Instruction
If the dog gets lost or broken during use, get a new slider. The seller can help you with this. He will select the appropriate runner number by zipper. If the zipper is one-piece or sold by the meter, purchase as many runners as you need. For example, two runners are often placed on covers, sliding towards each other.
Look carefully at the side of the braid where you put the slider. On top of the rail, most likely, the limiter jumped off. He is holding back doggy in the top position. If the limiter has moved, correct it with pliers so that the pawl does not pop out again. If the limiter is lost, make a bartack with a needle and thread. Bartack through the edge of the braid several times. She will not let the runner jump off again.
In the case of a one-piece zipper, separate the ends of the rail a little and insert each into doggy. Gently move the slider down. He will go with effort. Do not overdo it with the pressure so as not to ruin the rails. If the slider does not want to move despite efforts, slightly straighten the slots on the dog (where the rails are inserted). slide doggy down and press the slots with pliers to their original state.
The zipper is very convenient, but in the process of using it, many are faced with the problem when the blouse or jacket breaks slider, and the zipper stops closing. Do not rush to get upset and throw away the thing, because it can be easily revived by replacing slider. This operation does not take much time and is easy to perform.
You will need
- Pliers, awl or nail scissors
Instruction
Take pliers, an awl or scissors (depending on what is at hand) and very carefully remove the restrictive bracket located above and below the zipper.
Remove the faulty slider and note its markings written on the back. For repairs, you should not use sliders from old lightning, because a breakdown can occur again. Better get a new one slider in the fabric store, in the accessories department, along with a restrictive clip that will prevent the slider from flying off the zipper.
Take slider and start inserting first into the left and then into the right half of the zipper. Make sure both parties are in slider to the limit.
Gently but firmly hold the edges of the zipper with one hand while gently pushing with the other slider forward. If you're doing everything right, then slider easily enters the "teeth" of the lightning.
In the place where the old restrictive bracket used to be, put on a new one. Carefully, so as not to break, clamp the stopper with pliers.
Test the slider for proper operation by fastening and unfastening several times lightning. If a slider effortlessly “slides” over the zipper, the operation to repair your favorite thing was a success.
Helpful advice
When purchasing a slider to replace the old one, take a few pieces in reserve, because their cost is low, and they can come in handy at any time.
If there is a desire to extend the life of the lightning, then after each wash, apply wax or a regular candle to its surface. In this case, the likelihood that lightning will give you unpleasant surprises is significantly reduced.
If you still can't replace the slider at home, don't worry. Contact any clothing repair shop or sewing studio, and they will definitely help you solve the problem.

It often happens that the dog breaks down on lightning. If you are not confident in your abilities, then it is better to go to the studio. There you will either have a new zipper sewn in or a slider replaced. But you can deal with this problem yourself.
You will need
- - pliers;
- - threads;
- - needles;
- - a new slider or an old one if it just jumped off and not deformed.
Instruction
In the event that the lightning on the product is detachable, and the dog jumped off because the limiter was lost, then simply put it in place. Insert it from above, the dog should go down with the flat side. After that, replace the restrictor.
If the doggie is deformed or lost, then you need to buy a new one. It is better not to use the old slider, because when manipulating with pliers, it can break, and in any case, after a while, history will repeat itself, and a faulty slider can also damage the zipper teeth.
When buying a slider, you need to choose it by number, which is located on the product. Also pay attention to the type of zipper it fits. Zippers are detachable, as well as tractor, twisted and metal types of teeth.
Vdev doggy on the zipper, see if the upper limiter is in order. Often the problem is that it is lost, or moved, or deformed, and from this the lightning dog jumps off. It needs to be secured to prevent this situation from happening again.
Press it with pliers, but be careful not to break it. You can replace it with a new one, but you can also use a thread and a needle. Just make a few stitches with thread right over the edge. This will keep the dog from coming off the zipper, however, it is not suitable for every clothing. If the lightning is in plain sight, then the stitches will be conspicuous.
