Fascinating chemistry

I was just bewitched when I repeated this beautiful and exciting experiment! It does not contain hard-to-reach reagents, all the components are in the kitchen - it is baking soda and vinegar. This experiment is called "hot ice." It can be repeated by anyone! We need: - 1 kilogram of vinegar 70%.

I show you a simple and funny chemical experiment. We used to do it at school, just take salt and grow salt crystals. In the same example, we take sugar and grow crystals from it. It will be a candy, which at the end can be eaten, which cannot but rejoice. The ingredients that are needed for the preparation of sugar crystals are 380 ml.

Burnishing is the process of producing an oxide layer a few microns thick. It is also called oxidation, blackening or blueing. This is a dark, almost black coating, but there are other shades. Basically, burnishing is used as a decorative coating, but initially, in the first place, it is intended to protect steel from corrosion.

I am sure that most people use aspirin in limited cases. Such as a headache, with fever, with a cold, etc. I dare to assure you that the use of aspirin is not limited. For example, aspirin can moderate a heart attack. Aspirin fights blood clotting, as a result of which it slows down the trambocytes.

This is one of the easiest, safest and most effective ways to remove rust from the surface of old steel tools. The difference between this method is that for the restoration of the surface of the metal does not require any scarce reagent or expensive equipment. All that is needed is in almost any kitchen.

Our home-made handgam in almost all properties matches the one sold (it flows, breaks, stretches, jumps) Components: Sodium tetraborate; PVA glue; Dye; A jar where you can mix everything. Production: 1) Pour PVA into the prepared jar 2) Add dye, in my case it is brilliant green. Stir well.

Jewelry gas welding machine on plain water. Hydrogen, when mixed with air, forms an explosive mixture - the so-called explosive gas. The combustion temperature of hydrogen is 2800 degrees. Celsius. It is on these facts that this gas welding is collected. The basis of welding is an electrolyzer, which is charged with a solution of alkali in water, i.e.

Today I will show you how to make a home nuclear reactor. I hope you have a good sense of humor, then let's get started. To build a mini reactor you will need a glass jar. Copper wire with a diameter of about 1 mm. Preliminary, remove varnish insulation from the surface of the wire. In the role of thermonuclear fuel, simple acetone will be used.

As you know, metal is quite difficult to process at home without special skills and tools, especially if it is such a solid metal as steel. Nevertheless, you can call for help chemistry: there is such a chemical process - electrolysis. It flows on the electrodes when an electric current passes through electrolyte solutions.

This is a fun, beautiful and entertaining chemical experiment that can easily be repeated at home. All reagents are available in almost any kitchen, and if not, then you can definitely buy them at any grocery store. I will show how to make some kind of lava lamp, but unlike the real one, it will start working immediately and will not require heat to continue the reaction.

The experiments on the extraction of precious metals from boards, microcircuits, transistors and other radio components are no longer new, and they are hotly discussed on the Internet. Many thus discovered talented chemists in themselves, and someone makes good money. Interest in this topic fuels the desire to get valuable metal from worthless elements, many of which are deposited in pantries in workshops, office sumps and even litter in trash.

Good afternoon! Surely you have heard about growing crystals at home from various kinds of reagents: iron or copper sulfate, sodium chloride, citric acid. The color of the crystal depends on the reagent. This time we will grow beautiful black crystals from copper acetate. But first, let's get copper acetate itself (and our crystals will grow in the resulting solution).

A homemade alcohol burner can come in handy, say, while fishing, camping, in the woods. With it, you can reheat food or boil water. It can also be used in various other experiments and experiments. Filled with alcohol, it does not give soot and foreign smell, and due to the small size it can fit almost anywhere.

Remember how in an old Russian fairy tale: in order to revive a hero, you need to sprinkle him with "dead" water, and then drink it with "live" water. Today, "living" and "dead" water is neither fiction nor fiction. Of course, it is literally impossible to revive or kill someone by the action of such water, but such water does have healing properties.

When threading in duralumin or aluminum, failure may occur and your tap will break, leaving a chip inside the hole. Drilling tool steel from duralumin-aluminum is incredibly difficult and this means that the entire hole will be broken. There is a way in which the hole in the workpiece remains intact, and the chip can be removed without much difficulty.

Good afternoon! In this article, we will consider the process of electrochemical deposition of copper on conductive surfaces, and also try to coat a walnut with a copper layer. It will be required So, for the experiment we will need: Non-metallic container - a beaker or an ordinary tray, the deposition process will take place here; Water, preferably purified; Copper sulfate (sold in stores for a summer residence); Acidic electrolyte for batteries (in car dealerships); Charger at 5 volts, 0.

When fishing, camping or camping, it can happen that drinking water has become unusable. Or ended, or spilled - it does not matter. In general, you can draw water in the nearest body of water, boil it, wait until it cools down and calmly get drunk. But in my opinion, this is a long time. It is much faster and more efficient to use a pre-made, self-made carbon filter.

This is my favorite method of removing rust from heavily corroded metal products. The method is very simple and highly effective. With a little patience, you get impressive results. Use this method only in the open air, as highly toxic gases are released during the process.

Aluminum is a very attractive metal for constructing some kind of home-made structures: lightweight, perfectly machined, drilled, sawn, does not rust, etc. But here's the problem: to weld two pieces of aluminum without special argon welding is almost impossible. And the equipment for such welding costs more than one thousand rubles.

In such a simple way, you can make not only a round hole in red-hot steel, but also a hole of any other shape in without too much effort. The chemical method will help you out and facilitate the task. The method does not require expensive chemicals, all the ingredients can be found in any household. Will be required. I offer a simple way to make holes in high-speed steel.
