Desert Island Survival Belt System

Chapter 355 384, Liquid Nitrogen Makes Ice
In the shelter!
Han Xuening and Lin Qingxue are preparing some bamboo tubes!
The bamboo in the bamboo forest grows very luxuriantly, which is all due to the subtropical rainforest climate.

The thickest part of the bamboo is at the bottom, where the thick bamboo joints are about as big as the mouth of a bowl.

Its inner diameter can fully accommodate a mineral water bottle, but the height of a single bamboo section cannot accommodate a mineral water bottle. After all, the height of a bottle exceeds 20 cm.

"Mr. Han, if we cut off the single-sectioned bamboo, we definitely won't be able to hold a mineral water bottle." Lin Qingxue was gesturing with a bottle of mineral water filled with fresh water.

Put the mineral water on the bamboo lying on the ground and measure it, and found that the mineral water is obviously 5 finger lengths higher than the bamboo joint!

"Let's do this!" Han Xuening looked at the bamboo on the ground for a while, "Let's just cut off the thickest two-section bamboo, and then use a machete to dig through the internal barriers of the bamboo joints."

"This way... it should be possible!" Lin Qingxue blinked her big watery eyes and thought for a while, thinking it would work!

Afterwards, the two girls were making the thickest bamboo tubes, and within a few minutes they made two bamboo tubes that could hold a mineral water bottle.

And at this time, Li Zijun also came back!
"How's the refrigerator doing?" Lin Qingxue was showing Qin Fengyi the bamboo tube she made.

"The refrigerator has been completed, but the mud is still a little damp, but this does not affect the use of the refrigerator." Qin Fengyi explained, "If dozens of bottles of frozen water are put into a humid refrigerator, the sub-freezing temperature will make the wet soil It is completely frozen, it can play a thermal insulation effect, and it is also very strong.”

"Well, just like in the Romance of the Three Kingdoms, the winter war lacks a defensive fortress, so it is like mixing sand with water and using the effect of ice to accumulate to create a city wall of ice." Han Xuening thought for a while, nodded and said.

"Yes, that's probably the reason!" Looking at the fair-skinned, beautiful and charming teacher, Qin Fengyi was a little uneasy, but it's a pity that Teacher Han came to be his aunt, and let her go for now. As for Lin Qingxue, you can make troubles as you like.

"Damn!" Lin Qingxue was thinking about the problem at first, but after looking at Li Zijun, she suddenly lost her composure, "Can you stop looking at me with such disgusting eyes, I'm afraid..."

"What are you afraid of? Can I still eat you?" Qin Fengyi rolled his eyes helplessly. Xiao Nizi has become very timid since she was slapped by him.

She used to like to quarrel with Qin Fengyi the most, but now as long as the big animal is tougher, Lin Qingxue will be cowardly.

"I'm afraid you'll eat me..." Lin Qingxue whispered.

"Okay, let's hurry up and make ice!" Han Xuening said, "Qin Fengyi, do you have any good ideas?"

"If there is a good way..." Qin Fengyi thought carefully, and frowned, "I don't know how the liquid nitrogen freezes the ice, but it can evaporate quickly, right?"

"Yes, after all, the temperature is too low, hundreds of degrees below zero. It is said that if you put a fish in liquid nitrogen, it will be frozen into an ice sculpture in just a few seconds. It is really amazing that it is still alive after thawing." Lin Qingxue compared I like to watch some weird little videos, and I have watched a lot of videos about liquid nitrogen.

Everyone is going to start making ice, most of the bottles in the shelter need to be filled with fresh water, a few bottles of liquid nitrogen and two bamboo tubes are all brought.

"Gudu... gudu..."

Lin Qingxue and Han Xuening were filling the river with relatively clear water. There were probably dozens of bottles with caps. After these flats were sealed, they could be used to make ice bottles.

"Hooho..."

Yayale is soaking his body in water in the downstream river. The wild boar crocodile can live on land and in water. While washing, it is also protecting the two mistresses.

The deserted island is becoming more and more unusual, and too many unimaginable creatures are gradually surfacing.

"Mr. Han..." Lin Qingxue looked at Qin Fengyi who was working worriedly, "I'm really worried now, I don't know what Qin Fengyi saw on that weird building."

"The inverted triangle?" Han Xuening was caressing Scarface's neck with one hand. The hair on this guy's neck was as rough as a steel brush.

"Woooo..." Honey Badger became very nervous when he heard the inverted triangle. This guy once followed Qin Fengyi to that terrifying place.

"Hey!" Lin Qingxue sighed heavily, lowered her spiritual eyes, and was gently teasing Brother Pingtou's chin with her slender fingers, she murmured softly, "That guy... he can handle everything by himself, once he meets him Whenever something happens, he will always keep it a secret."

"Maybe... this is Qin Fengyi's habit of protecting us!" Han Xuening drew circles on the ground with a twig, "After making the ice, I think I have to communicate with Qin Fengyi."

"Yeah!" Lin Qingxue nodded noncommittally, "He's a little too tired for doing everything by himself."

"Maybe I found something terrible..." Han Xuening narrowed her eyes, recalling Qin Fengyi's expression at that time.

Several people all came to the underground secret room, walked down the stairs, and could clearly feel that there were two different temperature dividing lines.

It is warm above the waist, and cold below the waist, with a temperature difference of at least 6-10 degrees.

"It's so strange in here!" Lin Qingxue blinked, squatted down and was stroking her cold ankles with her small hands, "The low place is cool, is it the reason why the cold air descends?"

"That's right, this kind of terrain is similar to a cave, and it's well sealed, which is conducive to the preservation of ice." Qin Fengyi came to the refrigerator and looked at the refrigerator he had worked so hard to make. The interior was full of woven straw mats and the like. , These things can play a role in heat preservation.

"The refrigerator looks very good, but I don't know how well it keeps the heat." Han Xuening admired Qin Fengyi very much, this guy's hands-on ability is very strong.

"Actually, we can add a few more layers of protection to the outside of the refrigerator, so that it can also keep warm." Lin Qingxue remembered the bamboo cage made by Qin Fengyi, "We can use bamboo to make a protective cover, which is similar to bamboo, and cover the outer circle with leaves Just try not to let him breathe."

"The idea is quite good!" Qin Fengyi thought for a while, "The method is feasible, and I will make a cover later, but at present we have to see if liquid nitrogen can be used."

The liquid nitrogen is probably stored in an aluminum bottle. I don't know if this thing has evaporated. After all, liquid nitrogen will evaporate in a short time when it encounters air.

If the liquid nitrogen is gone, you can only use saltpeter powder to make ice cubes, but the efficiency of this thing is definitely not as good as liquid nitrogen hundreds of degrees below zero. freezing point.

Slowly open the bottle of liquid nitrogen with a knife!

　I’m back, my mentality has improved, this book will not be a eunuch, it will continue to be serialized, I’m sorry, my dear readers, the irresponsible author will stop updating for 15 days...

　　I will not do it again
