What can be used to make a fire?
This is the most well-known but also the most difficult method.
First of all, find the right wood drilling board, dried poplar, willow and so on. Will be a good choice, because their texture is soft. Then find a suitable branch as a drill bit, which is hard and the conditions are not as harsh as the drilling board. Then, drill an inverted V-shaped groove on the edge of the drilling plate. Finally, put a flammable tinder or dead leaves under the drilling board, and then drill hard with both hands until a fire comes out.
The second method: strike a stone to make a fire.
Find a hard stone to make a "flint" and knock it down with the back of a knife or a small piece of steel to let the spark fall on the fire. A hacksaw with teeth on the blade can produce more sparks than an ordinary knife. When the fire starts to smoke, blow or fan it slowly to ignite the open flame. Of course, not all stones can ignite the fire, and the sparks from the stones must have a certain amount of heat and duration to ignite the fire.
The third type: battery fire method
If there is a big battery, connect the positive and negative poles at both ends of the peeled pencil lead, and in an instant, pencil lead will burn as red as electric furnace wire.
If you travel by car, you can take two long wires and connect them to the positive and negative poles of the battery respectively. If there is no wire, you can use two wrenches or other metal tools instead. If the lead is not long enough, you can take the battery out of the car. Touch the ends of two wires slowly, and the short circuit will produce sparks. At this time, a piece of cloth soaked in gasoline is the best kindling.
The fourth type: bow fire drill.
Tie shoelaces, ropes or belts with tough branches or bamboo pieces to make bows. Wrap a dry stick around the bow and use it to spin quickly on a small piece of hardwood. This will drill out black powder, and finally, these powders will smoke and generate sparks to ignite the fire.
Fifth: convex mirror ignition method
Any convex mirror (such as a telescope) with a diameter of more than two inches can be used to gather sunlight in bright sunlight and make it shine on the prepared kindling, thus igniting the kindling. It is well known that a magnifying glass (convex lens) is used to focus flammable kindling (rotten wood, yarn drawn from cloth, dried bark torn into thin slices, dried sawdust, etc.). ) to make a fire. The quickest way to ignite with a magnifying glass is to irradiate the propellant or fuse of gasoline, alcohol and bullets, and the fire can be ignited in 1 ~ 2 seconds. In addition, the magnifying glass can also ignite wet or soaked matches in water to dry through sunlight. Magnifier is an important ignition tool.
If you don't have a ready-made magnifying glass, you can take a convex lens from the telescope, sight and camera instead. There was an example: 100 years ago, a foreign expedition suddenly broke down in the frozen Antarctic. One of the expedition members processed a crystal-clear ice cube into a round extra-large convex lens with a thick center and a thin periphery, and then stood up the ice convex lens and focused it in the sun. Finally, ignite the fire and get the fire. Put the fire on the focus of the flashlight reflective bowl, or take fire from the sun.
The sixth kind: fire vine.
Find a dry trunk, split one end, spread the crack, plug in the fire, put a cane about two feet long after the fire, step on the trunk with your foot, and quickly twitch the cane left and right to make it friction and heat, thus igniting the fire.
Seventh: simple plane fire method
Dig a long slot in the cork board, put flammable and combustible materials in front of the slot, and push it forward with hardwood strips until Mars ignites the combustible materials.
