The first thing that comes to mind after Novoselov obtain a warrant for the apartment – such as drilling holes in concrete walls, how to attach the hooks to the asbestos cladding? Meanwhile, a variety of designs, there are many traffic jams, and you will always be able to do any of them, taking into account the thickness and strength of the wall, its technical capabilities and the number of required hooks and screws. The simplest option – all known wooden plug of solid wood. Its cross section should slightly exceed the diameter of the prepared hole. Cork hammered with a hammer, then drill its center, thinner than the intended nail or screw, nasverlivaetsya hole. Unfortunately, such plugs do not always provide sufficiently reliable fastening: wood rassyhaetsya from time to time, and seemingly firmly reinforced eaves curtains or favorite printmaking fall on your head.
Housewarming note
Double snowmobile “SQUALL-3”. With the advent of motoparaplane and trikes culture of designing power plants with propellers significantly increased, and today Amateur designers create rotor setup with decent traction engines using relatively small power. Accordingly, began to appear more frequently and wingless versions of these vehicles – hovercraft, snowmobile and aerolizer.
The state of the Soviet cruise fleet in the early 30-ies of the last century can hardly be described as sad. The last ships of this class light cruisers of “Svetlana” have not been completed. Of the remaining into operation relatively quickly introduced, only one unit in the Baltic and the Black sea — “Red Crimea” and “Chervona Ukraine”, respectively. The third “lucky”, and with a much more interesting shipbuilding fate, became the “Admiral Lazarev”. Ship, ready to 1918, nearly 70%, after the revolution, became the object of various plans. In 1924 the Council of Labor and Defense passed a resolution on the completion of the cruiser with the installation of eight 203-millimetrovogo taken from old ships that are not subject to recovery. However, in the following year, Soviet designers started to create a fundamentally new naval gun. Original it was almost all starting caliber. 
In one of the rooms “M-K” in the report from the championship of Russia on model rockets, I noted the rocket plane category S4 Nikolay Tsygankov team in Murmansk region. I must say that the chosen scheme with a large wingspan (about 950 mm) and elongation of about 20 provides good performance as well. This contributes to the convexo-concave profile of the wing, and elliptical shape of the bearing surface when viewed from above. And external contours of the tail look perfect. All this allows to a minimum to reduce aerodynamic drag. Originally decided N. Tsygankov and the problem of drag reduction during takeoff model. He used double-folding “ears” (consoles) of the rocket and to prevent the occurrence of flutter of the fixed wing is folded in three points (instead of the usual – in two points), securing the third hook-latch on the tail boom.
