Gretel left the largest and most boring daily preparation work to the new pharmacist, and happily plunged into the alchemy room.
The two of them were busy back to back. Ringer set up the distillation device and watched the condensed water fall into the container drop by drop. After making sure that he didn't need to keep an eye on it all the time, he slipped over to see Gretel.
I was shocked as soon as I passed by: Grete squinted his eyes, held a thin quill pen, and was drawing lines on a long glass tube. The glass tube was fixed on the wooden shelf, vertically downward, with one end hanging down.
The water was rolling in the boiling hot water, and the hot steam rushed directly to Gretel's face, but he seemed to be unconscious and concentrated on drawing the line.
In the center of the glass tube, a thin bright silver thread rises straight up. The tip of Gretel's pen is at the end of the bright silver. He pulls it horizontally, then moves his steps to compare carefully. After observing for a long time, he finally breathed a sigh of relief:
"nailed it……"
Linge asked curiously. Gretel unhooked the glass tube from the shelf, carefully laid it flat, and drew a long line along the wall of the tube. After hearing Linge's inquiry, he turned back happily:
"Make a thermometer!"
"Wen...what?"
"Thermometer!" Gretel's eyes were shining. Oops, it really made his liver burst. He was stuck in the extremely hot studio, working with the jewelry craftsman - a small place where the jewelry craftsman moonlighted as a glass blower - day and night.
I had liver disease for seven or eight days!
Isn’t it just a glass pipe? One on Taobao costs less than 10 yuan, and ten of them cost 30 yuan, with free shipping and shipping insurance! But in this strange world, he has to do everything by himself!
Heating, stretching, pinching off - just this step alone will destroy countless glass tubes - then heat it, weld a short glass tube up, heat and vacuum, let it absorb the mercury. Turn it upside down, and insert ice water into the lower part.
In the middle, let it shrink to the bottom, and the top is heated and sealed...
Fortunately, the inhalation of mercury was the last step. It was placed next door and sedated with ice water. If he had worked harder, the mercury vapor could have poisoned him. Believe it or not!
"Thermometer? What is this for?" Ringer was confused. Gretel raised a bright smile:
"It indicates the temperature!"
Oops, the body temperature is 37 degrees 5 or 38 degrees 3. Finally, I don’t have to touch it with my hands...
Although a thermometer is not as good as a stethoscope or a sphygmomanometer, it can be considered a useful tool in clinical terms! Really, without tools, everything will look wrong when looking at the disease!
"Well, you see, the mercury in the glass tube expands when it encounters heat, and contracts when it encounters cold. Look, I inserted it into ice water now - does it go down? Then insert it into boiling water
Here, he ascended again.
At different temperatures, the height of mercury is different. We use this principle to indicate the temperature. Just hold the lower part and don't move it. After a while, you will be able to see the temperature of your fingers..."
The "useful thing" in Grete's mind was almost like a small artifact in Ringer's eyes. As he listened to Grete's explanation, his eyes became brighter and brighter. He held his breath and stretched out his fingertips to pinch the thermometer.
Mercury bubble. Gretel simply handed the thermometer to him:
"Try it yourself, be careful not to put it on the fire or break it. Don't bother me... let me think about how a straight line is divided into 100 parts..."
Gretel muttered and threw himself on the table, scratching his scalp desperately, recalling how to draw the tick marks. Murmurs kept coming from behind:
"It expands when it's hot... it shrinks when it's cold... it expands when it's hot... it shrinks when it's cold..."
Hey, uncle, you are very perceptive! Thermometer and the like, nothing else matters, only the four words "thermal expansion and contraction" are the essence! Grete smiled secretly and raised his voice:
"Different substances have different boiling temperatures! You can try more and use a thermometer to help control the temperature during distillation and extraction. The efficiency will be higher!"
"Yeah?!"
Ringer responded in surprise. Gretel ignored him and finished drawing the temperature mark, then turned to do the bacterial culture experiment.
The thermometer is not a valuable thing. As long as it is not smashed, you can play with it as you like. But it is more important to do experiments. From time traveling to now, he has accumulated a lot of topics!
Finally, a coolie came to the door. The most tedious tasks of making distilled water, making physiological saline, and making alcohol were thrown away. Hurry up and do experiments!
Grete hummed and arranged a stack of petri dishes on the table and put down the culture medium. Half of the petri dishes were filled with aspic and the other half with agar - thank God, he finally bought Gelidium...
Next, spread out a row of gauze, a ceramic spoon, a scalpel, and a piece of wood to make a tongue depressor. Wash your hands, and put your left hand face up on the table——
"One, two, three! Magic trick - clean!"
The light of magic tricks shines continuously on all materials.
Grete rubbed all the experimental materials, including the fingers of his left hand, on the two culture media.
Next, take out the same material that has been sterilized by high temperature and rub it on the two culture media. Finally, wash your hands, disinfect them with alcohol and dry them, and carefully press on the culture media.
"Let me think about what I'm missing... By the way, purifying diet! Water creation!"
Using sewage treated with purified diet and purified water generated by hydrogenesis, bacterial culture was completed respectively. Grete labeled each petri dish, and wrote down the source of the sample and the culture time. After doing this, he finally relaxed
After a while, I returned to the study and started writing the paper:
""On the Mage's Tricks, Purifying Diet, and the Sterilizing Effect of Water Making"... Well, let me think about it, should I go back to the Mage Tower and add the water from the water element pool for comparison..."
boom!!!
There was a sudden explosion outside the door. Grete's hand trembled, and a large drop of ink fell on the paper, immediately staining the paper:
"What happened?"
Don't let the alchemy room have a problem! The distiller is still standing there! You can't leave! There is also a sterilization room downstairs. The pressure cooker must not explode...
He rushed out desperately. In the lounge opposite, Priest Donald also rushed out with a book in his arms. There was a series of footsteps on the stairs. Alvin, Joanna, and Patrick were reading in the consulting room, as well as Little John sitting at the front desk.
, galloping up:
"What's the matter?"
"What happened?!"
"Little Gretel, are you okay?"
"I'm fine!" Gretel responded loudly. He followed the sound and rushed into the alchemy room opposite. He saw the new Lin Ge lying on the window with half of his body leaning out of the window. Hearing Gretel's footsteps, he tremblingly raised the black
His right hand, with tears streaming down his face, he cried and laughed:
"I broke through! - I broke through! I finally broke through to a level 1 mage. Wuwuwuwuwu..."
So it was you who did it just now? Gretel rushed to him and looked down. The smell of gunpowder smoke in the air had not yet dissipated. Opposite the alchemy room and below, there was a black burn mark on the roof of the bungalow, which was obviously burned by the flames. Grete
His feet swayed, and he quickly took two steps back, summoning the strong wind to blow away the smell:
"Linge! Even if you break through, don't blow up the toilet!!!"
