Chapter 67 Boys have low requirements for bath water temperature anyway

Su Meng found a wooden stick about 1 meter long with a thick wrist, pulled out a piece of red-hot charcoal from the campfire with wooden clips, and put it on one end of the stick.

After a while, the wooden stick in her hand gradually formed a small concave hole with the high temperature of the charcoal, and a wisp of light smoke also came out from it.

Seeing this, Su Meng calmly poured the small piece of charcoal in the hollow of the stick back into the bonfire, then picked up a piece of bamboo and stretched it into the hollow to scrape out the carbonized parts inside. The hollow at the top of the stick deepened again.

Repeat this until the hollow of the stick is as long as an index finger.

"The next thing is to prepare the fuel." Su Meng mixed a certain proportion of pine resin and wood chips and kept stirring, while carefully teaching Du Jiayue who was watching.

She certainly can't do all these things by herself in the future. She doesn't have superpowers, and she can't take care of all aspects.

So whether it is Su Xiang, Zhang Lin, Bai Jing, Du Jiayue, they all need to support themselves.

After mixing the pine resin and wood chips evenly, Su Meng began to fill the mixed fuel into the hollow of the wooden stick, and pressed it tightly, so that the torch could burn for a longer time.

"Here, the torch is ready now." Su Meng held the torch and stretched it into the fire, and lit the torch easily.

"It's really possible!" Du Jiayue was eager to try: "It's quite bright, so can I make candles according to this method?"

Su Meng smiled, and walked out of the wooden shed holding a torch: "Yes, just find a thicker wood, and a shorter one will do."

The night on the island is extremely cold, as if it has entered early winter from midsummer.

Leaving the warm hut, the five of them shuddered in unison, and couldn't help speeding up their pace to the kiln.

The five earthen kilns are next to each other, and the heat emitted makes the surrounding area much warmer.

Su Meng picked up a few clay slabs above the clay kiln with a wooden stick, and found that her hands were still a little hot, and they were already a little half-pottered.

Then she removed the stones blocking the fire mouth of the clay kiln, and suddenly a gust of hot air rushed to their faces, making the five of them feel a burst of burning warmth.

"Zhang Lin, Bo Jing, you two are responsible for pulling the charcoal in the kiln's burner. It can save a little bit, and in this way, the temperature in the earthen kiln can be dropped quickly."

It has to be said that Su Meng is a beautiful girl who is extremely good at living, and she will never allow herself to waste any resources.

With so much firewood and burning it for so long, no matter how you do it, you can pull out some usable charcoal.

And those ashes should be kept, you must know that plant ash is a good thing.

It can be used as a good fertilizer for base fertilizer, seed fertilizer and top dressing, as well as for disinfection, killing viruses, inhibiting pests and diseases, hemostasis, storage and preservation, drying, and even used as medicine. positive effect.

These uses are what she values.

Zhang Lin and Bo Jing obediently held the engineer shovel to pull the fire port of the clay kiln. As the charcoal and ashes were shoveled out, the heat radiated even more, making their skins feel hot.

"Let's go, go dig another earthen kiln, and let this earthen kiln calm down again." Su Meng stuck a torch on the ground to illuminate the two of them, then held the torch and walked towards the next earthen kiln with a smile.

Du Jiayue was still preoccupied with taking a bath, and she kept thinking about going to sleep with the smell of sweat in her head, so she seemed a little absent-minded.

"Don't worry, if the small water tank is fired successfully, then we can take a hot bath tonight." Su Meng seemed to know what Du Jiayue was thinking, she glanced at Du Jiayue angrily, Showing a mysterious smile.

"Then if the firing fails—" Du Jiayue's face collapsed, but before she finished speaking, she saw Su Meng smiling at her maliciously, so she quickly swallowed the rest of the sentence.

"Tell me bah bah bah, if the firing fails, then at most I can only wipe my body with hot water tonight."

"Bah bah bah!"

Du Jiayue's face turned pale, and she quickly poohed three times on the ground, and finally stomped her feet.

Su Xiang: I was very speechless.

"By the way, is there any relationship between a small water tank and taking a hot bath? Is it necessary to put the small water tank on the fire, and people sit in it and perform a pot to stew themselves? But this is too time-consuming, and it is also difficult It's very inconvenient." Su Xiang somehow remembered the emoji "Iron Pot Stewed Goose" and couldn't help laughing.

The heat conduction effect of clay pots is actually not very ideal. Even if it is burned for a long time, the water in the pots will only boil slightly, and how to carry the hot pots from the fire is also a big problem.

