If we go out to the wild, fire is a very important thing. On the one hand, it can keep warm and heat food, and on the other hand, it can also protect against wild animals. There have been cases where batteries can be used to make fire, which is actually true. Another way to make fire is the flint that we see on TV. How to start a fire with batteries in the wildIn fact, battery fire is not a very difficult skill. It only requires batteries and tin foil. Batteries are easy to buy on the market, and tin foil is the silver packaging that usually wraps chewing gum. The principle of battery and gum paper fire is to let the battery short circuit and generate a lot of heat to ignite the tin foil and other ignition materials. It is natural that the positive and negative ends are hot during the operation. If you feel unsafe, you can put paper at both ends to ensure safety. However, please note that tinfoil burns quickly, so be sure to light the fire starter before the tinfoil burns out. If the ignition fails several times, it may be that your tin foil is not dry enough and the contact points of the tin foil are not cut into small strips. Doing the above two points can increase the success rate. Although this kind of fancy fire-making method is gorgeous, it is extremely harmful to the battery, because the principle of fire-making is to short-circuit the battery, so after a few short-circuits, the battery will be scrapped and lose its function. So don't use it as the main means of making fire, just use it as a backup in an emergency. What is flint?Flint is also known as flint, which is called white flint or white mara stone in some places, and later it was called "quartz stone". As long as you hold it on any hard stone or iron block, it will produce sparks whether it is hit or rubbed. The flint of a lighter is mainly an alloy of cerium and lanthanum, which is easy to burn. It is a siliceous rock, hard and dense. Primitive people in the Stone Age used flint to make fire. Today, flint is still used as a raw material for grinding. How to make fire by drilling woodFirst, find suitable dry wood as the drill board, such as soft poplar and willow. Then find relatively hard branches to drill the drill board. Then, drill a "V"-shaped groove on the edge of the drill board. Finally, place flammable cotton cloth or dry branches, leaves, pine needles, etc. under the drill board, and then use both hands to drill a hole hard until smoke and sparks appear. |
