Child joy. The spinning top is one of the favorite toys of kids. Some designs allow you to exhibit astonishing physical effects. The following illustrations show three of the top. The first of them is horizontal, it can be in two variants. Option And unwinds the palm of the hand, and the second (B) — thread (Fig.1); in both cases, the disk begins to rotate around the vertical axis. If the plane is to glue strips of colored paper, respectively, during rotation of the gyroscope can be observed, for example like colorful stripes “disappear” and the paper appears white, and black-and-white figures are converted into colored rings.HIMSELF A MAGICIAN

The proposed distribution network of the other transformable design for sleep have one common not wealth: they allow you to rest only in “Spartan” conditions. Meanwhile, this disadvantage can be overcome. The source data used in the development of the proposed homemade of options had the following characteristics bed: the minimum length of 1900 mm, width not less than 750 mm and height up to the surface of the mattress is not less than 300 mm. Such a retractable bed is relatively simple in manufacture and can perform certain functions both assembled and unassembled.
Loggia, balcony — a kind of additional area of the apartment. However, it is not particularly large, but how efficiently we use these “extra” square meters? After all, a reasonable approach here is simple to organize the area in the summer (even put up a cot for sleeping), mount the Cabinet to the tool, household items, sports equipment. Finally, to equip a place for carpentry and plumbing work. How to do it?
The water treated by an electric current, acquires new properties: some of it manifests itself as a weak alkali solution and the other acid. When activated in this way the water felt on animals and plants, it was found that the liquid with alkaline properties were the stimulator, and one that bears signs of acid inhibits the growth of microorganisms and cells of living tissue.
Executive car GAZ-12 (ZIM). The names of Soviet aircraft were assigned, usually by the name of their chief designer. Created by C. A. Yakovlev received the name Yak, Mikoyan and M. I. Gurevich – MiG, S. A. Lavochkin – La, P. O. Dry – su, A. N. Tupolev – Tu. Well, the names of the cars have never been associated with the names of their designers, and so few people know who was A. A. Lipgart, N. A. Astrov, V. A. Grachev or B. M. Fitterman.
In apartments with paired window units no of vents: the role of narrow casement Windows. This is justified in summer, and then only in good weather; in rain, if he is still with the wind or sideways across the transom is filled with water. In the winter and very uncomfortable: wide open — cold and slightly open in a narrow slit through the frosty wind. That is why often the top of sash major redesigns for ordinary window.
Records of poultry ka large poultry farms and in the farms is no easy task, without automation is not enough. This operation can be performed using the microcalculator B3-23. It is necessary only to add the connector through which the electronic device is connected to the sensor (see Fig.) — associated with a movable strip contact pair S1 (see diagram). 
To drive in many modern pneumatic machines and tools required compressed air pressure of 3-4 ATM. Is it possible to build a mechanism which effectively would have used a pressure slightly above atmospheric? It turns out that modeling proves it.