If the zipper on which you want to replace the pawl is one-piece, then you need to act a little differently. Loosen the end of the zipper, it is often stitched, so spread the stitching a little. Remove the connecting stopper, and then carefully insert each part of the zipper into the pawl.
Slowly, without jerking, move the slider. The zipper must be fastened. Here you need to be careful that the zipper teeth do not run into each other, otherwise you will have to redo everything. Sometimes the dog moves with difficulty, this is normal, continue to lead him, smoothly and slowly.
When the zipper "closes", secure the zipper at the bottom with a thread so that it does not come apart. Then check the operation of the lightning. Several times, opening and closing it.

Every person has a desire to capture rare events or vice versa, often occurring, but very spectacular. However, even a photograph of a drop of water the first few times is not very beautiful, not to mention the fact that the first time to be able to photograph lightning at the moment of discharge.
Instruction
Set the shutter speed on the camera to a higher value, many models have this option. If not, use the "Exposure" option, it must be taken to minus, and the "ISO sensitivity" option, it must be raised, but not too much so that the photo does not become grainy. The duration of a lightning discharge is less than a second, so you cannot photograph it purely physically and you need to apply similar tricks with exposure and sensitivity (technically, with shutter speed).
Use a series of shots, almost any "soap box" is equipped with such a function. The maximum number of frames and a small delay between them (1-2 seconds) will do. This will increase the chance to "catch" a lightning bolt. Switch the lens to infinity, this is an option that adds clarity to the farthest objects of the picture instead of the closest ones.
Set the camera on a tripod stand, turn on a series of shots and wait. Shooting stops after the number of shots you specified has been taken, so you need to start the burst multiple times. Lightning usually strikes in the same place - the direction of shooting can be chosen from the first uncaptured flash. In no case do not hold the camera in your hands, but use a stand or tripod - since you are using tricks with exposure and shutter speed, the slightest movement will blur the photo.
Take a video shoot if you're trying to catch lightning during the day, as due to the use of tricks, the photo will be filled with white. The video "eats up" a lot of space on the camera's memory card, approximately 100 megabytes per minute, and therefore it is worth shooting in series, filmed for 30 seconds, and if there was no lightning, delete the video and start over. Next, by frame-by-frame processing on a computer, select images with lightning and save them as separate images.
Each of us is familiar with such a situation when the zipper ceases to function normally on clothes or shoes. Despite this, the fastener can be repaired on its own with the help of improvised means and without contacting a specialist.
You will need
- zipper, hammer, pliers, alcohol, rosin, graphite lead, stearin candle, fishing line, needle, hydrophobic lubricant, a piece of unsalted lard, a piece of wire or sheet iron, a paper clip, a machine needle, BF-6 glue.
Instruction
If the zipper starts to come apart, then you can fix it with a hammer and pliers. To do this, tap with a hammer from the inside and outside along the entire length of the zipper, just do it not too hard so as not to damage the product. After that, use pliers to reduce the gap in the lock between its upper and lower parts. A solution of rosin in alcohol, which needs to be well lubricated along the entire length of the fastener, will also help restore the zipper's performance. After a couple of hours, repeat the operation, and the lock will be like new.
In the event that the lock is too tight, then it should be rubbed with a stearin candle or graphite lead. After this procedure, the performance of the lightning will noticeably improve, since these agents play a good role as a lubricant. Fasteners on clothes, and especially on shoes, do not tolerate dampness, which shortens their service life. In order for the lightning to work perfectly, you need to periodically run a piece of unsalted lard over it. You can also use a hydrophobic lubricant that will protect the product from moisture.
It is not necessary to carry a thing for repair, the zipper in which has lost a few teeth. The situation can be corrected independently, just armed with a needle and fishing line. At the place of absence, sew the missing teeth with a fishing line, threading the needle several times in a row in the same place until the necessary details are formed. This method is also useful if the zipper does not have an upper stop and because of this, the slider comes out through the top of the fastener. In place of the stops, you can put pieces of wire or sheet iron, which you need to securely fasten with pliers.
