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

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.

When threading in duralumin or aluminum, failure can 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.

Surely you have heard about growing crystals at home from various 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

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.

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.

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 -

There are quite a few ways described on the Internet how to etch a circuit board in a solution of ferric chloride or hydrogen peroxide with citric acid. At the same time, another etching method is undeservedly forgotten - in a solution of ammonium persulfate. is he

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.

I will show how to make a simple and cheap water-repellent or moisture-proof coating - liquid glass. Motorists have been using it for a long time, covering them with headlights, glass and all the pieces of their car. This coating is relevant especially in the spring-autumn

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 to restore the surface of the metal does not require any scarce reagent or

Distilled water has a fairly large use in everyday life, which I personally did not know about. I just used distilled water only for refueling. Although this is not limited to its use.

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. Mostly burnished is used as a decorative

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 in the end will be

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

Of course, this is not really a pepper spray, but rather a pepper spray. Which you can use for self defense. You can buy this and ready, but if you do not have the opportunity or the price is too high, then you can make pepper spray yourself.

This method of surface restoration and rust removal is suitable for those who want to return old things from steel to their normal appearance and remove traces of corrosion. Many of you must have found interesting antiques from your grandmother in a closet, or

For me, as a radio amateur, this laboratory electronic bathtub became just an indispensable assistant. If you are engaged in radio electronics, I sincerely recommend repeating it to you. I often have to make printed circuit boards. Manufacturing process

A shaker for stirring the pickling solution will be a useful device for radio amateurs practicing the independent manufacture of printed circuit boards. As the basis of the device, you can use a CD or DVD drive from a computer, with a working

I want to share some of my experiences. I have been practicing bees for five years and every year I take out my small apiary to the country house 40 km from the city. I’m leaving at the end of April and back in October, so I spend almost half a year in nature with my pets.
