Rooster and Fireworks

Before leaving the Headmaster's office, Anthony emphasized to Dumbledore that there might be a basilisk in the castle.

"Thank you, Henry," said Dumbledore, "I'll keep an eye on it."

Anthony didn't know how he was going to pay attention to this, but the next day he heard that Hagrid was carrying two roosters around Hogwarts.

Hagrid held the two poor creatures in his hands and waved them around, making them crow like a bell. The chicken feathers flew everywhere and scattered all over the floor.

Filch was furious, but Dumbledore said: "I asked Hagrid to do it. And the students are happy about it, aren't they?"

The students were very curious and followed Hagrid in the Hogwarts Parade. Peeves took the opportunity to stick feathers all over Mrs. Norris's body, and disappeared giggling amidst Filch's curses. ("Cat-headed chicken, haha!")

The Weasley brothers pulled out a whistle from somewhere and blew the command as they marched behind Hagrid. Students who can whistle follow their rhythm, and some also learn a few rooster crows from time to time. The castle's ancient vaulted cloisters echoed with cockcrows and whistles.

Hagrid puffed out his chest and tried to drive them away, saying that he was doing something for Dumbledore. Harry asked him what it was, and Hagrid waved his cock roughly: "Stop asking, Harry!"

"It's a secret again, isn't it?" Harry Potter brushed the chicken feathers off his head and asked, "I don't understand, if this is a secret, why don't you do it at night? Now the whole school is following you. "

Hagrid was stunned. He hadn't thought about this problem.

…

The students came later than usual when Anthony was in class, and they all went to watch Hagrid flick his cock.

"Sorry, Professor." Cedric was slightly out of breath from running, and this recognized good student also went over to join in the fun.

"It's okay, sit down." Anthony didn't care. "If I hadn't gotten up late, I wouldn't have missed this excitement."

After returning home last night, he spent some time thinking about his resurrection. It wasn't until the stars and moon faded and the sky turned slightly white that he remembered that he had classes the next day.

Seeing that everyone had arrived, he closed the door and announced the start of class.

"Does anyone recognize what this is?" He waved his wand and unfolded a hanging painting in front of the blackboard. Against the huge dark background is a gray-white desolate scene.

"Azkaban?" someone guessed.

"Nurmengard?"

"I recognize it," said a student sitting in the back row. "It's the moon."

Several people couldn't help laughing, and Anthony also laughed: "Who said that? Ah, very good, two points for Ravenclaw."

The laughter disappeared. The students looked at the picture carefully, trying to find the slightest resemblance to the moon.

Anthony said: "In this class we talk about the night sky under the feet of Muggles. Yes, this is the moon. Muggles went to the moon, took this photo, and left a famous footprint on the moon." He told They showed the footprint and said, "Does anyone know how they did that?"

"Build a long ladder?" one student suggested in a low voice.

"Superimposed on Muggle metal brooms?" another student guessed.

They had accepted that Muggles would use some tools to achieve the effects of spells, so they created a word formation: adding the word "Muggle" in front of magic to refer to Muggle tools that achieve similar effects. An airplane, for example, is a "large Muggle enclosed metal broom".

"Hmm...kind of close?" Anthony said, "But that answer is too general. My answer would probably be combustion and interaction."

This lesson was improvised after he returned from the Forbidden Forest. The centaurs' obsession with the stars gave him some inspiration... He decided to use rockets as an entry point to talk to the students about the power of combustion.

Although airplanes have been talked about before, for students who are already avid Quidditch enthusiasts, flying in the sky is not an exciting story.

In addition, Anthony's lectures at that time mainly focused on Muggle travel methods, and did not explain aerodynamics and other principles to them in detail - he was training wizards who understood Muggle life, not physicists. Muggle physics just doesn't work in the wizarding world.

In this completely idealistic world, physics is as messy as a ball of wool under a cat's paws. The conservation of mass and energy do not exist in the eyes of magic. Students have a hard time understanding why combustion produces propulsion—if you want something to move, all you need to do is command it to move correctly.

So this time, Anthony spent most of the class talking to them about the physical world from the eyes of Muggles.

Even though he blew up several balloons, the students who watched them whining and running around the room still couldn't understand.

In the end, Anthony almost forced them to remember that there is something called "interaction", just like the transfiguration technique that forced him to imagine that the mouse in front of him was a rubber.

He used magic to demonstrate to his students the power of combustion and explosions. After getting them to understand what a thruster is, he spent some time talking about the importance of weight reduction.

"In a world without magic, if you want to fly, you have to fight gravity. Have you noticed that owls are much lighter than cats of the same size?"

The student nodded.

"They give up a lot of weight to be able to fly," Anthony said. "Their bones, their digestive system... but that's another story. What I'm saying is, like birds, in order to allow this big thing to fly To get to the moon, it has to be light enough."

"But professor, the dragon is not light at all?" the student questioned.

"Yes, but what do dragons have more than Muggles?" Anthony said.

"...wing?"

Anthony smiled and shook his head: "Magic. Classmates, the reason why Muggles' current achievements are amazing is precisely because they do not have the magic to make everything they want come true."

He pointed to the blackboard and balloons: "All of these are based on a set of rules they have developed themselves. These rules do not change based on people's likes and dislikes. Just like playing chess, they can only move the pieces within the rules, but Look at this picture." He gestured to the picture of the moon.

At the end of the lesson, he took them to the window to watch the fireworks being lit downstairs. Professor McGonagall looked strange when approving his purchase request, with an additional warning not to sell fireworks to students - Anthony thought she was referring to the Weasley brothers.

Fireworks flew to the window and exploded in front of the entire class. In the shadow of the castle, these close-up colorful fires are beautiful even during the day.

"First there are feathers, and then there are fireworks." The classmate muttered, "Today is really like a carnival."

"Explosion and interaction, students." Anthony said, "The force that makes fireworks fly to us is the same force that makes people go to the moon."

"Muggles put themselves on top of a big firework?" the student asked in amazement.

Anthony thought for a while and smiled: "That's pretty much it. After all, the first attempt by humans to fly was to make their own chairs into big fireworks and then blow them up."
