How to make fire with a battery. How can I make fire from a finger battery. DIY electromagnet

Bonfire in field conditions often means the life of a traveller. It is simply impossible to overestimate its importance: the fire of a fire is warmth with which you can warm yourself, it is an opportunity to dry things, cook food. Sometimes fire is just an opportunity to survive. Usually we are used to kindling it with matches or a lighter, which are always at hand (many tourists take dry alcohol or some kind of liquid to kindle a fire with them on hikes). But this is not always at hand, and situations are different. And if suddenly the situation is extreme: the matches are wet, the lighter does not work, the forest around after the rain and everything around is damp? What then? Die from the cold? Or still try to make a fire? But as?

Found on the net very interesting project from Grigory Sokolov dedicated non-standard methods kindling a fire in field conditions - I share. There are many of them and fire can be obtained almost always. I made a selection of the most interesting methods from his collection, maybe it will be useful to someone.

Method number 1. An old flint lighter that ran out of gas.

The most common situation in the campaign. There was the last lighter, but here's the annoyance - all the gas came out. What to do, how to get fire? The video answers this question. Even an empty lighter can provide you with fire and warmth.

Method number 2. Obtaining fire in a damp forest by friction.

Situation: For making fire, only a knife and a small piece of rope are at hand. It has recently rained in the forest and everything around is damp and wet. Technique - we kindle a fire with the help of friction with a bow.

Method number 3. Getting fire from a battery and a small piece of foil.

Batteries in our time are such a thing that very often are at hand. Know that if you have a battery and some foil, for example from some kind of food packaging, then you also have a fire.

Method number 4. Friction method with wire

A knife and a small piece of steel wire is actually all that is needed to make fire in this way. And yes, a little exercise. 🙂

Method number 5. Method of making fire by rolling cotton wool with chalk

In places where people used to live, in old abandoned houses, you can always find cotton wool. In furniture, mattresses, upholstery. Chalk - whitewashing the walls. With this method, you can get fire.

Method number 6. Getting fire with the sun and a condom

Condom on a hike generally speaking useful thing. In addition to its direct purpose, it can be used as a hermetic bag, as a container for storing water, and below - as a means for kindling a fire in field conditions.

Method number 7. Getting fire with a spoon and the sun.

An ordinary steel spoon, which should be slightly bent, a little soot from the pot and a piece toilet paper- that's all that is needed to get the fire. Yes, and of course - sunny weather.

Method number 8. Getting fire from the sun and an old gas bottle

Old gas bottle has one very useful part for this method of making fire. Namely, the bottom. An empty beer can, by the way, will also work.

Method number 9. Fire from the sun and a reflector from a flashlight

It turns out that the reflector of a flashlight, headlight or any other device for directional light is an almost perfect lens for getting fire from the sun.

Method number 10. Fire from the sun and two bottoms of bottles

“Use what is at hand and do not look for another.” (c) Vilias Fog. In this case, the fire is produced from garbage, which is often much more around than required. The design, consisting of the bottoms of two glass bottles, not a large number water and, of course, the sun may well provide you with fire.

Method number 11. Old light bulb, water and sun.

Old light bulbs can be found in a place where people once lived. And they can serve good service when making fire, if there is nothing else at hand.

Method number 12. Ice + sun = fire!

And finally - a completely extreme technology of making fire. Ice, sun, cleaver and a little hard work. Hardly useful, but very impressive!

Grigory Sokolov - thanks a lot for the material provided.

British traveler and writer Bear Grylls often teaches others how to survive in difficult and wild environment. He tells how to navigate the terrain, build a lodging for the night, find food and so on. Now the man showed how to make a fire with three simple items that are most likely to be with you on a hike: this is chewing gum, cotton wool or fluff and a regular battery.

The Bear Grylls program "Survive at all costs" is known all over the world, and many celebrities took part in it,. The other day, he came to the British morning show This Morning (“This Morning”), where he showed the hosts that you can easily start a fire with the help of improvised means - a package of chewing gum, cotton wool or fluff and a battery.

