Looking at the barrage, Lin Feng smiled and said, "Some friends may have guessed, that's right, wait a while, I'm going to dig a snow hole here, when I am sheltering tonight." ”

"Snow caves, as the name suggests, are to dig a shelter in the snowdrift, it is a necessary way to survive in the cold, and it is also a kind of shelter, I remember saying before. The snow cave can help you protect you from the wind and cold, and can even be used to store food!"

"Speaking of snow caves, the Inuit who live in the Arctic Circle are a master, and this is their stunt to survive in the cold land!"

After Lin Feng finished speaking, someone in the live broadcast room said:

"Aren't they Eskimos?"

"Eskimos and Inuit are just called different, right?"

"It's different, isn't it? Master Feng, explain a wave!"

“233333”

For a while, the barrage full of screens was full of questions, and when Lin Feng saw this, he could only answer one by one: "Eskimos and Inuit are just different names, the name Eskimos were originally called by Indians, which means people who eat raw meat. ”

"They themselves don't like the appellation, but call themselves Inuit, which means 'real people'. In '06, the Inuit nation issued a statement to correct this name. So, when you met Inuit in the Arctic Circle, don't call them Eskimos, lest you be beaten up by the group. ”

"The Inuit, like us, are yellow,. In the past, they made a living by fishing and hunting in the snow, but today most of them live in Alaska, North America, and their social level is close to that of their ancestors. ”

After listening to Lin Feng's explanation, another wave of barrage hit.

"I always thought that because New Yorkers look similar to Lao Mei, they are also yellow?"

"666, the posture has risen, this one has to be written down, so as not to take the college entrance examination!"

"While watching Master Feng's live broadcast, I made a geography scroll, which is beautiful!"

Under my persuasion, our geography teacher has also become a fan of Feng Ye, and often shows us Feng Ye's videos in class!"

"I'm rubbing, so good?"

"I lack a teacher like that......"

Seeing that someone was praising himself in the barrage, Lin Feng smiled awkwardly, when I was in class, put my video, is this really good?

However, if you think about it carefully, there seems to be no problem, after all, the wilderness live broadcast I did is also a science and education program, and I still have a lot of geographical knowledge.

Immediately afterwards, Lin Feng continued: "Just now, I saw that many people asked, why can snow caves or Inuit igloos be heated?"

"The reason is actually very simple, the snow cave is a kind of artificial shelter dug out, so there will be a lot of air mixed in the snow, and the air itself is a bad conductor of heat, plus it can shelter from the wind, so the temperature inside the cave will be much higher than outside!"

"At night, the temperature outside may reach minus 50 degrees, but the temperature inside the snow cave may only be minus 10 degrees, or even close to 0 degrees!"

"It's no joke, as long as your cave is properly made and the temperature inside it can definitely give you a good night's sleep. But now, because time is running out, I can only dig a relatively simple one, as long as I can survive this blizzard. ”

As he spoke, Lin Feng had already taken off his mountaineering bag and untied his skis from it, "I didn't bring a shovel or anything, so I had to use it, this is what I said before, the importance of tools, if I threw it away in order to reduce the weight at that time, then now I can only dig snow with my hands." ”

The snow is thick and hard.

In many cases, Lin Feng needed to use Malay swords to open the way, cut them into blocks, and then dig with skis to save a lot of effort.

While digging, he explained: "There are many ways to dig a snow cave, and this one I am doing now is the easiest one. Dig a half-meter-wide passage longitudinally, and then make a bed on one side that can accommodate me. ”

"If you have all the tools, you can also try to build an igloo, which is much more comfortable than a snow cave, and I will show you this later......"

Soon, the passage was excavated, and Lin Feng used skis to make a narrow cave on his left side that could accommodate himself.

Sitting down at the passage, he explained: "The most important reason why this passage was built is that the cold air sinks. At night, it sinks to where I'm sitting, so there's another name for this passage, which is Cold Well!"

"Don't underestimate this passage, it helps keep me out of the cold air and makes my bed warmer. ”

Lin Feng took out a parachute from his backpack and spread it on the snowbed, "When I sleep, I can wrap my body in the cover of the parachute, which will be much more comfortable." ”

"By the way, when digging a snow cave, there is another thing you have to remember, the size must be appropriate, if it is too big, the heat will be dispersed, and at the same time, it must not be too small, because the snow will shrink, and you don't want to be buried alive by the snow when you sleep, right?"

After that, Lin Feng took off his gloves and smoothed the roof of the cave with his palm, "Finally, in the end, you must find a way to smooth the top of the snow cave, if you don't do this, because of the accumulation of heat, the snow on top of your head will melt, drip on you, and wet your clothes, then it will be worth the loss." ”

In a short time, a delicate snow cave was dug.

Lin Feng remotely controlled the drone and took a shot, quite satisfied with his masterpiece.

This is the first time he has dug a snow cave in the live broadcast room, so both new and old viewers feel very novel.

Before this, many people were still worried that there were no resources in this place, so how to build a shelter, but unexpectedly, Lin Feng immediately came up with a stroke of genius and easily solved this problem.

"6666, it's pretty warm to look at!"

"Science for survival. ”

“233333”

"Hibernating maple online!"

"Stop sending barrage, hurry up and take notes, this is too practical!"

"Master Feng, you made the snow cave so beautiful, do you want to hibernate in it?"

"You're really a fucking talent, and you give the anchor 1 airplane —— anchor, you're really a fucking talent!"

"Night owl 2333 gives the anchor 1 Super Rocket—— dry goods, dry goods!"

Lin Feng saw that someone was giving gifts, so he thanked him: "Thank you for the gifts, here, a snow cave is basically completed." It's going to be cold, but I'm sure it should help me get through the long cold nights. ”

"The snow cave is a great shelter for marching in the snow! Three years ago, four Dutchmen who were snowboarders came here to have fun. At that time, they also encountered a snowstorm and were stranded on a snowy mountain not far from here. Later, these people built a temporary shelter like this, and they held on to it for four days before they were finally rescued!"