Not to mention the pottery tanks that are bigger than pots.

"Of course not, and I'm not stupid." Su Meng hooked the corners of her mouth, as if I wouldn't tell you, seeing Su Xiang and Du Jiayue were so angry that their teeth were itching, and the other was so angry that they wanted to rush up and hug them. Holding Su Meng's arm was a burst of coquetry and cuteness.

The audience in the live broadcast room were also aroused with curiosity, and the bullet screens flew up.

"Ah, ah, don't be tricky, talk, talk, talk"

"It's not easy, just let it heat up and go down quickly (funny)"

"It's not enough to make a pot cover"

"What's the use of discussing this? It's not certain whether pottery can be made."

"If you don't understand, just ask, why does the bath water boil? If you take a bath with boiling water, you will be scalded."

"By the way, have the other groups not taken a bath for six or seven days?"

"The sour smell on the goose, goose, goose goose, is afraid that the beast can be killed directly."

"I just want to know who joined the Su Meng group, I feel like following her is going on vacation"

"I saw that not everyone can choose the place of birth, and no one chooses the place of birth near Su Mengzu"

"Shocked, Su Meng doesn't hug her thighs, what do you think?"

"Upstairs, I'll give you an analysis. There seem to be a lot of resources near the Sumeng group, but the risk factor is too high. There are bears, wolves, wild boars, and big cats. Who would dare to go there? If you go, if you are lucky, you will take a day trip, if you are unlucky, you will have extra meals for the beast, understand?"

"Hiss—it makes sense, I'm actually powerless to refute it"

"..."

Seeing Su Xiang and Du Jiayue with disconcerted faces and muffled digging of charcoal and ashes, Su Meng sighed, but was still defeated.

She walked up to the two of them and said in a volume that only the three of them could hear: "The method is very simple, it's just like this."

Su Xiang and Du Jiayue suddenly realized: "Isn't this too simple?!"

Su Meng spread her hands: "Yes, you can think of it after a little more physical knowledge, but there is a prerequisite, that is, we must have that small water tank."

"Understood, as long as there is a container, everything is easy to talk about." Su Xiang nodded thoughtfully. It seems that he will make good use of the knowledge he has learned in the future.

Xueba will never admit defeat!

The audience in the live broadcast room were all dumbfounded, and they all started typing to vent their disbelief.

"No? The live broadcast is still whispering, who is this looking down on?"

"That's right, it's fine if you don't show us when you take a shower, but now you don't even let us listen to you"

"Is there anything that our VIPs can't listen to"

"It's too much, it's just protecting us"

"Director! Where's the director! Fly the drone over there to eavesdrop!"

"Simple? Physics? Wait, why do I have a sense of familiarity? Don't panic, let me look through my physics book, maybe I can find the answer in it"

"..."

"Mengmeng, do you know how to make handmade soap? I don't think it can be cleaned with charcoal alone." Du Jiayue looked adoringly, blinking her big eyes at Su Meng, her eyes full of expectation.

"It's possible, but we don't have the corresponding materials." Su Meng thought about it seriously. As far as she knew, ancient soaps were made from animal fats, but now they don't even have oil for cooking, let alone luxury Fat is used to make soap.

Seeing Du Jiayue's disappointed expression, Su Meng paused for a moment, and then said, "I'll make some soap right away when I hunt wild boars."

Hearing this, Du Jiayue's eyes lit up again, and a smile couldn't be concealed on her face.

After the charcoal and ashes in the five earthen kilns were almost dug out, and after waiting for another half an hour, Su Meng went out again holding a torch: "Let's go, go and see if the pottery has been fired."

"Okay!" Su Xiang, Zhang Lin, Bai Jing, and Du Jiayue, who were already a little sleepy, suddenly cheered up, and got up and followed behind with torches.

As soon as he walked out of the wooden shed, a gust of mountain wind happened to blow, and the torch swayed with the wind, but it did not go out.

Su Meng shivered, and couldn't help but gasped, the temperature got lower as the night got darker.

Afraid of catching a cold, Su Meng didn't dare to delay, and hurried to the kiln, and looked at the pottery in the kiln by the light of the torch.

She took a look and found that it was impossible to tell whether the firing was successful with the naked eye, so she handed the torch in her hand to Du Jiayue, put her hand into the kiln, and touched the small water tank tentatively. He took out the small water tank.

"Come here and take a picture." Su Meng motioned Du Jiayue to bring the torch closer so that she could use the brightness of the torch to check whether the small water tank was intact and there were no cracks.

