Chapter 447： 447, the third brother is back (1/2)

Muyi raised his lips, "It's very simple, through scientific knowledge! Didn't you see me pouring something into the water tank? That thing is called saltpeter, which is a product of nature. In short, it has many uses in chemical research."

Liu Xiaocui was very puzzled and asked with a look of surprise, "What do you mean by putting some saltpeter in the water, you can make the water freeze??"

"Yes!" Mu Yiren nodded with a smile.

Qin Anle asked curiously, "Sister-in-law three, is that saltpeter so powerful? I've never heard of it before."

Muyi replied, "Saltpeter is generally used in chemical industry, so it should not be sold to the outside world. I also did experiments before and brought some back from the Academy of Agricultural Sciences. I only remembered it at noon. In short, this is the use of science. Knowledge of how to make ice!"

She bought the saltpeter on the system trading platform in the morning, and at that time, she suddenly thought of the method of making ice with saltpeter. It is an easy way to make ice cubes at home without using any ice-making equipment.

As a third-year graduate student in chemistry, I still know this little trick.

Huang Qiuhua looked at the ice cubes in the pot and exclaimed, "Sure enough, you are still a scholar! This ice cube can still be made by humans."

Liu Xiaocui blurted out, "It's not that he is a good scholar, but the third younger brother and sister are very good. The third child is also a scholar, and I have never seen him make ice cubes before!"

Huang Qiuhua swept over with a glance, however, she was speechless, thinking about it, Xiaoyi is indeed more powerful! I used to think that the third child was very good at university, but now he looks so cowardly!

I don't know where the books have been read for so many years!

Mu Yiren smiled and hurriedly kept his third brother innocent.

"My knowledge is in chemistry. The third brother's major is different from mine. Besides, the third brother is a student, and he has nowhere to get things like saltpeter."

To sum it up in one sentence, her major is in the direction of agricultural biology and life, while her third brother is in the direction of technology and industrialization.

Although they all follow the scientific research route, the direction of research and development is not the same.

Huang Qiuhua responded enthusiastically, "Xiao Yi is right!"

Goudan raised his face and asked, "Auntie, can I eat this ice?"

"Okay, but I'll have to wait for the cool night, and my aunt will cook something delicious for you!"

As a third-year graduate student in chemistry, from a chemical point of view, saltpeter can be used as ice and can also be eaten. However, from the perspective of clinical medicine, the harm of saltpeter to the human body has not been thoroughly demonstrated.

Therefore, you can eat it. After all, in ancient times, it was the way to eat saltpeter to make ice. However, you should try to eat less saltpeter to make ice. If you eat too much for a long time, it will affect your body to some extent.

"good!"

The dog's face is full of anticipation, I don't know what delicious food my aunt is going to do? But no matter what, it's sure to be delicious.

Liu Xiaocui was still staring at the ice cubes in the basin with a look of amazement.

"It's really amazing, just put some stone **** and you can turn the water into ice, tsk tsk tsk~"

Mu Yiren couldn't help laughing, stone slag?

This thing is very capable, but unlike those ordinary pebbles, if it is to make gunpowder, it also needs its cooperation.

"You are all around here, what are you doing?"

Suddenly, Qin Dafu's voice sounded.

Mu Yiren turned around and was about to answer, but at a glance he saw the man standing beside his father-in-law!

"Third Brother!"

Mu Yiren shouted happily, and rushed to the kitchen door excitedly the next second.

"Be careful~"

Qin Mingsheng immediately dropped the luggage in his hand, stepped forward a few hurriedly, opened his hands to support his daughter-in-law.
