Zhang Yang, who was rummaging through the cabinets in the living room, heard He Xiaoman, who was busy in the kitchen, asking curiously, and asked a little puzzled after stopping.

"I'm looking for alcohol and DEET, I remember last time it seemed to be in the living room locker, why is it gone?"

He Xiaoman didn't know what DEET was, but she knew the alcohol, after all, she still cleaned up this thing, it seemed that she bought a bunch of medicines after Zhang Yang went out last time and stuffed it directly into the locker in the living room.

"I've put it all in the bedroom, you can go and find it, it's in the area of the clutter!"

l got the instructions of his wife, ran to the bedroom, and then quickly found what he needed in the storage space, and then happily returned to the terrace on the roof of the car.

After putting all the things he took down on the table, he looked at the drone that came back from the river and said to the fans in the live broadcast room.

"That's right, I'll mix it for you once, in fact, it's still very simple, prepare a small transparent square box or something else to replace it, and then there is the alcohol disinfectant that can be bought on the market, which is to prepare DEET and syringes. ”

After letting the people in the live broadcast room take a look at the things he placed on the table, Zhang Yang opened all the lids, and then sucked them out with a needle in turn according to the ratio.

"A small square box, filled with 30 ml of pure water, anyway, whatever water, and then add 20 ml of DEET, 40 ml of 75% alcohol is prepared, and people in need can also prepare some perfume, not too much, about 10 ml.

In this way, you can prepare a mosquito repellent water with a concentration of about 20%, and you only need to put it in a small watering can and spray it on the skin.

By the way, alcohol depends entirely on personal needs, of course, I prefer the cooling feeling brought by the evaporation of alcohol on the skin, alcohol is not necessary, after all, DEET is soluble in water. ”

Holding the needle, he easily mixed all the mixtures into a small transparent square box with water, and after stirring well, Zhang Yang poured all the liquid into a small watering can.

At the same time, don't forget to remind the people in the live broadcast room to take precautions.

"By the way, there are more mosquito repellent water on the market now 2.5%, 4%, 5%, and it is very convenient to buy, like the 20% I adjusted today, the concentration is relatively high, in fact, the effect of 10% is about the same.

And you must not think that the higher the concentration, the better the effect, in fact, the concentration is only related to the length of time.

If the concentration is high, the duration will be long, and if the concentration is low, the duration will definitely be short.

Like the one I adjusted, it can last until we finish dinner, but when you use it yourself, try to halve the dosage, the concentration is not too high, less than 10%, and it is recommended not to use it frequently. ”

As he spoke, He Xiaoman had already walked over with two dishes in the direction of the stairs, Zhang Yang hurriedly put the mosquito repellent water he had just prepared on the side of the table, and then immediately went down to serve other dishes.

When he came up, He Xiaoman, who was looking at the small watering can in his hand, looked at him with a smile and asked?

"Husband, did you get this thing out of my perfume to the point?"

Putting the other three dishes on the table, and then putting the dinner of the four little ones aside for them to solve on their own, Zhang Yang got up and nodded and said with a smile.

"Of course, I mixed a little mosquito repellent water, and it was that kind of effect, oh, it's not that I thought that there was only a mosquito repellent lamp or a little worried, so I got a little bit.

Doesn't it smell better with perfume, it's okay, your husband and I will go and bring you a few bottles tomorrow!"

......

Shi Gaoyang will be a little upset, and it is estimated that watching his favorite anchor enjoy the riverside scenery on the roof of the car can make his mood relax a little.

But the damn mosquito was buzzing next to him again.

The mosquito seems to have been pestering him since he started work in the afternoon, and he has frequently expressed his dissatisfaction and anger with his body twisting and waving his arms.

But the damned mosquito still surrounded him, repeating the monotonous buzz of indifference, as if mocking his incompetence and vulnerability.

There was no way, the workload was too much, the mosquito coils were used up, and there was no other mosquito repellent equipment, so he could only stay here for a whole afternoon.

The back of the neck had already been bitten hard, and the damn mosquito had sucked the blood and left him with a big bag, and now he could only endure the itching on the back of his neck while working, and he didn't dare to scratch it.

But I don't know how long it took, and the damn mosquito buzzed from some corner, and thought he was upset.

That damn mosquito, I guess I'm hungry again, and I just ordered a takeout for dinner to fill my stomach, this time it's more than 6 o'clock in the evening, the night is very long, the mosquito is very annoying, and he has to work overtime tonight.

Just now, that damn mosquito actually landed on his arm with impunity, and was about to pierce his skin with its long needle-like mouthparts.

Suddenly, the image of the professor wearing gold-rimmed reading glasses and holding a magnifying glass to review his documents flashed to his mind.

I don't know how long later, he was even more irritable, he simply threw down his work, turned his head to watch the live broadcast, and at this time the anchor he liked seemed to be doing some experiment.

That's alcohol? Something called DEET.

Is this an idol preparing mosquito repellent water?

Every step is very clear.,What things need and how much idol is also clearly described.,And then it's not an egg.,Alcohol has itself.,There seems to be a needle or something in the medicine box.,But there's really no DEET.。

Shi Gaoyang, who had just seen a light in front of him, instantly lowered his head again.

The door to the office was suddenly opened from the outside, and when I turned my head, I realized that it was the professor who had walked in with something in his hand.

"Xiaoshi, look at what this thing is? I don't know who put it in my office some time ago, I see what benzamide is written on it, it can't be a chemical, right?"

The professor was teaching history, and he walked in with great care, gloved and holding a bottle of liquid.

I vaguely heard benzamide what Shi Gaoyang vaguely remembered the chemical name of DEET when he watched the live broadcast just now, his eyes lit up, and he quickly got up and walked to the professor, and then took the bottle of liquid in his hand.

N,N-diethyl-3-methylbenzamide!

It's DEET, although I don't know who threw this thing into the professor's office, could it be that other seniors have used this thing before?

Forget it, no matter, this thing is really timely!

"Professor, you saved my life, there are too many mosquitoes in the office, and you are holding DEET, which can be used to adjust mosquito repellent water. ”

Hearing his words, the professor's eyes lit up, and he looked at him a little impatiently and asked.

"Xiaoshi, are you sure this thing can be used to make mosquito repellent water? The electric mosquito coil in my office doesn't work at all, and I have two big bags on my arm in a moment. ”

"It works, it definitely works, just now my idol taught us in the live broadcast room, and I was still thinking about where to get DEET, so you took it!"
