Liang Jian: I have a canteen

There was no light source in the darkness, so even with Xu San's exceptional eyesight, he could not see anything.

After completely losing sight, a subtle sense of weightlessness makes the body feel somewhat weightless.

This feeling made him feel dizzy, and he immediately took out a flare. After twisting and turning it, the flare immediately emitted a pale blue light.

The faint blue light instantly illuminated an area of ​​about five meters.

The light was neither strong nor glaring, but it broadened their field of vision.

The room wasn't very big to begin with, so a five-meter illumination range was perfectly adequate.

Huanji turned to look at the fluorescent flare stick in Xu San's hand, and finding that there was no longer any flame, she asked, "Is this made of fluorite?"

After saying that, he muttered to himself, "No, fluorite doesn't have such a large light-emitting range."

"More or less!" Xu San did not specify the exact materials used in this product.

Well, actually he didn't know the specific recipe either, because this thing was one of a bunch of tools that the second monkey had prepared for him in the future.

Huanji continued to stare at the glow stick and noticed words on it, but the words were too small for her to read. "What does it say?"

"Instructions for use!" Xu San glanced at the glow stick in his hand, then turned it around. "Oh, right, this thing is waterproof."

"Waterproof, that's good! But why are you telling me all this?"

"I'm just telling you what other advantages it has," Xu San said casually, then raised his glow stick. "There should be a light here; let's find the switch."

The glow stick in Xu San's hand emits light through a chemical reaction, not through combustion.

This reaction is called chemiluminescence.

A standard lighting bar typically contains the following components:

The outer tube is usually made of flexible plastic. The inner tube, a more brittle glass vial, is sealed inside the outer tube.

As Xu San examined the glow stick in his hand, he wondered if he could make some money from it.

Once you're in an island nation, it's best to start your own business.

I took out the instruction manual and, with the help of the dim light, glanced at the ingredient list.

There are no detailed proportions, but there is a list of ingredients.

The outer tube contains a dibutyl oxalate phthalate and a fluorescent dye.

The inner glass bottle contains hydrogen peroxide solution, commonly known as hydrogen peroxide in hospitals.

Rotating or bending the internal plastic rod will break the internal glass tube, causing hydrogen peroxide to mix with the oxalate solution. The hydrogen peroxide oxidizes the oxalate, and the reaction produces a high-energy intermediate. This intermediate then transfers energy to the fluorescent dye molecules, causing the dye molecules to jump to an excited state. When these molecules return to the ground state, they release energy in the form of photons, thus producing bright light.

Xu San nodded, feeling that his recent intensive chemistry study had not been in vain.

If Fatty Dong were here, he would probably be able to analyze the formula in no time.

"Do you still have this?" Huanji asked.

"That's all. I only brought one with me when I came out."

"You mean there are more in the cabin?"

“There are a few left. These were left to me by my teacher. They’re not for sale!” Xu San said firmly.

Huanji took out a flashlight and started looking for the switch. "I'll get it myself if I need it. It doesn't cost money, so it doesn't count as buying it."

"Uh..." Xu San turned to look at Huan Ji, "Your conscience is really bad." (End of Chapter)
