How to draw a horizontal line without the level
There are many cases in life when it is necessary to determine the horizontal position. Typically, this is done with a level gauge (level). If it does not, you can use two glass tubes connected by a hose. He poured water, the level of which should be visible in the tubes. This device is even more convenient than the level of the spirit, especially in cases where it is necessary to lay the foundation under the house or lay a forgery, etc. Do not just allow the hose to create air bubbles that distort the meter reading.

You can use a bowl with fringing, placing it on a controlled surface and pouring water on the fringing. You can pour water simply on the surface, if possible, or on the glass laid on it.
It is convenient to use two containers of transparent glass, for example cans, pouring water in them at the same height and placing them at opposite ends of the monitored surface. Visiting from one surface to another, as shown in Fig. 2, shows which side should be raised or lowered to the horizontal position.
