"Gunpowder too?" Ravens raised an eyebrow. Although every witcher is an explosives expert, the so-called expert does not mean knowing more about explosives, but means using the knowledge of gunpowder and combining it with other materials.
Make alchemical explosives with different functions.
As for gunpowder, they only know the formula. They know that mixing charcoal, sulfur and saltpeter in appropriate proportions will quickly produce a large amount of gas, but they just don't know why these things have such an effect when mixed, and they don't bother to explore.
"Of course, if you think about it, ordinary sulfur and charcoal can also burn in the air, but if you forget to add saltpeter when mixing gunpowder, what will happen if you put it in a bomb?"
"The bomb couldn't explode, and the gas was leaking out bit by bit..." Ravens said thoughtfully... As a demon hunter apprentice, he naturally made several mistakes when learning to make alchemy bombs.
, one of them was that I forgot to add saltpeter when mixing gunpowder, and the resulting bomb had no reaction at all after being ignited. After the fuse was burned, it just slowly steamed, and then stopped after a while.
"Yes, this is the role of saltpeter." Art raised his third finger and said: "Almost all combustion requires the support of oxygen, and the amount of oxygen determines the combustion efficiency. And if you want aluminum
For the thermal agent to fully burn in a closed space, an efficient combustion accelerant is necessary, and saltpeter is used for this purpose."
"But didn't you say you need...oxygen? Why do you need to add saltpeter?" Kelandu said the word 'oxygen' with some difficulty, and asked doubtfully. Because there is no word oxygen in this world, so he said
It was air and it was a bit too loose, so Art directly changed the pronunciation of oxygen in Chinese, which made people like Kelando who were accustomed to the tongue-wagging way of speaking in other worlds very uncomfortable.
"Well...this involves a lot of reactions, but to put it simply, you can get oxygen by heating saltpeter~" After saying that, Art stretched again and finally explained some knowledge points clearly.
, this group of people are beginning to understand this without even learning the basics of chemistry, which is a bit difficult for them.
"I generally understand..." Kelandu pinched his chin, his eyes gleaming with a little light of thought. Anyway, no matter what, he would buy some saltpeter and heat it up to see what the so-called 'oxygen' is.
"Okay, okay, I don't understand what you are saying at all. I just need to know the recipe." Ravens admitted without shame: "With the materials, I can make one tonight. Hmm.
, what is missing now is the shell of the bomb. Hey, do you think it is better to use pure lead stone or one mixed with iron pieces? "
Sure enough, since there are already bombs in this world, lead must be used more widely, but thermite bombs are not the same as gunpowder. Thinking of this, Art immediately said: "No need for these, this kind of bomb only needs ordinary
Just wrap it with iron sheet."
The difference between thermite and gunpowder is that gunpowder uses an extremely large amount of gas quickly produced after combustion to rapidly increase the pressure in a relatively closed and solid space, and then explodes the solid shell, using the strong impact force and the strength of the shell
The fragments damage the enemy.
Thermite combustion does not produce any gas. Although the extremely hot temperature may expand the air a little, such intensity cannot form a high pressure difference or impact force, let alone use fragments to injure it.
The enemy is over. Although some regular thermite grenades have a small bomb built in to diffuse the burning thermite, unfortunately, the home-made thermite grenades currently cannot do this.
Therefore, in fact, the main thing is to ensure that the housing will not fall apart when thrown away. Even if it is made of paper, it is not impossible. But for the sake of efficiency, it would be better to spend some money and replace it with a thin iron sheet.
"Iron sheet? Can that thing work..." Ravens looked at Art with some surprise. This was the first time he heard about using iron sheet to make explosives. He subconsciously wanted to ask why, but there were enough embarrassments today.
, for the sake of his own face, Ravens held his throat.
"Thermite can produce very high temperatures, and it should be able to easily burn through the iron sheet, and then burn the people nearby..." Corandu answered this question for Art.
"Well, you are indeed a classmate of Corando. I remember him very well."
"You two are great, you two are great." Ravens said with some self-deprecation, sat back on the bed, crossed his legs and said: "After finishing this, I am the one who is going to find the giant sand scorpion.
I am the one who wants to kill it..."
"So after talking so much, you haven't even found the sand scorpion anywhere?" Upon hearing this, Art's excitement instantly cooled down a lot. He originally thought he would be ready today and set off tomorrow.
Unexpectedly, Ravens didn't even find out where the destination was.
"Hey! You can't blame me!" Ravens sat up immediately and said with some opinions: "That fat man drove me away without saying anything to me, and it was a commission he received this morning. Until now,
It’s just after dusk!”
"Is it already night? Then I have to go first, thank you very much." When Corando saw that it was completely dark outside, he simply thanked Art and left quickly.
Art and Ravens were the only two people left in the room again...
"Okay, Ravens, what's going on tonight?" After a short period of silence, Art asked boredly. He originally planned to read the borrowed books tonight, but
Because this incident made him very excited, he didn't have much patience to read.
"What else can I do? Go to the tavern, play a few games of cards, drink a few glasses of wine, and then ask if anyone knows anything about the giant sand scorpion." Ravens was also a little embarrassed, and there were no outsiders now.
Just let out some of the accumulated anger.
"Take me there, I also want to visit the tavern here." Art also raised his hand to indicate. When he was still on earth, whenever he was going to take on a big job, he would drink some for himself the night before.
Drinking wine to cheer up the brain, and now, the feeling brought by this habit has appeared again... Although the body is still a child, but a little, just a little bit, it should be okay, right?
"Are you going?" Ravens smiled angrily and said, "No one would take a child to a tavern."
"It's not too late now." Art shook his body and said, "It's easier for children to sneak into some places and do eavesdropping work, isn't it?"