The heart of survival is ingenuity.- Bear Grylls, traveler and writer

So, to start a fire, you need to remove the foil from a pack of chewing gum and cut off (tear off) a thin strip with a narrower center.

Then each end of the foil must be attached to the bases of the battery - this way current will begin to pass through it and it will heat up. And due to the fact that the middle of the foil is thinner, it heat may ignite dry material.

And then just bring the foil to a piece of cotton wool or fluff that you have. It will burn!

Instead of cotton wool, you can take wood chips, dry grass, fluff that collects in the navel - everything that is at hand.

Some viewers were a little disappointed, believing that such a set of items might not be at hand at the right time.

How to get the most out of a battery? How to make fire without matches and a lighter? How to "bury" the battery correctly? It is difficult for a civilized person to imagine life without batteries. But, as experience shows, we are not sufficiently informed about the possibilities of things that surround our life. 10 life hacks with batteries are proof of this.

1. Mobile hand warmer

• People are divided into two types. Some even feel comfortable in the cold. Others freeze in mid-July. If the problem of cold hands is familiar to you firsthand, keep on hand, or rather in your hands, a mini battery heater. Wrap the battery with foil, securing it to the contact poles. Clamp the poles and enjoy the warmth. Before taking the mini heaters with you, make sure that the batteries are charged.

2. Charged or dead - how to find out?

• But how do you know if the battery is charged without devices? Drop the battery on the table with the minus side from a small height (2-3 cm). Discharged loudly rebound and fall. A charged one will most likely land on the pole with a thud.

3. Do-it-yourself electromagnet

• With the help of simple items - a battery, insulated copper wire (at least 1.5 meters) and a large nail / bolt, you can make a powerful electromagnet. Wind the wire around the nail from one end to the other. Each end of the nail should have "tails" to connect to the battery. As soon as you attach the ends of the wire to the battery, the design will turn into an electromagnet. Search or select any metal objects. After disconnecting the elements, the electromagnet loses its power.

4 Battery Fire: Prison Lighter

• One of the favorite tricks of life hackers (and not only) is making fire with a battery. You will need a strip of foil with a paper base (for example, from chewing gum) 6-7 mm wide at the ends with a narrowing of up to 2 mm in the center. Attach the ends of the strip to the poles of the battery and bring the device to the paper, which will immediately ignite.

5. AAA instead of AA

• Need AA, but only AAA is at hand? The problem is solved simply - with a piece of foil that will hold the battery in the slot and bring the device into working condition.

6. Opening the Krona battery

• Alkaline batteries "Krona" contain 6 AAAA batteries with a voltage of 1.5 V, which are easily converted into AAA batteries using the above life hack.

7. Why wrinkle dead batteries?

• A penny saves a ruble. Do not throw away exhausted batteries. If a discharged battery is crushed, for example, with teeth or pliers, it will gain momentum for a second life. By the way, very crumpled battery may leak and damage the device.

8. Smartphone stylus

• Incidentally, the downside AA battery can be a stylus for capacitive touch screen.

9. A gift to future generations

• A battery thrown into the trash will cause serious damage to nature. Once outside, it will pollute with harmful components 20 square meters land or 400 liters of water. Put used batteries in plastic bottle, but while it is filling up - find the nearest collection point for batteries, which, alas, are few in Russia.

10. Responsibility to nature with Ikea

The Ikea chain of stores has resumed accepting used batteries and mercury-containing lamps. The store does not charge any fees for the collection and subsequent disposal of batteries. Look for special containers at the exit of the store!

You can light a fire with a battery and foil due to the fact that when leaking electric current heating through the metal. This heating is stronger, the more powerful the battery and the smaller the cross-sectional area of ​​the conductor. In the case of foil smallest area will be in its narrowest section, it is there that the heating will be sufficient to ignite the paper or other tinder attached to the foil.

