Live Wilderness Adventure

This, how does this appear?

Leonardo watched Bi Fang take out the second hand from the watch, rubbed it on his hair a few times, put the leaves on the pad and put it into the water, then pointed to the static direction and said that it was north and south.

What North and South?

what?

[I know, this is the Lorentz theorem! 】

[Speaking of Lorentz's theorem, I slowly typed a question mark]

【Is it magnetization? Didn't go to school? It should be the same as the compass, but it is temporary]

"The principle is actually very simple. It is the forming principle of the compass, but one is permanent and the other is temporary." Bi Fang picked up the leaves in the puddle, drained the water, and put the pointer on it back again. Tight dial.

"Repeatedly rub a piece of wire or a sewing needle against the silk or hair in the same direction. I wonder if you ever played with a plastic ruler and rubbed it on your hair when you were in school, and then sucked up scraps of paper. game?

In fact, it is a truth. The iron wire will be magnetic, and it can indicate the north pole when it is suspended.

It is similar to placing a magnet rod in the center of the earth, the magnetic north pole is near the geographic south pole, and the magnetic south pole is near the geographic north pole. The magnetic poles do not completely coincide with the geographic poles, and there is a magnetic declination, but it is enough to distinguish the direction.

This will not make the magnet very strong. After a period of time, you need to re-rub it to increase its magnetism.

If you have a battery with a voltage of 2 volts or more, you can magnetize the metal by using the current. You should also prepare a small piece of metal wire. It is best to cover the outer surface of the metal wire with insulation. "

[I know the one that **** up confetti, I often play, dog head.jpg]

[No, no, no, no one really hasn't played with plastic paper to **** up confetti? 】

【But what if you don't have a watch? Can't everyone bring a wire with them? 】

Leonardo also raised such doubts, indeed, what if there is no watch? Or an electronic watch?

Such an approach still has limitations.

He wanted to know a more general, more general method from Bi Fang.

"Without a watch second hand, a thin, flat razor blade can also be used to indicate directions, as it is made of two types of metals bonded together. Carefully rub the blade in the palm of your hand to make it magnetic and then suspend it. Hanging it up, you can achieve the same effect.”

"If you don't have any of these, and you are really lost and the phone can't get through, then you can take your phone apart, there will definitely be something inside, I think everyone should bring a phone? Or a flashlight, all electronic equipment It will be all right."

Leonardo wanted to ask, but Bi Fang stopped him directly: "Forget it, under what circumstances can a person be reduced to having no equipment, no plants, no sun, and even the terrain. Can't you?"

The audience will smile.

"And sewing needles or paper clips are all necessary things for outdoor adventures, don't you?"

Leonardo scratched his head: "I brought a kettle, a flashlight, a knife, water purification tablets, and a medical kit, that's all... Anything else?"

Bi Fang didn't bother to say anything. After all, the other party was only an amateur. He might have prepared these things by feeling, and if he could have water purification pills, he would have a good sense of outdoors.

"Among the basic wilderness survival tools, knives are the most commonly used tools in critical situations."

"In addition to this, a knife, waterproof matches, candles, fishing line, hooks of various sizes, two small baits, wire for traps, water purification tablets, whistle, rope, paper clips or other Sewing needles, medical tape, adhesive plaster (band-aid), dental floss (tough silk thread), compass, tweezers, paracetamol (pain reliever), antiseptic alcohol."

"Put all of these things in a small container. This container can also be used as a small pot to boil water in an emergency. Seal it and keep it dry. Make sure to put your wilderness survival kit in your own before each trip. Backpack or clothes pocket."

[Take it down and write it down, place the order here, and keep it in the bag later]

【Don't think you can use it? 】

【In case you get lost in the forest in the future, dog head.jpg】

[Others explore, fully equipped, ×, Fang Shen explores, a pair of pants, √]

This was the first time Bi Fang had told everyone in such a detailed manner what to prepare for an adventure, and he immediately wrote it down.

"Basically, I have already mentioned all the methods of identifying directions, except for very few ones that have little applicability. For example, ant nests always go north-south, and others are completely sufficient." Bi Fang did not address this issue. Too much entanglement, move on.

While walking, he said: "It's not enough to have a general direction. Many times, you may have lost your way as soon as you turn around, because the surrounding environment is too similar, so each time you go forward, you must first take the path of the road. A certain geographical feature of is a marker.”

"That is to say, you have to find a certain geographical feature on the ground, such as a tree, make this reference point in the same direction as you are heading, and walk towards it, and then repeat this process continuously until you know the destination. ."

"The ant nests are north-south?" Leonardo quickly followed, and asked incredulously.

"Yes, this is the structural intelligence of the creatures, ants and termite nests are 'mounds' or 'thin blade-like' structures, and must be oriented north-south, with the opening of the hole south, so that it can be illuminated by the sun in winter. In summer, we can avoid direct sunlight.”

Leonardo looked shocked: "You know too much!"

"You don't know anything, how can you come out and mix? When you know the function and name of each plant, the habits and weaknesses of each animal, the production and use of each tool, the cause and trend of each terrain, You won't be afraid of the wilderness anymore."

"Then have you reached such a state now?"

"Me? I'm still a long way off."

Bi Fang crossed the dense woods and stepped onto a rock, and the sound of gurgling water suddenly became louder.

A stream that was only two or three meters wide appeared in front of everyone.

Leonardo looked happy, his pale face returned to blood, and he really found it!

He couldn't wait to come to the stream, UU reading www.uukanshu. com held up a puddle of clear water. The streams here gathered from nowhere. After being filtered by rocks and sand, no impurities could be seen, and they were clear and transparent.

But with the lessons learned, Leonardo didn't dare to drink it in his mouth, he took out the kettle to fill it up with water, and put two water purification tablets in it.

[Although I have said it many times, I still have to shout, Fang Shen is awesome! 】

【Really cow! 】

Every step is very safe. If you look for a water source, you will definitely find a water source.

If you can find your way, you will find your way.

How can such a person not give people confidence?
