Hearing this, before Ah Wei could say anything, Li Qi beside him clapped his hands and hooked Elson's neck:
"Well, what else can we do? We can just collect some firecrackers ourselves."
"The fireworks show, although it's called fireworks in name, that thing isn't loud enough."
"If we really want to talk about louder things, we have to use the traditional firecrackers from our Dragon Country."
As he spoke, Li Qi revealed a nostalgic expression:
"I don't know. Have you heard of firecrackers and firecrackers?"
"We used to play this when we were little."
"It's no exaggeration to say that the sound is so loud that it shakes the roof tiles. Compared to the noise of fireworks, firecrackers and firecrackers are what real men should set off."
"Especially the bombs, which are used to fry fish in the water. They are very accurate. Just light them and throw them into the water when they are about to explode, and the fish will immediately come up."
“It’s a must-have for barbecue.”
"As for the double-kick firecracker, although it is not as powerful as the firecracker, it is like a small rocket with a two-stage propulsion device."
"It was such a delight when I heard it explode in the air."
"We want to make this kind of firecrackers."
"What's the point of just setting off fireworks and other sissy things?"
Looking at Li Qi dancing with joy, as well as the boys from Class 9 who also looked excited and the girls who looked a little helpless, the European high school students were numb.
If they heard correctly, these guys wanted to use gunpowder to make a kind of firework with a certain lethality?
And it’s already on the way to production?
Are those gunpowders in the corner the process?
Do these guys have some misunderstanding about fireworks?
Is this something that high school students like us can make?
Don't they know that gunpowder is dangerous?
We are still on this wooden boat. Aren’t they afraid of accidentally setting the boat on fire?
Also, what about their class teacher? Why don’t you speak up and take care of it? !
Subconsciously, these European high school students began to search for Ren Yan's trace, but when their eyes caught sight of the fire extinguisher again, they were confused.
Maybe, maybe...
These guys actually...
Unexpected calmness?
"Even if you want to do it...Isn't this thing a bit too dangerous?"
"Gunpowder is not so easy to control."
Borg couldn't help but twitch his lips a few times and asked:
Hearing this, Wang Bo waved his hand:
"Hey, that's not that difficult."
"We are not making real explosives, nor are we making traditional black powder like nitre, sulfur and charcoal."
"We're just improving on fireworks powder."
"Although today's fireworks powder still belongs to the category of gunpowder, its explosion function has long been castrated. If you light it, at most a few sparks will pop out, and it won't cause any danger at all."
"If we improve on this basis, the risk factor will be very low, and there will be basically no situation where we cannot control it."
"But isn't your goal ultimately the explosives?"
"Isn't this thing dangerous?"
Borg continued to ask questions.
"That's why we prepared fire extinguishers in advance."
Wang Bo shrugged and glanced at the fire extinguisher again.
For a moment, Bogden felt powerless.
OK...
What this guy said seems to make a lot of sense.
"Okay, actually you don't have to worry at all."
"This kind of thing is very common in our class nine."
"We are not rookies. We will get started if we say so."
"We are still very clear about the principles of the two firecrackers I just told you about."
Seeing that Borg and the others were still somewhat timid, Wang Bo began to explain seriously:
"For a firecracker to explode, the power it needs comes almost entirely from the volume of gas diffused when the gunpowder burns."
"As long as we control the amount so that it can just break through the shell and create a crisp sound, we will be done."
"I understand the principle, but the question is, do you have the parameters?" Borg scratched his neck in confusion.
"No~" Wang Bo answered seriously.
Borg staggered for a moment after hearing this, and immediately wanted to explain to the other party the difficulty of this matter so that they would give up this bold idea.
It would be fine to just set off some ordinary fireworks, why do we have to make firecrackers?
However, the moment this thought came to his mind, he saw Wang Bo skillfully take out a notebook from his waist, open it and start talking:
"But parameters are not difficult to obtain."
"We can now use the thermal expansion formula to calculate the expansion force of fireworks gunpowder, and then calculate the bearing capacity of the cannon shell we made."
"Then with just a little division we can get the optimal amount of gunpowder."
"But considering the volume, we also have to optimize the ratio of fireworks powder."
"There's no shortcut to this. We can only calculate the amount of gas discharged through combustion little by little."
"We have prepared the flask in advance for this."
"So as long as you think carefully, it's not very difficult to come up with a perfect new ratio through fireworks gunpowder."
As he spoke, Wang Bo wrote a few more words in his notebook and then handed it to Borg.
Borg took it in a daze, and then he became stunned.
