Chapter 58 Saltpeter
The days pass in an orderly manner.
The temperature is also rising in an orderly manner day by day.
The bright sunshine in August makes us realize that this is probably a summer contracted by the Flaming Mountain.
There is no trouble of seasonal changes in space, but no matter what, I still have to stay outside for eight or nine hours every day. Especially the naughty kids, dog, rabbit and two old hens in the family seemed to have lost their temper due to the heat.
At one point I thought I had just traveled through time, or perhaps it was due to the scorching heat. After asking Ah Zhan in a roundabout way, I found out that it's like this every year and it will pass if you just hold on.
That’s right. In that era, apart from fanning oneself, there were no other electric fans or air conditioners like those of later generations.
Miss Jun's tsundere attribute comes out. Hey, how can such a small thing be difficult for me? As soon as the thought came to his mind in the space, he decisively searched for "saltpeter" in the mall.
The omnipotent mall has never let me down except that it was a little dark when it came to recycling items.
A piece of saltpeter about the size of a palm only costs one point. Quickly exchanged for 3,000 yuan.
What is this for, you ask? ? ? You can learn about the method of making ice with saltpeter. The simple application principle is: when saltpeter dissolves in water, it absorbs a large amount of heat and can cool down the surrounding water until it freezes.
However, due to the existence of refrigerators, this method of making ice had no room for use most of the time. Perhaps the most common opportunity to be mentioned is in chemistry class in school, where potassium nitrate is used to make ice.
Put the saltpeter into several wooden boxes, go out to the basement of the utility room, take out the boxes one by one, and then arrange them neatly.
Also taken out from the space were a dozen wooden basins of different sizes.
When she came out of the utility room again, Jun Qingqing was holding three large and several small wooden basins and a large bag of saltpeter.
When A Zhan heard the noise outside, he came out of the guest room listlessly and saw Sister Jun taking out a bunch of things from the utility room.
Out of curiosity, I didn't rush back to the house. As a result, magical things happened in the following period of time.
Sister Jun first cleaned the three small wooden basins with water, and then put some unknown things into the three large wooden basins. Even though they didn't know what these things that looked a bit like glass were, it didn't stop the children from enjoying the fun. They listened to Sister Jun's explanation of what kind of stone they were made of, and then she said: Pour in clean water in a ratio of one to three.
After doing all this, a smaller wooden basin was placed in the middle of each large basin, but the strange thing was not put into the small wooden basin.
As time passed, the water in the basin began to be covered with a thin layer of ice, and slowly the ice became thicker and thicker.
At this time, A Zhan couldn't remain calm at all.
"Wow, Sister Jun, you are simply the most amazing person."
Jun Qingqing smiled and replied, "Bring an ice basin to your room. This ice cannot be eaten. It is placed in the room to cool you down. When the ice in the big basin solidifies, we will wash some fruit and cut half a watermelon and put it in the small basin. You will have iced fruit to eat in a while.
Sister Jun will make some mung bean soup later. After it cools down, you can also put it in a small bowl and make it ice. There are many more ways to eat it, wait for sister Jun to slowly explain it to you. But we can't be greedy for the coolness. You should eat as much as we give you. You can't eat more secretly. If you are discovered, you will be deducted delicious food. ”
The little guy quickly expressed his position and said he would strictly follow Sister Jun's request.
"Now, we'll put one basin of ice in each of our rooms. And leave one basin for Dahei and Erhei in the outer room."
As for the chickens and rabbits outside, well, they worked hard to persevere.
At around four o'clock in the afternoon, Jun Qingqing went out and visited the cave. He bought another 700 pieces of saltpeter and divided them into two boxes and placed them in the cave. There were also six large wooden tubs and six small wooden tubs.
Since we found this cave, we have placed any things for the old man that are inconvenient to carry in person in the cave. The explanation given to both sides was that they bought the items bit by bit from the black market, and only transported them to the cave when they had enough.
When I went to my grandfather's house that evening, I specially put chilled fruits in a basket and wrapped a few ice cubes in cloth to ensure that the fruits would still be chilled when the elderly people and two uncles could eat them after dinner. Similarly, in addition to dinner, there were two army green water bottles in the schoolbag, which of course contained iced mung bean soup.
After the elders finished their meal, Jun Qingqing took the basket and handed the fruits to them. The shock on their faces the moment they took them was definitely not fake.
The little girl felt so accomplished that she giggled for a long time.
After laughing, he told everyone that there was more than that. In the cave in the back mountain, there was saltpeter and basins for making ice prepared for them. The method and operation steps are explained in detail, and it is specifically mentioned that the portions for both sides are prepared. Don't take the wrong one. There are notes on the boxes of saltpeter to distinguish them, mainly because there are more people here and the amount of saltpeter prepared is more than that of Grandpa Bai.
But feel free to use it, there are still plenty of them at home. Don't worry about not having enough.
