Farm Gate Escape: There is Room For Full-level Bosses

   Chapter 444 See another magical world

   Kitten got the same experimental utensils as Bai Wutong.

  White phoenix tree as a demonstration, put a magnet in the middle of the coil, the magnet is a strong magnet, and the center of the coil is hollow, so that the magnet can move left and right freely.

  Bai Wutong picked up the small wick again and smiled: "The key point of the game is here, see clearly. Connect the two legs of the wick to the two wires of the coil, and press down with your left hand to prevent them from loosening."

   Her movements are very slow, the kitten quickly catches up with her rhythm, and the completion is exactly the same.

   Bai Wutong praised: "Our kitten is doing really well."

  The kitten's ears are slightly red, looking forward to the next step.

   Bai Wutong smiled: "Now is the time to witness the miracle."

  Bai Wutong pressed both ends of the coil with his right hand to block the magnets inside from falling out. It shook vigorously in the direction of the round hole, and the magnets went back and forth freely in the coil.

  Suddenly, the little wick lit up.

  The kitten's eyes suddenly widened, her face full of wonder.

  He Jinchuan used such a complicated circuit board to light up the wick, and Bai Wutong only used coils, magnets, and a few simple operations to do it.

   is really incredible.

  The kitten looks sluggish and cute.

Bai Wutong smiled softly: "Is it magical? This game is based on the electromagnetic induction principle of a generator. The magnet you hold in your hand passes through the closed coil, and each coil and magnet will generate an invisible voltage invisibly. The more turns in the coil, the higher the voltage and the brighter the wick."

  The kitten was still digesting slowly, Bai Wutong instructed: "You also try it."

   His memory is very good, the kitten recalled the operation of Bai Wutong just now, and after a while, the wick also lit up.

   This light seemed to open his heart and his world completely.

   He exclaimed in surprise like a real child, "It's bright, it's bright!"

  Bai Wutong touched his head, "Well, it's great."

   "In addition, the stronger the magnet's attraction, the stronger the electricity generated, and the brighter the light bulb."

   Kitten knew that Bai Wutong was teaching himself patiently, he nodded excitedly, and carved every sentence into his bones, which he will never forget.

   In addition to letting the kitten know how the generator is produced, Bai Wutong also asked people to find two potatoes and two freshly ripe lemons.

   Kitten picked up the potatoes excitedly, he knew that Bai Wutong would definitely teach him something more interesting.

  In addition to potatoes and lemons, White Indus also prepared wires, zinc sheets, and copper sheets.

  Bai Wutong cut the potato into four pieces and said with a smile, "There are many principles for generating electricity. Believe it or not, you can also generate electricity with potatoes?"

  The kitten nodded without hesitation, Bai Wutong let out a low laugh, and then inserted a piece of copper and a piece of zinc into each piece of potato.

   Connect the two ends of a wire to a piece of potato's zinc sheet and copper sheet, and so on, and connect them in an orderly manner.

   Finally, connect one end of the other two wires to the remaining copper and zinc sheets, and connect the other end to the wick.

  Before the contact, Bai Wutong smiled mysteriously, "The time to witness the miracle has come again."

  The kitten's eyes widened, and the "swoosh" wick came on!

  White Indus really did it!

   This interesting experiment was learned in Bai Wutong’s junior high school. At that time, it was taken for granted, but the kitten seemed to have seen a miracle, and looked at her with admiration and piety in her eyes.

   was shocked for a while before the kitten asked, "Why can potatoes also generate electricity?"

Bai Wutong explained: "Because potatoes have an acidic substance that can be used as an electrolyte, zinc and copper have positive and negative poles. After they combine with each other, they will react to form an electric current. With electricity, the wick will It's lit."

   Kitten was amazed, and couldn't help but ask: "How do you know that the acidic substances in potatoes can be used as electrolytes? Potatoes aren't sour, aren't they?"

Bai Wutong couldn’t say that it was written in a book. The teacher asked them to memorize it and explained: “It is actually very simple to judge whether there are acidic substances in the food. Just burn the food into ashes, and finally see if they dissolve in water. The results can be obtained, generally soluble in water is acidic, insoluble in water is alkaline.”

The kitten just realized, Bai Wutong added: "Acid food is not necessarily acidic, the most important thing is to judge the ingredients in it. Westerners have an instrument that can detect the ingredients in the food. According to the ingredient list, it will also be detailed. The division of strong acidity, acidity, weak acidity, alkalinity, etc., is used for the study of food and medicinal materials.”

   Kitten was very surprised, "What kind of instrument is so powerful?"

   Bai Wutong smiled and said, "Have you seen the glass glasses that gentlemen are wearing now?"

   "Well, I've also worn it!" He was quite proud, and his eyes were full of light.

   "Westerners' instruments are constructed with lenses. It is said that as long as you cut a small piece of food and put it under the lens, you can see another magical world."

   Bai Wutong's knowledge is so extensive, the kitten is very fascinated.

  White Indus cut the lemon again, "Try it? Let's see if a sour lemon can generate electricity."

   Kitten took the lemon and nodded heavily, "Yeah."

   After a while, repeating the same wiring steps as the potato, the wick suddenly lit up.

   Kitten said excitedly: "Lemon contains acidic substances, it can generate electricity!"

  Bai Wutong smiled happily: "Well, what I want to tell you today is that there are many ways for everything in the world to generate electricity, as long as you master the laws, you can do it."

"Electricity is very dangerous, but it can also bring infinite power. If it is used properly, it can be applied to our lives. For example, the weak wick in front of us can illuminate the entire night sky and form a bright light. underground galaxy."

   Kitten felt the painstaking guidance of Bai Wutong, and nodded firmly, "I will definitely go back to study and try to make a more convenient fan by next summer."

   Bai Wutong smiled and said, "It's good for you to have goals, but you should also pay attention to your body. If you don't understand anything, you can go to the scientific research room for advice, and I'll give you a pass."

   Kitten didn't expect Bai Wutong to do this for him, her eyes flushed red, she knelt down and kowtowed heavily, "Thank you, Empress!"

Bai Wutong let the breeze help him, and said: "The spray fan you are making now is also very good, the cost is not high, and it is placed outdoors for everyone to enjoy the cool, and it is also an attractive and unique scenery, presumably, everyone will be eager to buy it first. production rights."

   Kitten quickly said: "I have already dedicated it to you, so I won't sell the patent rights."

Bai Wutong smiled and said: "Silly boy, if everyone gave like you did, everyone would think, if they have created something good, should they also give it away? I have already received your share. I like it very much, and I will put it in the yard in the future."

   "I'm a little tired, let's register with Mr. Shan."

   Kitten nodded obediently, and said very firmly: "Empress, I will definitely let you use a better fan next year!"
