Chapter 446： 446, saltpeter ice

The morning sun was not too hot, so Muyi walked leisurely to the foot of the mountain.

The loose skirt makes her feel cooler. Although she is more than five months pregnant, she has not gained much weight except for a rounder face and a bigger belly, and her body is still well-proportioned. Consistent.

Therefore, even if you wear a particularly loose skirt, you can vaguely outline your figure.

Mu Yiren strolled around the foot of the mountain, and then went home with a hare and a pheasant. Of course, the speed was not so fast. She took the chicken and rabbit out of the system ranch.

The most animals in the pasture are chickens and rabbits, because these two breeds are the fastest.

Since there are sufficient stocks in the ranch, of course, she will give priority to the game in the ranch. She has such a task today, and she will finish it early, so she doesn't have to hang around in the sun.

After just a short time out, she already felt a little sweaty. If she worked in the sun all day, her body would not be able to carry it.

The Muyi people couldn't help but think of the villagers who were busy with construction work by the sea. The frame of the house has been completed, and it is currently growing on the roof floor.

Although the location is close to the sea, a sea breeze occasionally blows, which can slightly relieve the sultry feeling in summer, but in such a hot weather, you are still doing physical work, and there is no shelter or something to escape the heat, so it is probably still very hot.

Mu Yiren kept walking, thinking about how to reduce the heat for everyone.

The air conditioner has not been produced, the fan has not been installed, and there is no refrigerator to get some smoothies or popsicles.

etc!

ice?

It seems that this is not impossible!

Muyi returned home with a face full of joy, ready to try it in the afternoon.

Everyone in the Qin family looked at Mu Yiren with a chicken in his left hand and a rabbit in his right, but they just glanced at them and then withdrew their gazes.

Now, in response to this situation, they can at most secretly say: Oh, there are two game harvests today!

That's all!

There is nothing to be astonished about anymore.

After lunch, the Muyi people were ready to start experiments.

Today, she only has one task of contributing game, and after completing it, the afternoon will be very leisurely and relaxed.

"Mother, can this water tank be temporarily used for me?"

Mu Yiren pointed to the water tank with half well water left in the kitchen room and asked Huang Qiuhua for his opinion. There are two large water tanks in the kitchen room for daily water use at home.

Huang Qiuhua was packing up tomorrow's ingredients. He heard the sound and looked at it, and asked casually, "Xiao Yi, what are you doing with the water tank?"

Mu Yiren smiled mysteriously, "You'll find out later."

Hearing this, Huang Qiuhua smiled and didn't take it to heart. Anyway, her little Igu is very strange, and there are many strange and ghost ideas in her mind.

It is estimated that this is to come up with some new tricks, in short, she is waiting.

Later, Muyi took out a brand new porcelain basin from the house, filled the basin with water, put it into the water tank, and then picked up a small bag and poured some transparent water into the water tank. Prismatic crystals, very small granular.

After it was done, Mu Yiren told the three people in the kitchen.

"Mother, sister-in-law, sister-in-law, this water tank can't be moved by anyone from now on~"

Liu Xiaocui was busy making sauces, and said casually, "I know!"

Huang Qiuhua smiled, "I'll show you."

Muyi went back to the house and took a lunch break with confidence.

At four o'clock in the afternoon, Mu Yiren was half leaning on the bed, looking at the maternity and baby books, and suddenly heard a squeak outside.

Hearing a few words vaguely, Mu Yiren looked down at the time on the watch and showed a clear smile.

The experimental results should be acceptable!

Mu Yiren got up and put on his shoes and walked to the stove. As soon as he was halfway there, he saw An Le in a hurry.

"Sister-in-law three, you came just in time. Mother asked me to tell you to hurry to the kitchen!"

"Well, I'm getting ready to go!"

As soon as Muyi walked into the stove, he saw people standing in front of the water tank.

Liu Xiaocui asked eagerly, "Third siblings, what are you doing? Why is the water freezing on a hot day? What a strange thing!"

At noon, after the Muyi people went back to the house for a lunch break, they followed them to the lunch break. After all, the weather is so sultry, if you take a nap if you don't sleep, you will look very uninspired.

After the lunch break, it was already around 2:30. They continued to go back to the stove to work, and no one noticed the changes in the water tank for a while.

Until Liu Xiaocui wanted to draw a basin of water and came to another water tank, she thought that the three younger siblings were so mysterious, so she curiously looked at the other water tank.

Seeing this, Liu Xiaocui was so frightened that she suddenly screamed, and even rubbed her eyes. She suspected that she was blind and hallucinating!

How can there be a basin of ice cubes in the water tank!

Liu Xiaocui's screams attracted Huang Qiuhua and Chen Chuncao in the kitchen, and Qin Anle and Goudan who were sitting by the door of the main room.

Huang Qiuhua couldn't help but said, "What's so strange!"

Don't even look at who her family Xiao Yi is, is it difficult to make water freeze?

With a swipe of a spell, you will become an ignorant person!

Chen Chuncao was somewhat rational, "Third siblings, at noon, I saw you poured something into the water tank. Did you make this ice cube?"

Qin Anle was also full of curiosity.

"Sister-in-law three, can you make water freeze into ice cubes in summer?"

This simply shattered her common sense of three views. I only heard that winter is cold, and the temperature is too low to cause water to freeze into ice, but in summer, sweat is flowing.

Under such a big sun, it is completely the feeling of being exposed to the sun, and many things will be melted by the heat. How could the well water still freeze into ice cubes?

It feels like this is totally against the theory of nature!

Muyi said with a smile, "Of course you can, didn't we still grow vegetables alive in the winter?"

The chemical name of saltpeter is potassium nitrate. When saltpeter dissolves in water, it absorbs a lot of heat and cools the water to a freezing state, so the water in the small basin freezes into ice.

The method of making ice with saltpeter has existed since ancient times. After the saltpeter is dissolved in water, the cooling crystallization method or the evaporative crystallization method can be used, and the saltpeter can be extracted and reused.

As for the proportion of saltpeter for ice making, there is no specific data ratio. If it is not frozen, the amount of saltpeter can be gradually increased, and the saltpeter used is recommended to be replaced by chemically pure ammonium nitrate, which is a professional chemical reagent, and the effect is more obvious.

The impatient Liu Xiaocui couldn't hold back.

"Third younger siblings, don't sell your shit, how did you do this?"
