Because there was no accurate electronic scale, Art could not accurately mix the thermite in the target ratio. He had to rely on some memories from his time on earth and reluctantly used his hands instead of weighing the scale to roughly mix a bunch of thermite.
Relatively inferior thermite is used, and although rust is common, it is difficult to increase the amount once it is collected. So now that the rust is used up, there is still a lot of aluminum powder left.
"Okay, that's about it." Art dusted his hands and poured the mixed thermite into a prepared jar. It took up less than half of the jar, which was more than enough for making grenades.
"But since you are making grenades, you need an oxidizer..." After Art installed the thermite, he began to think again.
As for oxidants, the only one that can be easily obtained in this era is saltpeter. But I have never even heard of thermite, which uses saltpeter as an oxidant, and I don’t know if it will have any side effects.
...but what the heck, just give it a try.
"Okay Ravens, you can try to make it into a bomb." Art stretched out, clapped his hands, cleaned the residue on his hands, and said, "But remember to add some saltpeter in it."
"Why do we need to add saltpeter?" Corando, who was watching carefully from the side, asked doubtfully. In the previous explanations, Art had clearly stated that the thermite only requires aluminum and specific oxides.
It didn't say to add saltpeter, but this time it said to add saltpeter. Is there any difference?
"That's a good question." Art turned around, ignoring the confused Ravens, and sat upright on the ground and said to Corando: "You should still remember what I said yesterday, right?
The part about oxidation.”
"Uh... wait, wait, the words you said at that time are really a bit too unfamiliar. I have to, I have to recall it carefully," Corando covered his forehead in pain and began to recall bit by bit.
Those words that Art said yesterday and their meanings.
"Iron will rust when... it slowly turns into air... Is that so?" After thinking for a long time, Corando finally uttered some incomprehensible words.
Is the oxidation reaction recorded as oxygen? Girl, if this is really the case, there won’t be many things on the earth that you can step on... After hearing Corando’s answer, Art seemed a little dumbfounded, let alone
After hearing this, Ravens actually looked like he suddenly realized what he was doing. He was really someone else...
"Of course not. Let me give you an example." Art raised his index finger, as if a teacher was teaching a class, and said: "The aggregation of substances is not a simple addition, subtraction, multiplication, and division. It's like
A cow eats grass, but after eating the grass, it grows meat instead of grass."
"...In other words, has this turned into something completely different?" Corando is indeed a magician, and he understands it very quickly.
However, since there are positive examples, the negative textbooks quickly stated their opinions.
"But what do you mean, what if the cow eats up all the grass?" Ravens spread his hands and said doubtfully: "Beef is beef, grass is grass, these two things are completely different! In that case
When the cow eats up the grass and turns it all into meat, will the world soon be completely bare?"
"So is grass extinct now?" Art suddenly felt a little angry and laughed. Ravens' questions were always so cynical, and he actually asked why cows ate grass to extinction.
manage…
"No, no, although it is indeed a large desert here, but... there is still a lot of grass in other places..." Through Art's reminder, Art finally understood the fatal mistake in his question. In the face of the facts, this question
It's not true at all. It's like asking whether the taller ones will die first if the sky falls.
"But it just so happens that this problem can be used as an example of redox reaction." Art raised his second finger and made a V shape.
"Continuing with the cow that just ate grass, it ate a lot of grass and finally grew fat, and it was the time to be slaughtered. Then it was slaughtered and turned into pieces of delicious beef before being served
At the dinner table of a certain white-haired witcher apprentice."
"Ha, you're on stage." Corando gloated and mocked Ravens, who snorted disdainfully and ignored him.
"After he ate the beef, he went to the grassland not far away to deal with the wolves that were stealing livestock. After moving the errands, the beef in his stomach was almost digested. When he saw no one nearby, he squatted down on the spot.
He took off his pants——"
"Uh, what a bad habit..." Corando stepped back politely, keeping a safe distance from Ravens.
"You, you guy, you are trying to smear me!" Ravens' face turned red and he pointed at Art's face and cursed.
"I didn't say it was you, so don't take your seat." Art sneered, and then told the story he had just interrupted: "After a comfortable meal, he put on his pants and left leisurely, leaving behind something
The thing sat alone on the grass for weeks."
"And one day, the herdsman of the herd saw that the grass had become very lush in a certain area of the meadow, so he took his cattle to graze on that meadow, and he also wanted to sit on the lushest grass and rest.
Suddenly, I didn’t expect that as soon as I sat down, I was sitting on a mess of mud with a foul smell.”
"The oxidation reaction is almost like this. When an object is oxidized in the air, it turns into another substance completely. But as long as the method is correct, the oxide can also be reduced back to the original substance. This is redox. Do you understand?"
After Te said, he glanced at Kelando.
"Uh, um... I almost understand." Kelando nodded in confusion, his eyes suddenly filled with confusion. This world has a tradition of using excrement as fertilizer, and crops that have been fertilized grow better.
It is also common sense, so for Corando, there is no problem in understanding Art's story, but the problem is that she has never understood the secret contained in it...
"But after you talked so much, you still didn't talk about the use of saltpeter." Ravens even gave up thinking after mentioning the 'white-haired witcher apprentice' and regarded it completely as a
Art discredited his own joke and only vaguely remembered the beginning of the problem.
"It's very simple." Art spread his hands and said: "The role of saltpeter is the role of the witcher in my story. The 'excrement' can be used as a kind of fertilizer, but in fact, the cow is directly slaughtered and thrown into the
It also rots on the ground and is also a kind of fertilizer. However, when the witcher eats the beef and excretes it, it accelerates the process of 'cow rot' and turns it directly into fertilizer."
"The role of saltpeter is to provide an environment for thermite to burn and accelerate the combustion efficiency. In the same way, the same is true for the saltpeter in gunpowder."
