Chemistry

Behind the building where Jungwoo arrived, there was a lot of work to get the sound equipment and lighting out of the truck.

“Clap Chan! Move this to the side of the stage! ”

“Yep!"

The applause ran along with Jungwoo.

Equipment in a Black Iron Bag. It takes less than a minute to load the cart.

“Suzu, why are we going so fast? ”

“This is the sound of suffering from the beginning. You have to finish the basic setup before 2: 00. The singers will be here before then. ”

Jungwoo pushes the cart, and the applause starts to move, holding tight to keep the equipment steady. Through the rear door, the stage staff approaches and reveals the view from the inside.

Named Atrium, it was a circular, complex mall with open skylights and cool views from anywhere in the building.

Jungwoo stared at the center of a vast square of 450 square. It was a small construction for the stage.

Looking at the control lines to prevent customers from visiting the mall, it seemed that they also needed to place a couch chair for approximately 500 people to sit in.

“Do I have to buy a ticket to sit here and watch? ”

“It's a VIP customer draw. Ordinary people don't have chins. ”

You can watch this square from anywhere, but Jungwoo asked, in case you were wondering.

“Can I get up close and personal when I'm performing? ”

“If you have it on you. ”

Applause points to the staff pass. Jungwoo strokes his neck like a treasure trove.

“What are you so fond of? You don't even know Yoon Yi Seul. ”

“How pretty is she? ”

“Later, when you see live, you'll see why people move so fast. ”

“Just be ugly. ”

“Search for it. ”

“I'll hold off for visual and auditory shock. ”

The applause that was moving from the front seemed to make Jungwoo stop.

“Let's put it down here. Oh, I don't have to move Truss today because I'm in charge of cleaning equipment. ”

“Okay.”

Jungwoo mourns as he looks at the other staff carrying heavy iron braces. I flew it last summer. That thing is heavy.

“Hey, Dinner. ”

The director, who was stationing the sound equipment on one side, raises his head and asks Suh Chan for help.

“Is he the friend you were telling me about? ”

“Yes, sir. ”

He quickly muttered, "That's the director's brother." Jungwoo bows.

“Only woo.”

“Oh, yeah. I'm starring Kim Mu-jin today. You look like you could do a good job. Can you get the cable from the equipment truck? ”

“I'll just take this down and bounce right back. ”

After living in the lab for the past week, I was surprised by Van Jungwoo's skilled crookedness.

Jungwoo went outside of Huddak and found a cable box and put it down next to the supervisor.

“Here.”

“Thank you.”

Director Kim is obsessed with his work, along with the sound staff next to him, without saying anything else.

Applause chan, who was moving the box, nodded his head to Jungwoo. The applause opened its eyes to the coming Jungwoo.

“Are you really awake? Do you miss Welke?”

“If anyone's listening, I think they're always playing. It's just that I've been so distracted by the job specs up until this year that no one noticed. ”

“Wow, Sissy. Wipe your tears. It's like last night when you and I were hanging out at the Internet cafeteria. ”

Jungwoo smiles and lowers the remaining steel box in front of the stage.

The basic equipment move continued for the last four hours. In the meantime, the skeleton of the set around the central amphitheater is somewhat completed.

Jung watches the staff setting up the speakers as he carefully sees a box of applause coming.

“Is that a flaming machine? ”

“Well, you have to be careful with that. Put on gloves.”

Jungwoo stared at the box with a tense face, holding the symbolic cotton gloves of the labor.

Suddenly, the applause that unlocked the box and pulled out the machine said, "Wam!” I pushed it into Jungwoo, shouting. At that moment, the color was pale, so Jung flinched and retreated.

The applause giggles.

“Damn, I'm scared. ”

“This dog · · ·”

The machine that produced the flame was a simple structure that put a red cloth on it and shot air to mimic the flame.

“Put it up there. I have to get a pollen air gun. ”

After placing the equipment handed over to Su Chan on the stage, the electrical system staff picked it up and immediately started installing it.

Jungwoo then looked at the CO2 vents to see the fog machine, but did not expect to see the stage because it appeared crude.

“Hey, is this really what it feels like? ”

A round of applause comes along with a cylinder that looks like a projectile mounted in a row.

“Later, when the beams and the lights flash and the music thump, there's a commotion. ”

“I don't know. It feels better when it's dark. ”

“This is what it's gonna feel like. ”

The applause puts the equipment down in front of the stage.

“Flowers of the event. Fireworks.”

“Fireworks?”

“The fireworks inside are set by the director himself, but I'm not kidding. My mouth is blowing. I'm an expert at getting events out of this lineage. ”

At this sound, Jungwoo's gaze turned toward Kim Mujin, who was talking to the acoustic team inside the tent.

“All you have to do is press the button and make sure the spark is properly bounced. You need to rest. ”

A round of applause crouches in front of the launch table, and takes out a bucket the size of a palm.

“What's that? ”

“Test powder. I heard it's some kind of match. ”

What came out of the barrel was a bunch of paper the size of nails. The applause tears it apart and puts it inside the projectile.

"Huh?

Jungwoo stared at the contents flowing into the barrel and felt a sharp enlargement and prepared for the coming visual shock.

The first thing I saw was the elemental particulates of carbon, which looked like grains of charcoal. The elemental noise that seems like it will smell nasty floating around it is sulfur. There was a peculiar cluster of stars occasionally emitting a bright beam of light.

"This is the small universe of the gunpowder system. ’

When he put the powder in and pressed the button, a small spark popped up from the projectile.

Jungwoo searched the launchpad entrance and found traces of a previous firecracker.

The clusters of elements that stick together and spread with flashes resemble the shape of a fountain flame. Other launchers also saw compounds that left traces of biting their tails like comets.

“Oh.”

