Chapter Fifty-Three Experiments on Gradual Interpretation of Energy
Fei Chai took out the alcohol light from the bag, which was asked to find Zhang Qi, and then took out some bottles and cans to start blending a transparent liquid. While stirring with a glass stick, he talked about In fact, more tone seems to be talking to ourselves: "Let's do an experiment first! It should be said that this experiment should go to the laboratory, because it is a bit risky, but the laboratory is too small to accommodate so many people. So? I think it ’s still doing it here. When this experiment is done, what is the energy of energy?
Fei Chai said, while debugging the liquid on the hands and feet, the debugging was blended and poured carefully into the alcohol lamp with a funnel, and then found an iron frame that was removed from the gadget. Then, there is a high -tech product that appears below, but after he takes out such a high -tech product, everyone laughed, because it was a piece of cut cake.
"What do the teacher do! I plan to eat baked cakes." Yuan Xiaoshan couldn't help it, and asked Zhang Qi.
Zhang Qi also shook his head inexplicably. He thought that if Feng Weihai was there, he was a science class after all.
Fei Chai heard everyone laugh and didn't care. Instead, I just showed everyone, "Don't laugh! From this big cake itself, there is not much technological content, but this big cake is I from dozens of pieces from dozens of pieces. Pick it out in the big cake, look at the number of layers of its layer! "He said, showing the section of the big cake, just because the distance is far away, he has a fast hand, although everyone eliminates the neck. See clearly: "It is very close to the crust structure, of course, it is not so accurate. Now let us put this cake on this shelf." He said, put the cake, and then said, "Now, we will take This piece of cake is used as a crust, and the alcohol lamp below? Even if it is the pressure and thermal energy under the crust, when the wine lamp is ignited, everyone can see an unexpected change, but I just said it just now. This experiment has certain risks. If I operate alone, I will be a little bit messy, so what about one classmate, which classmate is voluntarily come! "He said, sweeping a row of seats in his eyes. [
Yuan Xiaoshan stabbed Zhang Qi and said, "Most of them want to call you to go."
Hai Rong also thinks so. Of course, it is appropriate to use the most successful assistant, but who knows that Fei Chai finally chose a girl with a wide shoulder among the students who raised their hands. It turned out to be Feng Peipei.
Feng Peipei didn't really want to go up, but I couldn't bear the tunnels of my classmates around, and finally came up.
Fei Chai said to her with a smile: "Thank you classmate."
Feng Peipei said: "Teacher, I can't! You can teach me."
Fei Chai said, "Of course, I don't teach you, then why do I come? Actually, you have to do it very simple, that is, take this lighter ..." He said another one -time lighter "You can use this lighter to light this wine lamp."
"Oh, that's it!" When Feng Peipei was very simple, he shot a lighter with a lot of care. You had to order the alcohol lantern. Fei Chai saw it at first sight, and seemed to be panicked: "You wait, wait." Say Just hid on the podium and squatted down, blocked his ears with both hands and said, "You can order now."
He looked very funny, semi -true and half -fake, and Feng Peipei who got to get a bit dare not order, and the guys in the classroom saw this and felt funny. Someone couldn't help laughing. Fei Chai suddenly stood up. Said the classmate who laughed: "Standard, what about the experiment?" Then he said to Feng Peipei: "Okay, click."
When Feng Peipei saw what he looked like just now, the risk of this experiment was also doubtful. When I wanted to ignite, the hands were a little bit embarrassed, but the fire seedlings touched the core, and suddenly heard Fei Chai shouting: Wait, this came, and this came. It was fierce and fast, Feng Pepecuo couldn't defend, his hands trembled, and the lighter fell to the table. Everyone couldn't hold back, and finally broke out. : "Professor Fei, can you be shocked!"
Fei Chai said with a smile: "I'm sorry! I mean you are not busy, wait for me to hide, you can order again." Then, really hid again.
The students in the audience laughed, and there were some whispers, and some asked: "This is a bit like a joke! Not a real experience."
Some people replied: "There should be no risks or something. I guess at most a black smoke, and then Pepe's face is dark, and his hair is rolled."
So I listened and smiled again.
When everyone's laughter calmed a little, Fei Chai guessed that the alcohol lamp was not ignited, so he asked loudly: "Feng, did you start or not, it's time."
In fact, Feng Peipei had already ordered several times, but the alcoholic lamp couldn't be ordered, so he said, "Professor, can't order!"
Fei Chai said, "You make the fire a bit bigger, there is not alcohol there, the ignition point is high."
So Feng Peipei adjusted the amount of fire to the largest, and I ordered a few more times. It was still impossible. Everyone stretched out her neck to look at what effect. Feng Peipei at this time was too complicated. At the same time, the more scared, because she didn't know what would be "risk '.
