This is a fun, beautiful and entertaining chemistry experiment that can easily be repeated at home. All reagents are available in almost any kitchen, and if not, then they can definitely be bought 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 hard metal as steel. However, you can call on chemistry to help: there is such a chemical process -

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

Today I will show you how to make a home nuclear reactor. I hope your sense of humor is okay, then let's get started.To build a mini reactor you will need a glass jar.

I will show you how to make a simple and cheap water-repellent or moisture-proof coating - liquid glass. It has long been used by car enthusiasts, covering headlights, windows and the entire body of their car with it. This coating is relevant especially in spring and autumn.

This is one of the simplest, 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 metal surface you will not need any scarce reagents or

Good afternoon Today we will talk about an original night light that will serve as an excellent decoration for your windowsill. So let's get started! The basis is an ordinary 100-watt incandescent light bulb.

Burnishing is the process of obtaining a layer of oxide several microns thick. It is also called oxidation, blackening or blueing. This is a dark, almost black coating, but there are other shades. Basically, bluing is used as a decorative

I'll show you a simple and funny chemical experiment. We used to make it at school, just take salt and grow salt crystals. In this same example, we will take sugar and grow crystals from it. This will be a lollipop, which at the end you can

I was simply mesmerized when I repeated this beautiful and exciting experiment! It does not contain hard-to-find reagents; all the ingredients are in the kitchen - baking soda and vinegar. This experiment is called "hot ice". He can be

Of course, this is not exactly pepper spray, but rather pepper spray. Which you can use for self-defense. You can buy one ready-made, but if you don’t have the opportunity or the price is too high, you can make pepper spray yourself.

This method of restoring the surface and removing rust is suitable for those who want to return old steel items to their normal appearance and remove traces of corrosion. Probably many of you have found interesting antiques in your grandmother’s closet, or at

This laboratory electronic bath has become simply an indispensable assistant for me, as a radio amateur. If you are involved in radio electronics, I sincerely recommend that you repeat it too. I often have to make printed circuit boards. Process

A shaker for stirring the etching solution will be a useful device for radio amateurs who practice independent production 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 experience. I have been keeping bees for five years and every year I take my small apiary to a dacha 40 km from the city. I leave at the end of April and back in October, so I spend almost half the year in nature with my
