible with success.
One of the main tenets of a successful, self-confident is "My opinion is important to others." And the little man should know this. Do not treat any of his problems down-handedly and condescendingly, but seriously and in a friendly way. Try to communicate with your child as equals, encourage his independence. But always offer your child your help when you see that he needs it.