However, no matter how hard Feng Peipei works, the alcohol lamp is not ordered, and the final Feichai is impatient. He stood up from the hidden place of the podium and said, "Forget it, it seems that some things can not be allowed to do it, not discrimination against discrimination, not discrimination against discrimination Girls! After all, gender also has its own strengths. Boys are good at explosive activities. Women's endurance is the best. Well, please do not go down now, rest next, we invite a boy to come to come to come. Complete this challenging experiment, okay, be willing to join hands. "
At that time, there were really many boys raised their hands, Fei Chai picked it, and finally picked the long thin tendons and Niu Xin of the glasses. The reason was that he was thin and the goal was small. [
When Niu Xin arrived on the podium, Fei Chai also said, "The reason why Feng Feng did not order alcohol lamps just now? It may also have something to do with the tools used, and boys need large -scale killing weapons." Get out, finally take out a spray lamp, try it first, and spray a half -foot long flame, like a small flame sprayer, everyone laughed again, Fei Chai handed the lamp to Niu Xin to Niu Xin again He taught him how to use it, and then pulled Feng Peipei to hide again. Niu Xin was about to spit the fire, and Fei Chai shouted again: Wait.
Niu Xin suddenly felt that this experiment may be a farce in itself. Many other students also thought so. Fei Chai stood up and said, "Classmate Niu, I suddenly think! This, since there are some risks in the experiment, the classmates are some of the students. What do you think? "
Students think whether they are ridiculed or serious, they think it should be.
Fei Chai said with a smile: "Actually, I also prepared the protective gear, and I forgot to take it out just now." He said again in the bag, and finally turned out a highly technological mask ,, I don't know if it was the mask of Tang Seng bought by that temple fair. Many children have this.
At first glance, everyone laughed immediately. The more and more determined that this experiment was actually not an experiment. Laughing became a laughter, and many people hurt.
Niu Xin sprayed a few times with a spray lamp, and the alcohol lamp was still unable to order. It was so burnt on the side of the big cake. I couldn't help but say, "Professor Fei, why not do this directly to do this. Big cake! Isn't it all fire? "
Fei Chai came out of the hiding, took over the lamps, and after turning it off, it took it to say, "The idea of classmates Niu is actually very good, but when a method does not work, you may find a new one to think about it. The path to success is just this is not today's theme. Today's theme is the energy gradually interpreted. "He said, thanking the students participating in the experiment, and then asked them to return to their seats, and then to everyone Say: "Students, although the two students were not able to order the alcohol light today, the experiment was really successful." He said, seeing everyone's confusion, and smiled and took the big cake from the grill. Come down, and then throw it aside and say, "Actually, I just joked with everyone. This big cake has nothing to do with the half dime of the crust. It is more important. It is this kind of liquid in the alcohol lamp. Everyone knows that this liquid is in the end What is it? "
Everyone looked at each other, I didn't know how to answer, Fei Chai waited enough time, pulled out the core with a smile, and sipped it in the mouth of the bottle, and then laughed: "In fact, this is the ordinary bottled water, everything I did just now, everything I did just now did , But it's all mysterious. "
Everyone was relieved, but then I wanted to know why Fei Chai did this. Fei Chai pointed at the alcohol lamp and said, "This is just ordinary bottled water, can you really understand its characteristics? To put it bluntly, water can carry boats, and it is said that people will cause dehydration and death without drinking water for three days. But if it falls into the river to drink too much? Will it drown?
Everyone nodded and said yes.
Fei Chai also said: "This is the two sides of the water, there is no no, too much, and there are two aspects of all things in the world. Even the scientific principles are the same. One of them, the inner corner of the triangle is one hundred and eighty degrees. This is the truth, but if we put this truth in the three -dimensional geometry, is this still the truth? If it is a convex triangle, then the sum of its inner angle must be greater than one hundred hundreds of hundreds. Eighty degrees, if the sum of the inner corner of the concave surface triangle must be less than 180 degrees, so students, we are now studying in higher education institutions. First of all In addition, we need to remind everyone. We are engaged in scientific research, science, and prove that true and false, not good and evil, so because people are nonsense, we must not appear in our study and research. Because in the long river of history, we have suffered too much of the loss here, not to mention that the energy is gradually explained, nor was it discovered by Professor Qin Zhong! Oh, if that, Professor Qin is already hundreds of years old older old -fashioned old -fashioned old -fashioned old The fairy is. "Everyone listened, and smiled at themselves.
Fei Chai is almost the same as everyone laughs, and then use gestures to show the quiet family's quietness, and then say "Okay, now I will tell you the basic principles of energy gradually interpretation from the perspective of geology ... In addition Rigid things, everyone pays attention in the future, I never jokes when I do experiment. If you are joking, you must not do experiments. "
At this point, Zhang Qi's heart finally settled a stone, and Fei Chai had passed another level.