Getting fire with a battery and foil

The method is based on the same principle using a simple finger battery, stranded wire and matches (used when the box gets wet or to create alarms using pyrotechnics). In this case, the narrowed section is created by removing all the strands of the wire except for one. This core is wound around the match head and, heating up during the closing of contacts, sets fire to the match.

In order to start a fire with foil and a battery, you need to take a chewing gum or chocolate wrapper (although almost any other foil, for example, food foil, will work for this purpose). In survival conditions, foil can be found among the garbage, including even on the coast of a desert island, where the foil can be washed by a wave.

Paper-backed foil is best for making fire, as the paper then acts as a tinder pressed tightly against the metal layer and ignites when the circuit is closed. But also the usual clean aluminium foil will work, although it will take more work.

1. From the foil, it is necessary to cut a strip of such a length that its edges freely reach the poles of the battery. The width of this strip must be at least 5 mm. If the strip is thin enough, the entire foil will become noticeably hot and could burn your fingers.
2. A narrowed section about 2 mm wide is made in the center of the strip. If this section is made too wide, the foil may not heat up to the desired state, and if it is too narrow, the foil may tear. The transition from wide to narrow should be smooth. For convenience, the foil is folded in half and cut off the excess.
3. If the foil is without a paper layer, it is necessary to use tinder, for example, dry fluff from cattail. Two small balls are rolled from the fluff, between which a thin piece of foil is clamped.
4. With the index and thumb, both ends of the foil strip are pressed against the opposite terminals of any battery - the circuit closes, and the paper on the foil ignites, however, only for a moment. At this moment, she needs to have time to set fire to tinder or kindling, unless, of course, these manipulations were conceived for making a fire.

The video shows how to start a fire with a battery and foil:

In the case of clean foil and tinder, a slightly different picture is observed when the battery contacts are closed. Here the tinder begins not to flare up, but to smolder. Therefore, in order to kindle a fire, it must be inflated, providing an influx fresh air, and put in kindling.

If the foil strip turned out to be too short and does not reach the battery terminals, or for the convenience of working with the battery itself, you can do the following. The side of the battery case from the side of the negative terminal is cleaned of glue and film. This stripped part has a positive charge, therefore, one of the ends of the foil strip can be applied to this area.

When lighting a fire from a battery mobile phone or a smartphone, there is no need to make the foil tape so narrow in the central part: a width of 5-8 mm will be enough. The edges of the tape are folded into a "sausage" for better contact with the battery terminals. Also in this case, it is better to protect the fingers by placing some kind of heat insulator between them and the foil, for example, paper folded in several layers.

On a note

Some people think that you can start a fire with a battery and chewing gum, but this is not so. To light a fire, you will need not the chewing gum itself, but a foil wrapper from it, preferably with a paper layer. It is this foil, together with any battery, that will allow you to get a flame.

Batteries suitable for starting a fire

Only charged batteries and accumulators can be used to make fire: discharged, for obvious reasons, the foil will not be able to heat up, since they will not ensure the flow of current through the foil.

In extreme cases, a fire can be started by breaking through the case of a lithium-ion battery. But this is dangerous: often with mechanical damage, such batteries swell, catch fire and, due to the large amount of gases released, can explode and fly off several meters to the side. This is fraught with burns and fires.

Extinguishing lithium-ion batteries ineffective, since they can often burn without access to air, and water that has got on the element can lead to the release of hydrogen, a flammable gas

Burning lithium ion battery

It is important to remember that many phone batteries are protected against short circuits. Therefore, when planning to kindle a fire from such a battery, you need to use foil maximum length. To do this, you can cut a strip from a regular wrapper, for example, with a spiral.

It is worth noting that in the conditions of survival, before making a fire with the help of batteries, you need to carefully consider everything. So a telephone, a walkie-talkie, a navigator or a flashlight working on them, may in a certain situation be more important than a fire, for which you can plant a single source of electrical power.

