Deserted Island Live: Start with an island

"The reason is simple. The dirty coarse salt that is boiled cannot be eaten directly. There are many impurities in it that are harmful to the human body. If you eat too much, it will easily swell. It needs to be filtered. It's just that we didn't have a suitable filter tool before."

As he spoke, Lin Chuan tore off the film covering the new airdrop box.

A white object was taken out of it.

"Look at what I found in this airdrop?"

Lin Chuan held the thing and waved it pretendingly in front of the camera.

"Now that we have this thing, we can filter out refined salt."

【what?Anchor, are you kidding, haven't you studied chemistry?You tell me this thing can filter coarse salt? 】

Chapter 57 Anchor Are You a God?

As soon as the barrage appeared, some old viewers in the live broadcast room spoke.

[Hehe, a lot of newcomers have come here these two days, and someone dares to start mocking Lao Lin again? 】

[Sorry, I entered the live broadcast room a few days ago, and watched the famous scene of Lao Lin cheating on his corpse and slapping his face! 】

[Then you still dare to mock? 】

[Because this is a matter of common sense, okay?

Anyone who has been to high school should know that the purification of coarse salt is a complicated process that requires the use of many kinds of equipment, right?At least there must be filter paper!After all, the first lesson in high school chemistry is the purification of crude salt!

Is it too whimsical to filter the coarse salt with a white cloth?

This is not something that can be done with good craftsmanship!

This has already involved the most basic scientific knowledge. If the anchor can still slap in the face, then he is a god! 】

[666...Anyway, I'm not educated, I don't know, I don't care about anything else, I just believe in the truth of this live broadcast room, don't say that Lao Lin took out a white cloth today, he just used his underpants to filter it, I believe it He can do it! 】

......

in the cave.

While the audience was discussing, the pottery cauldron filled with seawater beside Lin Chuan was already boiling.

However, because the heat conduction effect of Tao Ding was not good, even though Lin Chuan burned the fire very vigorously, the process of boiling salt was still very slow.

It took about half an hour, and with a lot of heat transpiring, the water in the cauldron finally boiled dry, and a whole piece of gray crystals, about the size of a small apple, precipitated out at the bottom.

Take the gray crystal out of the tripod and show it to the audience.

"Look, everyone, unlike the white fine salt we usually eat, this gray opaque crystal is coarse salt."

"Actually, due to technical limitations, the salt that ancient people ate was this kind of coarse salt. Not only did they have to chop it into small pieces, which was very troublesome, it also tasted very bad, and it was easy to be poisoned!"

"So, do you know why our country's food uses so many ingredients such as onion, ginger and garlic?"

[Hmm..... because the salt is less, which increases the taste? 】

"That's right, this audience member is absolutely right!"

"Of course people in ancient times knew that coarse salt is harmful, but there is no way to purify it, so they can only eat as little as possible to avoid poisoning."

"The same is true for people in other countries, but most of them choose not to eat salt, but to eat sugar, so now, they still prefer sweets!"

I gave the audience a wave of science (zhuang) general (bi), and received some rewards.

Lin Chuan happily picked up the Tao Ding, and brushed it with fresh water scooped from the airdrop box.

Then use stones to smash the coarse salt crystals placed on the leaves!

Feeling almost done, Lin Chuan brought the kettle again and poured the powder into it.

Add clean fresh water to the kettle and stir it quickly with a wooden stick.

Don't stop until the water turns cloudy and the kosher salt powder is all dissolved.

At this time, Lin Chuan brought a piece of white cloth.

"Okay, the next step is to filter!"

"As you may know, generally a solution such as barium chloride is added to the coarse salt solution to allow it to react with the impurities in the coarse salt solution to form a precipitate, which is then filtered."

"But we don't have those solutions, so we have to use other methods!"

With that said, Lin Chuan folded the white cloth.

"Actually, even the impurities dissolved in water are invisible to the naked eye, but they still have a certain size. They are like existing in the microscopic world, one by one very small tadpoles, swimming around in the water."

"So, if there is such a filter, the filter holes on it are very, very small, reaching the nanometer level, which is smaller than the diameter of those impurity molecules or ions, and they can actually be filtered out!"

[Anchor, you said, it’s no problem, but using nanotechnology to purify coarse salt, is this money to burn?Moreover, you don't even have new underpants now, where did you get nanotechnology? 】

Lin Chuan shook the white cloth in his hand.

"This is nanotechnology!"

【Um?Did you get scared out of your mind by the water monster yesterday?Isn't this tm just a piece of white cloth? ! 】

Lin Chuan smiled slightly.

So the question is, is this really an ordinary white cloth?

of course not!

Because behind every prop in the Shark Fighting Mall, there will be a corresponding introduction.

So when Lin Chuan has nothing to do these days, he will go shopping in the mall and look at them one by one.

Most of them are things that can be produced with modern technology.

Part of it is beyond modern technology!

For example, the previous 'Super Antibiotics', and this piece - [Nano-level super-equal dense gauze]!

However, when Lin Chuan first discovered this thing, he felt very tasteless.

Xin said that this thing looks very high-end, but apart from being more airtight than ordinary gauze, what is its use?

Until, he remembered what he learned in high school chemistry, the diameter of molecules or ions of harmful substances in coarse salt!

Moreover, the density of this cloth, that is, the size of the pores between the lines, can be customized!