A machine needle will help sew on the fastener if it has separated from the fabric base. The method is especially indispensable if you need to repair a zipper in a hard-to-reach place, since a puncture with a machine needle occurs only on one side.
Sew on a secret lightning a special foot that allows you to fix the toothed part of the zipper. If there is no such foot, proceed as usual, but when sewing, keep the spiral open, trying to keep a straight seam line. Be sure to attach both sides of the zipper in the same direction - from the edge of the product to the end of the cut.
If the zipper on your favorite bag or raincoat began to diverge or the “dog” (slider) flew off, it is not necessary to alter the whole thing and send it in for repair. You can try to put on the "dog" yourself, the complexity of this task depends on the density of the teeth of the zipper and the way it is sewn in.
do , the slider will fly every time it reaches this place.
Lightning has long excited and frightened people with its unpredictability, beauty and terrible destructive power. As soon as the electrical nature of this phenomenon became clear, the question arose - is it possible to "catch" it and use it for peaceful purposes, and, in general, how much energy is in one lightning.
Calculation of the lightning energy reserve
According to research, the maximum voltage of a lightning discharge is 50 million volts, and the current can be up to 100,000 amperes. However, to calculate the energy reserve of a conventional discharge, it is better to take averaged data - a potential difference of 20 million volts and a current of 20 thousand amperes.During a lightning discharge, the potential decreases to zero, so to correctly determine the power of a lightning discharge, the voltage should be divided by 2. Next, you need to multiply the voltage by the current strength, you get the average power of a lightning discharge, 200 million kilowatts.
It is known that the average discharge lasts 0.001 seconds, so the power should be divided by 1000. To get more familiar data, you can divide the result by 3600 (the number of seconds in an hour) - you get 55.5 kWh. It will be interesting to calculate the cost of this energy, at a price of 3 rubles per kWh. it will amount to 166.7 rubles.
Can lightning be tamed?
The average frequency of lightning strikes in Russia is about 2-4 per square kilometer. Given that thunderstorms occur everywhere, a large number of lightning rods will be needed to "capture" them. As a source of energy, only discharges between charged clouds and the earth can be considered.To collect electricity, you will also need high-voltage large-capacity capacitors, converters that stabilize the voltage. Such equipment is quite expensive, and calculations have been repeatedly carried out proving the inefficiency and unprofitability of this method of generating energy.
The reason for the low efficiency lies, first of all, in the nature of lightning: during a spark discharge, most of the energy is spent on heating the air and the lightning rod itself. In addition, the station will operate only in the summer, and even then not every day.
Ball Lightning Mystery
Sometimes during a thunderstorm, an unusual fireball appears. It glows, brightly or dimly, on average, like a 100-watt lamp, has a yellowish or reddish tint, moves slowly, and often flies into rooms. The size of a ball or ellipse varies from a few centimeters to 2-3 meters, but on average it is 15-30 cm.Despite close study of this phenomenon, its nature is still not clear. During a thunderstorm, objects and people are positively charged, and the fact that ball lightning bypasses them indicates its positive charge. It is attracted to negatively charged objects and can even explode.
Ball lightning appears due to the energy of ordinary lightning, at the place of its break, bifurcation, or at the place of impact. There are two hypotheses of its physical essence: according to the first, it constantly receives energy from the outside and due to this "lives" for some time. Supporters of another hypothesis believe that lightning becomes an independent object after its occurrence and maintains its shape due to the energy received from ordinary lightning. No one has yet been able to calculate the energy of ball lightning.
note
When buying dogs, pay attention to the number and name. The sliders differ depending on the type of lightning: tractor, metal or twisted.
Helpful advice
A zipper with worn or missing teeth will need to be replaced.
Too tight or poorly closing zipper can be adjusted by pressing the slider with pliers.