However, the video below shows that starting a fire on your phone's battery consumes approximately 3% of your battery life:

From my own observations, I can say that not always attempts to breed, add fire in this way end in success. Sometimes the paper in the thin part of the foil is simply charred and torn without catching fire, and sometimes there is not enough residual battery charge to heat the foil to the desired temperature.

A case where a too narrow jumper was made on a strip of foil.

Security measures

When using this method of making a fire, the simplest safety measures should be observed:

• Light the fire away from flammable substances (such as gasoline, alcohol and dry vegetation).
• When closing the contacts with foil to protect your fingers from burns, you can use paper folded several times.
• Batteries must not be disposed of in a fire - a battery in a fire can explode, which is fraught with eye injury, burns and fire.
• Used batteries must be taken to special collection points, as their disposal with household waste leads to contamination hazardous substances soil and ground water. These substances subsequently enter the human body with water and food, causing various diseases.

The last rule also applies to tourists: while most of the garbage can be disposed of by burning and then buried in the ground, all used batteries must be taken with you to " big land". It is unlikely that a couple of spent batteries will make the backpack noticeably heavier, but left to rot in nature they will cause significant damage. environment and in the future - to the person himself.

Despite the popularity of this method of starting a fire, in my opinion, it is more suitable for an urban environment, where the battery charge in the phone may play a smaller role than, for example, a person’s desire to light a cigarette for lack of other sources of fire. Nevertheless, like other knowledge, this method has value, since anything can happen in conditions of survival, and the ability to make fire is one of the main ones for maintaining life.

Naturally, the first thing that comes to mind is a magnifying glass, or just curved glass, or even a polished spoon - in general, in the presence of the sun, you can make fire using almost any reflective surface. What if it happens at night? And if it is cloudy, as often happens in the dense taiga forests? If the sun can't break through at all spruce paws? So, it's worth rummaging through your pockets!

Easier nowhere

Let's say you find an ordinary AA battery in one pocket. Suitable and AA, and AAA, and a small "barrel" C, and a thick D - it does not matter. Half the battle is already done, now you need to find a piece of chewing gum in another pocket. Or a pack of cigarettes. Or, at worst, a chocolate bar - in general, any item that has foil in its packaging. Ideally, you need a two-layer material, where the foil serves top layer, and the bottom layer is paper. But clean foil will work too, it just takes a little fiddling with it.

You will also need a knife, but if necessary, the foil can be carefully torn without using sharp blade. So, first, cut a fairly wide strip from the foil (about 1.5 cm wide).

The length should be such that one end of the strip can touch the positive end of the battery, and the other end can touch the negative end. Now you need to make the central part of the strip thin, that is, create a narrow jumper there (about 2 mm wide). That's almost all.

Find flat surface, put something that quickly ignites on it (for example, dry moss, if you are in the forest), and “stick around” the jumper on the foil with this material. In our experience, we wrapped the wick of an ordinary candle in cotton wool.

If we now connect the ends of the strip with the poles of the battery, then a current will flow through the strip, it will begin to heat up, and the paper layer will light up.

It burns out in a matter of seconds, so it is necessary that the strip touches the flammable material and it has time to grab.

If you only have regular foil, the method will work too, but you will have to wait longer - until the heated foil ignites the moss or cotton wool directly.

Electrical cases

The secret of focus is very simple. When connecting the poles of the battery, a short circuit occurs; a multiplied current flows through the metal foil (circuit), from which the conductor heats up. In the narrowest place, that is, on a two-millimeter jumper, there is enough heat to heat the metal and set fire to the paper layer.

Doing this experiment at home, you should upper part gently “fluff” the cotton wool that the foil touches for better ignition. Caution: the poles of the battery become hot during the experiment - you can burn yourself. In general, batteries are not a toy for children!
