How to grow a crystal of salt at home

Do you like to conduct scientific experiments and want to bring your children to this? The best way to do this is to try together to grow a crystal from ordinary salt, which everyone in the house probably has.

Safety regulations

The experiments are based on the chemical reaction of a saturated salt solution. Both cooks and seafood are used almost every day in everyday life, it will not harm you.But still try to work with gloves and a headscarf. This will prevent foreign objects from getting into the liquid - dust, hair.

If you have unprotected wounds or burrs on your hands, you need to be very careful, since the solution can corrode the skin in damaged areas and cause acute pain.

In order to grow such a crystal at home, you do not need any laboratory equipment. All you need is at your fingertips.

Regular crystals of salt should have even, large faces

Do not add natural or artificial colors. There is no point in this: the salt crystal will still grow colorless.

How to grow a crystal

So, water and salt will act as reagents in the experiment, and the equipment will serve as:

  • two containers (glasses, half-liter jars or not too large pans);
  • filter paper;
  • thread or hair.

    To grow a crystal, you will need salt, water, thread, and some kind of container.

Note! Banks or glasses should be absolutely clean. Any speck on their inner surface can be the basis for the growth of additional crystals that will interfere with the main.

Preparation of the solution

  1. The first step is to prepare a saturated saline solution. Pour water into the jar. It is desirable that it be distilled or at least purified by a filter. Fill the container with about 80%, put it in a water bath.
  2. At this time, pour salt into the jar. If you use cookery, an unpleasant surprise awaits you - various trash that will float to the surface.Gently remove it immediately or pass through the filter paper afterwards. Sea salt gets on sale, as a rule, pure.Just do not take flavored and colored with various additives, it is very harmful to the process.
  3. Salt pour with a margin to the solution turned out to be satiated. The recommended proportion is 100 g of product per 150 g of water. Part of the substance should remain at the bottom, because it simply can not dissolve. Just at this stage, pour the liquid into another can, at the same time getting rid of small debris and undissolved salt.

    Salt solution should be very saturated

Crystal embryo sea or salt

Prepare the buds on which the crystals will grow.They should be large so that you can easily fasten them on a string.

The easiest way to do the selection is as follows: sprinkle salt in the salt shaker and shake until all the small crystals fall out. Those that did not pass through the holes of the saltcellar and stayed inside are great for our purpose. Choose the largest one, with a shape close to a rectangle, with a minimum of deviations.

Try to choose the largest and even crystals as an embryo of the future crystal

Secure the selected embryo on a string, and in turn, wrap it on a stick or pencil, so that over time it will be easy to adjust the depth of immersion.

There comes the main and the longest phase of the experiment. Immerse the buds in a saturated solution, poured into the second can, wrap the container with something warm, so that the liquid cools more slowly.

If the solution was sufficiently saturated and clean, the germs will increase slightly in a day. Otherwise they will dissolve.

Now cover the jar with paper to avoid dust and dust, and leave for 3-4 days. The water will gradually evaporate, and the salt will precipitate, growing on the germ and ensuring the growth of crystals.

It is at this stage that mistakes made during the preparation process can appear. For example, you could incorrectly fix a thread loop on the crystal, and it just grows into the middle.To avoid this, attach the embryo not in a bundle, but in a thread loop, both ends of which are brought out.After the growth process is over, squeeze alternately at the ends of the loop to loosen the sticking, and remove the thread.

You can set any shape of the crystal during growth.

If you want to grow a crystal quickly, then after a few days get it out of the tank. Over the past time, it should already increase in size. Prepare a new saturated salt solution and lower the crystal there again.Some experts advise simply to fill the required amount of salt in a jar and mix thoroughly.

As you can see, growing a crystal is not so difficult. The main thing is to adhere to the technology and follow the recommendations. Despite the fact that this process is not fast, you end up with beautiful souvenirs that can be used as a decoration or a gift.