Seeing that the small water tank was intact, she tapped it again, and the small water tank immediately made a crisp sound.

Su Meng's face was overjoyed, and the confidence in her heart soared to [-]% in an instant, but she still had a calm look on her face: "Su Xiang, Zhang Lin, Bo Jing, you three take these pottery back home and make it Leak test, if there is no leak, it means it can be used."

"No problem." "Okay." "Yes, sir!"

The three answered in unison.

After carrying all the pottery back to the shed, the five of them gathered in front of the wooden table, staring nervously at the bottom of the small water tank.

They have been busy all day, and now it is finally time to accept the results.

After a few minutes passed, the five looked at each other and smiled.

Yep, no leaks, done!
Su Meng quietly breathed a sigh of relief, today's busyness is meaningful and worthwhile, so she chuckled and said, "Get ready, line up for a hot bath."

She clamped several pieces of red-hot quartz stone into the small water tank with wooden clips, then carried the small water tank out of the wooden shed and put it in the bathroom, and then she pushed the water pipe of the bathroom over.

"Zizzizi..."

The moment the cold stream water touched the hot stone, there was a sound of evaporating water vapor, and wisps of white smoke drifted from the small water tank, and the water quickly submerged the hot stone.

This is the method Su dreamed of, using the heat transfer principle of zeolite to boil water.

The old rural people in the past also used this method to boil water, and some modern steam rooms also use this method, but most of the steam rooms use pebbles, because the pebbles are smooth and clean.

in the live room.

"What the hell is it so simple?"

"There is a famous historical dish - stone soup!"

"No wonder the premise is to have a small water tank. It turns out that the heated water is enough to take a bath, otherwise it is a tasteless ah."

"Su Meng is so smart"

"Su Meng is too versatile and awesome!"

"Damn water can still be boiled like this? You have learned a lot."

"..."

"Try the water temperature." Su Meng signaled to Du Jiayue, who looked excited, to reach in and touch the water in the water tank. Everyone is used to different temperatures. Some water temperatures are just right for her, but others may think they are too warm. hot or too cold.

One of the disadvantages of using stones to heat water is that the temperature is not easy to control. If you put too much water in the stones, it may be boiled directly, and if you put less water, the temperature will not be enough.

And there is another point to pay attention to in this method, that is, to choose the right stone, otherwise the stone will break when it expands with heat and contracts with cold, and the splashed stone fragments can also cause great harm to people.

In order to solve this problem, Su Meng specially chose quartz stone, which is not easy to break when heated and cooled, and porous or lamellar stones should be avoided.

As for the water temperature, there is no other way, but whoever uses it to measure the temperature, anyway, after a few more times, you will have experience.

Du Jiayue lightly poked the steaming water surface with her finger first, and felt that the temperature was not as hot as expected, then put her whole palm in and stirred it a bit: "This temperature is just right!"

"That's fine. You can take a shower. After washing your clothes, wash them in hot water instead of cold water." After Su Meng warned, she exited the bathroom.

"Yeah! Got it! It's cold outside, go back to the wooden shed to warm up by the fire, I'll call you after I wash up." Du Jiayue replied heavily, humming a little song and enjoying the first hot bath in the wilderness.

The moment the hot water poured on her body, Du Jiayue felt so happy that she was about to scream.

She really likes Su Meng, how can Mengmeng be so powerful!She must be the first on the show to take a hot shower!
At this moment, she once again felt that today's hard work and busyness were all very worthwhile.

"It would be great if I could build a big wooden barrel in the future, like the one in TV dramas, and then I can take a bath~"

Du Jiayue took a bath happily, but her thoughts drifted further and further away.

After she took a shower and told Su Meng this idea, Su Meng actually nodded in agreement with a serious face.

Not only did he agree, but he also carefully analyzed the follow-up plan and the time and materials needed to make the big wooden barrel with her.

"It is impossible to make large wooden barrels in a short period of time, but after we have almost finished the basic construction, we can start to build some entertainment and leisure places, such as steam room?"

"As for the production of wooden barrels, the most indispensable thing in the jungle is wood, and the waterproof joints can also be glued with turpentine. Apart from the time-consuming, there are no other disadvantages."

"And if there is a big wooden barrel, the wooden barrel can be filled with water during the day and exposed to the sun, so as to get warm water, and then this warm water can be used for bathing by Zhang Lin and the others. Boys have low temperature requirements for bath water anyway. .”
