Chapter 445: Seeing Another Magical World
Translator: Atlas Studios Editor: Atlas Studios
Little Cat held the same experimental equipment as Bai Wutong.
Bai Wutong demonstrated and placed the magnet in the middle of the coil. The magnet was a powerful magnet, and the center of the coil was hollow. This way, the magnet could move freely left and right.
Bai Wutong picked up the small wick again and smiled. “We’ve arrived at the key point of the game. Look carefully. Connect the two ends of the wick to the two threads of the coil and press down with your left hand to prevent them from loosening.”
Her movements were very slow. Little Cat quickly followed her and completed it exactly.
Bai Wutong praised, “Our Little Cat is really good at it.”
Little Cat’s ears turned red as he looked forward to the next step.
Bai Wutong smiled and said, “Now is the time to witness a miracle.”
Bai Wutong pressed both ends of the coil with her right hand, blocking the magnet inside and preventing it from falling out. She shook it hard in the direction of the round hole, and the magnet moved back and forth freely in the coil.
Suddenly, the small wick lit up.
Little Cat’s eyes widened in disbelief.
He Jinchuan had to use such a complicated circuit board to light the wick. Bai Wutong only used a coil and a magnet to do it.
It was really unbelievable.
Little Cat’s dazed appearance was quite cute.
Bai Wutong smiled gently and said, “Is it magical? This game is the electromagnetic induction principle of a generator. The magnet in your hand pa.s.ses through the closed coils. Every coil and magnet will produce an invisible voltage. The more coils there are, the higher the voltage and the brighter the wick.”
Little Cat was still slowly digesting it when Bai Wutong instructed, “Try it too.”
His memory was very good. Little Cat recalled Bai Wutong’s movements just now. Not long after, the wick lit up.
The light seemed to have opened the door to his heart and his world completely.
He shouted in surprise like a real child. “It’s lit up, it’s lit up!”
Bai Wutong stroked his head. “Yes, you did well.”
“In addition, the stronger the magnet, the stronger the electricity generated, and the brighter the bulb.”
Little Cat knew that Bai Wutong was patiently teaching him. He nodded excitedly and engraved every word into his bones. It was unforgettable.
Apart from letting Little Cat know the principle of producing a generator, Bai Wutong got someone to find two potatoes and two freshly ripe lemons.
Little Cat picked up the potatoes excitedly. He knew that Bai Wutong would definitely teach him some more interesting knowledge.
Apart from potatoes and lemons, Bai Wutong also prepared wires, zinc, and copper.
Bai Wutong cut the potatoes into four pieces and smiled. “There are many principles for electricity generation. Do you believe that potatoes can also generate electricity?”
Little Cat nodded without hesitation. Bai Wutong chuckled and inserted a copper piece and a zinc piece into each potato.
The ends of a wire were connected to the zinc and copper slices of a potato respectively, and so on.
Finally, she connected one end of the other two wires to the remaining copper and zinc pieces and the other end to the wick.
Before they made contact, Bai Wutong smiled mysteriously. “It’s time to witness a miracle again.”
Little Cat widened his eyes. The wick lit up with a whoosh!
Bai Wutong had indeed done it!
Bai Wutong had learned this interesting experiment in junior high school. At that time, she thought it was only natural, but Little Cat seemed to have seen a miracle and looked at her with incomparable admiration.
After being shocked for a while, Little Cat asked, “Why can potatoes also generate electricity?”
Bai Wutong explained, “Because there’s an acidic substance in potatoes that can be used as an electrolyte. The zinc and copper slices act as positive and negative polar ends. After they are connected, they will react and form an electric current. With electricity, the wick will light up.”
Little Cat was extremely surprised and couldn’t help but ask, “Then how do you know that the acid in potatoes can be used as an electrolyte? The potatoes aren’t sour either?”
Bai Wutong couldn’t possibly say that it was written in a book and that their teacher had asked them to memorize it. She explained, “It’s actually very simple to determine if there’s any acid in food. As long as you burn the food to ashes and see if it’s soluble in water, you can get the results. Usually, solubilizing in water is acidic, and insoluble in water is alkaline.”
As soon as Little Cat came to a realization, Bai Wutong added, “An acidic food might not necessarily be acidic. The most important thing is to judge the ingredients. The Westerners have an instrument that can detect the ingredients inside the food. According to the ingredient table, it will also be divided into strong acidity, weak acidity, alkaline, and so on for research on food and herbs.”
Little Cat was extremely surprised. “What kind of instrument is so powerful?”
Bai Wutong smiled and said, “You’ve seen the gla.s.ses the teachers are wearing now, right?”
“Yes, yes, I’ve even worn it before!” He was rather smug, his eyes filled with light.
“The Westerners’ equipment is made of lenses. It’s said that as long as you cut off a small piece of food and place it under the lenses, you can see another magical world.”
Bai Wutong was so knowledgeable that Little Cat was extremely fascinated.
Bai Wutong cut open the lemon again. “Do you want to try it? Let’s see if the sour lemon can generate electricity.”
Little Cat took the lemon and nodded heavily. “Yes.”
After a while, the wick suddenly lit up after repeating the same circuit connection steps as the potatoes.
Little Cat said excitedly, “Lemons contain acid. It can generate electricity!”
Bai Wutong smiled in relief and said, “Yes, what I wanted to tell you today is that there are many ways for everything in the world to generate electricity. As long as you master the principle, you can do it.”
“Electricity is very dangerous, but it can also bring endless power. If used appropriately, it can be used in our lives. For example, the weak wick in front of us can illuminate the entire night sky and form a dazzling galaxy.”
Little Cat sensed Bai Wutong’s painstaking guidance and nodded firmly. “I’ll definitely go back and study it carefully. I’ll strive to create a more convenient fan before next summer.”
Bai Wutong smiled and said, “It’s good that you have a goal, but you have to take care of your body. If there’s anything you don’t understand, you can go to the research lab to ask for guidance. I’ll give you a pa.s.s.”
Little Cat did not expect Bai Wutong to do this for him. His eyes suddenly turned red as he knelt down and kowtowed heavily. “Thank you, Great Empress!”
Bai Wutong asked Qingfeng to help him up and said, “The spray fan you’re making now is also not bad. The cost is not high. If it’s placed outside for everyone to enjoy the shade, it will also be a unique scenery. I believe everyone will also fight to buy the production rights.”
Little Cat hurriedly said, “I’ve already given it to you, so I won’t sell the patent.”
Bai Wutong smiled and said, “Silly child, if everyone offers up something like you, everyone will wonder if they have to offer it up after creating it. I’ve already received your share. I like it very much. I’ll put it in the courtyard in the future.”
“I’m a little tired. You can follow Lord Sheng to register it.”
Little Cat nodded obediently and said firmly, “Great Empress, I will definitely let you use a better fan next year!”
