How to make a barometer with your own hands

Today many houses have a barometer. In some cases, this device is simply irreplaceable. A fan of fishing this simple adaptation allows not only to determine the weather, but also whether it will be biting. Alas, there is not always an opportunity to purchase a device. But you can make a barometer with your own hands from improvised materials. In fact, there is nothing complicated in this. It is much more difficult to make an electronic barometer with your own hands. In this case, some skills and some tools are required.

How to make a barometer with your own hands

There are several methods for manufacturing such devices. Each of the methods of manufacturing the device has not only advantages, but also some drawbacks. This method is considered the simplest. However, it is not always at hand to find everything that is required for this. To make a barometer, you need:

1. Glass transparent bottle.
2. A tube of glass.
3. Bung.
4. Water.

How to make

To make a barometer with your own hands, you need to prepare all the necessary details in advance. First you should fill a bottle with 1/3 of water. It is best to take distilled. Regular water will blossom after a year. If desired, the liquid can be slightly tinted.

After that, in the cork it is necessary to make a hole and insert a tube of glass into it. Place the joint must be smeared with clay. This will seal the hole. The bottle should be plugged with a stopper. As you can see, everyone can collect a barometer with their own hands.

How the device works

Of course, in order to understand the performance of such a device, it is necessary to know its principle of operation. Here, too, everything is extremely simple. When changes in atmospheric pressure occur, the level of water in the tube begins to fluctuate. Of course, this is not enough. You need to know when the weather is clear and when it's rainy. So, if air bubbles come out of the tube, then the pressure is quite high. This indicates that the weather will be clear in the near future. It is at this time that active biting is observed. If the water gradually flows through the tube, this indicates a low pressure. Accordingly, the weather will be rainy. You can not go fishing, as there will be no biting.

The device from the old paw

The barometer for your own fishing can be made from a burnt out bulb. To make it you will need:

1. Burnt out bulb.
2. Screwdriver.
3. Machine or sunflower oil.
4. Medium-grained sandpaper.
5. Copper wire.
6. Vice.
7. Water.
8. Ink.

Make a hole

To make a barometer with your own hands from a light bulb, you need to make a hole in it. It is necessary to work extremely cautiously, as the balloon can crack at any moment or break. The hole must be made in the place where the base with the threaded part begins.

There is a fairly simple method. First, make a note of where the hole will be made. Here it is necessary to drop a little sunflower or machine oil. Of medium-grained sandpaper you need to remove a little abrasive powder. The resulting material should be added to the oil drop. The result should be a viscous mass.

In the case of a screwdriver or a drill, a piece of copper wire should be inserted . Its diameter should correspond to the dimensions of the future hole. The plinth of the paws should be clamped in a vice, and the flask - wrapped with a rag or towel. Drill need very carefully, with a minimum of effort.

What to do next

The capacity for the barometer is ready. Now you need to fill it with water. For this purpose it is better to use distilled. The flask must be filled with water halfway. After that, the liquid should be tinted. To do this, you can drip a few drops of ink into the water. If they are not in the household, you can put a piece of slate into the liquid, preferably from a chemical pencil. After this, the resulting composition must be mixed. The barometer with its own hands is made of a burned-out light bulb. It will be possible to hang the device between the window frames. It is best to place a barometer on the north side. Here, the sun will not fall on the device. If the windows are located on the south side, then the barometer should be placed at the top of the window. Use such devices should be exclusively in the warm season, when the temperature is above zero.

How does a barometer from a light bulb

A few hours after the installation of the barometer it will be possible to take readings. Of course, you should know how this device works. If the inner walls of the bulb are covered with crayons of condensed water, tomorrow it will be cloudy. However, there will be no precipitation. If drops of medium size and between them there are dry vertical bands, then tomorrow there will be variable cloudiness. This, of course, not all. If the large drops partially cover the flask - there will be short-term precipitation, the drops are large and will drain down - there will be a thunderstorm.

With the help of such a device, you can predict and dry weather. If the walls of the flask are dry and even without droplets and fog, tomorrow it will be clear. If the condensate formed on the north side of the tank, then tomorrow, about the second half of the day, it will rain.