Jung was impressed briefly because it looked pretty cool.

“I'm surprised at this. I'll surprise you when I see the fireworks in person. ”

I'm not impressed by the applause, but Jungwoo smiles inside. Since I was still amazed, I felt a lot of energy on my shoulders because it was cute and salty.

“Suzu, how long can you be on stage? ”

“Not yet. ”

“It's been three years. When do I get to see my friends in concert VIP seats? ”

“There's too much to learn. Especially these boys.Choreographing fireworks is a skill you can't learn without paying money. It's not something I can do right now. ”

He tilts his head as he looks at the launch pad.

“Difficult? Why don't you just mix it up with some flour? ”

“Are you out of your mind? Do you have a stage to burn? ”

He looks at the projectile set at the applause of speaking as if it were going to be a bomb.

“Fire takes a lot of burns, and it's a small amount of complete combustion. I think it's roughly Bonnie gunpowder base mixed with strontium, flash powder and cellulose nitrite. Put all this in a nice, clean fire. One second a red flame popped up and drank. ”

“S-Tron what? ”

The applause only filled my eyes. Jungwoo, um, thought about it and organized it briefly.

“It's not hard to know the role of what powder is. ”

“How do you know that? ”

“I met a good teacher and studied. That's why I got hired as an intern. And doesn't complete combustion make sense? If you keep the oxygen high and the temperature low, you won't get soot. You know, the fire in the stove. ”

I asked again because I could barely keep my eyes open.

“Did you fall asleep in communal school? ”

“I dozed off every hour, man! You slept with the map. ”

A round of applause moved to the tent, pulsating his sweaty clothes. After a moment, he came out with a box with the letter ‘Fireworks.’

“This is what I'm practicing. Chinese fireworks.”

“It's for sale at the market. It's got a nasty spark. ”

“I ordered it in a straight line. It's not very cheap. ”

Jungwoo took a few of them from a pile of cheap fireworks and asked as he watched the applause mounted on the launch platform.

“What? You said you wouldn't do it? ”

“For rehearsal. If the event singers can't adjust to the sound of fireworks at rehearsal, they'll be startled on the main stage. ”

“Can I still hurt you? ”

“Just put in any firecracker and it's all set. And I have this career! ”

Since Yu Hee's sign is also the applause that she confidently accepts

“Thori.”

I nodded right away.

“Anyway, let's just do this and have lunch. Just wait three minutes. ”

“Yes."

As Jung silently waited for the applause that was manipulating the projectile, he tapped the fireworks in the box and looked at the empty shell with the lid open.

In the same way, you can see the small universe of the gunpowder system.

‘It feels a little cheap, but the ingredients are similar. ’

Jungwoo turns to the applause.

“Thank you.”

“Huh?"

“Can I set up one of those launchers? ”

“Khh, do you want to try it? ”

“To see if it doesn't work. ”

“What?”

“Something like that. ”

It showed the place that was written 3 times out of a dozen shots as if he was using a boxer.

“Ham it. This is for cast number three, so during Girlfriend Rehearsals, you blow fireworks. It's me, right?”

“Oh, well, thank you. ”

“The most expensive fumes · · ·"

“Applause!”

At that moment, the liver heard a voice calling out for a round of applause in the tent.

“Yes, Director! ”

“Type A hookup code and microphone, which box did you put it in? ”

“Where the boxes are stacked · · · · · · · · · · ·. ”

I looked back at Jungwoo to see if I could not applaud.

“I'll be back. Stay here."

“Yes.”

Jungwoo rummages through a crate of fireworks and picks out just an empty barrel. I scoured the powder system's microcosmos and found fireworks of the same packaging and held them in my hand.

Jung, who dared to tear the wrapping paper, looked inside.

When I looked at the actual material, I saw a more pronounced flame reaction.

A series of processes in which charcoal and sulfur heat potassium nitrate as it burns, and oxygen released therefrom is supplied to the fire.

Depending on the formulation of the materials, the reaction rate was also varied depending on the content of the metal powder.

‘They're silver rocket-style. ’

I unpacked the other packaging.

‘This is a turquoise shrapnel. ’

Considering the combustion reaction of the fireworks containing aluminum and calcium powder, a chemical formula overlapped and a new interaction was drawn before my eyes.

I uncovered the lid of the biggest fireworks.

‘This has all the colors. Smoke round? All right, let's do it. ’

Jungwoo takes a rough estimate of the reaction rate and pulls the firing line and thrusters from the combustion rocket and mounts them to the projectile, mixing the powder in the paper and setting the rest.

"You dusty bastards, stand still. ’

The [+], [-] ion reactions are promoted appropriately in the palm of the hand, and the useless free electrons are sent away.

The creation.

As far as I could match the image of the fireworks following the new scheme drawn, I opened almost all the fireworks in the box and used them.

Sweet.

Finishing up, I put the lid on the launch pad, and I saw a round of applause coming from a distance. Jungwoo, who was momentarily ecstatic, turned his gaze to the crate.

Are you finished? Stop thinking about Yuhui · · · · · · · ·. ’

In my mind, I made excuses like this, but in fact, I think it would be right to say that I am curious about a child who has never played with fire before.

But will it work? Will it work? ’

Jung was somewhat confident because there had been no errors in the world through the chemical perspective.

“Did you install it?”

A round of applause approached. Jungwoo quickly closes the box and pushes it to one side.

“Uh, roughly. ”

“Let's go. Let's get our fill and get to work. ”

Fortunately, I didn't really care. Jungwoo, who was following Su Chan, glanced at the crate of fireworks that would only contain shells and asked.

“Suzu, how much did you pay for all those fireworks? ”

“300,000?”

I can give you 50,000 won in Albany today. Jungwoo said in his heart, "I will pay you back on the wall."
