Desert Island Survival Belt System

Chapter 356

Slowly cut the bottle of liquid nitrogen with a knife!

The aluminum bottle is vulnerable to a sharp knife, and white smoke is spraying out from the hole in the bottle mouth. These things are very cold, after all, it is a gas at minus [-] degrees.

Quickly pour liquid nitrogen into the bamboo tube, you can clearly see the smoky liquid, then put the sealed bottle filled with water into the bamboo tube, and then seal the bamboo tube mouth with leaves.

"Liquid nitrogen is so powerful!" Han Xuening was exposed to liquid nitrogen for the first time. She was blocking the bamboo tube with leaves, and she could clearly feel that the bamboo tube was cooling down rapidly.

It took only ten seconds from the injection of liquid nitrogen into the bamboo tube, and some water droplets appeared on the outside of the bamboo tube, and these water droplets turned into white ice beads in the next second!
10 seconds passed!
Everyone is looking forward to the water in the bamboo tube!
Has it all condensed into ice?

After all, this is liquid nitrogen, a liquid at minus 200 degrees!

Do you want to open it and have a look?

In case...the water in it is not condensed now, and within a few seconds of opening and observing, the liquid nitrogen will evaporate a lot.

However, if all the water inside has condensed and you are still waiting like this, will something happen to the ice water due to the continued low temperature.

For example, the ice bottle broke, or exploded?

Qin Fengyi asked, "Do you want to open it to see if the water inside has turned into ice?"

"Not enough time?" Lin Qingxue thought for a while and said, "Should we wait? Liquid nitrogen will evaporate quickly when it meets air."

"Okay... I'm afraid that something will happen if the time is too long." Qin Fengyi sighed, liquid nitrogen is hard to come by, so it has to be used sparingly.

"There should be no accidents!" Han Xuening acted as a teacher and explained, "Everyone knows the boiling point and freezing point of water, and the high temperature generated by fire when burning is at least hundreds of degrees, or even thousands of degrees. Under normal circumstances, the temperature of the water will not exceed 100 degrees, because this has reached the high temperature range of water temperature."

Han Xuening looked at Qin Fengyi, who was listening carefully, with a smile on her face, "The lowest temperature of water is the freezing point, and it will not decrease with liquid nitrogen. Once it reaches the freezing point, it will only condense into ice, and the temperature will naturally not drop. How many."

"Hmm..." Qin Fengyi thought carefully, and felt that what Teacher Han said was right, so he asked, "After the water boils, it is 100 degrees. What is the lowest temperature when it is approaching the freezing point?"

Lin Qingxue was equally curious. Although she is a top student, there are simple things in this world that a top student doesn't understand.

"This..." Han Xuening said bitterly, "Of course I don't know the author's junior high school diploma, and I didn't check the information...so..."

"Understood..." Qin Fengyi complained, "The author is too lazy, so lazy even without education, no wonder he keeps rushing to the street."

"Is it really okay for you to complain about the author like this?" Lin Qingxue pursed her lips and squinted at the two of them.

Another ten seconds passed...

Qin Fengyi and Han Xuening can't wait any longer. Driven by curiosity, you really want to know whether the water in the bamboo tube has turned into ice or not. The passage of time will be greatly slowed down. Although it is only 1 minute, there is a century so long.

"Let's... Let's open it and have a look!" Han Xuening couldn't bear it anymore, "The temperature of liquid nitrogen is minus 200 degrees. After such a long time, it should be frozen."

"I agree too!"

Qin Fengyi quickly opened the bamboo tube, immediately took out the bottle, and then put another bottle in to seal the bamboo tube. This action only took a few seconds, which can be described as very swift.

But in just a few seconds, the liquid nitrogen evaporated a lot, and everyone who watched felt distressed.

"Damn it, it's so cold!" Lin Qingxue held the bottle taken out of the liquid nitrogen. There was still cold air coming from the bottom of the bottle, and the cold air was all the liquid nitrogen stuck to the bottle.

After the liquid nitrogen comes into contact with the air, it will evaporate in a short time. In just a few seconds, the thick mist becomes extremely thin, and only a little curl of cold air rises.

"It's frozen!" Han Xuening looked at the transparent plastic bottle, half of which was frozen, and the other half was still water.

"Everything soaked in liquid nitrogen has condensed into ice, and the top of the bottle is still water. It seems that the bottle needs to be turned upside down and stuffy for a while." Qin Fengyi stared at the bottle just taken out of the liquid nitrogen bamboo tube. Chunks are floating in the upper end of the bottle.

"Okay, let's hurry up!"

Han Xuening quickly opened the sealed bamboo tube, then quickly took out the bottle inside, turned around and stuffed it in again.

Ten minutes later...

Dozens of frozen ice bottles are lying in the special refrigerator, because the liquid nitrogen is lost behind, and there are more than a dozen bottles of water that have not completely turned into ice.

"These half-water half-ice... put them in the refrigerator directly. Anyway, there are a lot of ice bottles in it, and I guess they will all be frozen into ice in a short time." Lin Qingxue made ice water for a long time, only feeling cold all over, especially Those little hands.

"Stayed in the ice cellar for a long time...it's quite cold." Han Xuening was rubbing her red hands while exhaling heat.

"Come on, let me help you!" Qin Fengyi lovingly grasped Han Xuening's little hand, and was breathing hot air.

"Damn!" Lin Qingxue pouted her lips dumbfounded, and Xiao Nizi pointed weakly at the 40-degree heat outside, "It's fine if we go out to warm up for a while, as for showing affection here?"

Xiao Nizi doesn't dare to act like a spoiled child to Qin Fengyi now, she can feel that this guy's animal desire can't be restrained anymore, now Han Xuening's aunt is here, and right now, Lin Qingxue is the main output target.

Afterwards, Qin Fengyi made a few more bamboo cages. The whole is a box, like a nesting doll. The outside of the bamboo box is covered with several layers of banana leaves. This kind of leaves are huge and wide, and the airtightness is very good.

Lin Qingxue and Han Xuening are not idle either, they have been looking forward to ice cream for a long time, and they are making ice cream of various flavors.

There are many materials in the shelter, which were preserved some time ago. During the period, there are coconut sugar, finely sifted powder, and fried walnut particles and ripe mulberries.

"Mr. Han, you are in trouble. Do you dare to eat something cold?" Lin Qingxue was stewing coconut milk in an iron pot, trying to make it as thick as possible, so that it tasted good, and it might have the texture of a small pudding.

"It should be fine!" Han Xuening rarely showed the appearance of a little girl, holding her delicate face and smiling cutely, "Eat a little, it should be fine!"

"Okay... I can't wait to eat ice cream now!" Lin Qingxue stirred the viscous coconut milk in the pot. Put the bamboo tube into the cold water in the bucket and wait slowly for it to cool down.

Han Xuening squeezed the red flesh of the watermelon with a mosquito net to squeeze out the juice inside.

Brother Pingtou found an opportunity and was waiting to eat the juiced pulp.

"Scarface, wait until I take out the watermelon seeds before you eat them!"

　I haven't written for a long time, I haven't saved any manuscripts, and I'm under a lot of pressure to code now. Recently, after work, I take subject two to practice driving. After school, I go home and eat at 8 o'clock. I have to tell my daughter a bedtime story, so I don't have much time to code.

　　At most one week, it will resume 2-4 updates, please don't abandon it
