The Day of the Draw at Hogwarts

To be precise, this is not a qualified "Finnish wood stove" because the wood is too fresh.

Fresh wood contains a lot of moisture, which can make it difficult to ignite and cause unnecessary smoke. But difficulty is relative. Wood cannot be ignited just because it is not dry - otherwise, how would those wildfires expand? The trees burned by wildfires are all fresh trees.

Tom's match suddenly ignited the dead branches and leaves stuffed into the core of the tree, and a wisp of smoke came out from the assembled stump.

"It's burning, it's burning!" Mr. Weasley danced excitedly like a child. For him, making fire the Muggle way was still his first experience in life.

He took Tom's matchbox into his hand and said, "I'll try it too!"

However, like many children who are exposed to matches for the first time, Mr. Weasley cannot strike a match. He was also a little confused: Tom had succeeded with just one stroke, but when it was his turn, he couldn't do it no matter how hard he stroked.

Each match was broken in his hand, or the igniting material in the front part was worn away, and the sandpaper on the side of the matchbox was also completely worn away.

Mr. Weasley let out a long sigh.

Tom came over and threw the scattered matches on the floor into the wood stove, fanning the fire.

At this time, Mr. Weasley finally struck a match, but the sudden flame startled him, and he threw the match to the ground.

Onlookers:...

Fred couldn't help but cover his face with his hands.

"The sandpaper in this box is no longer useful," Hermione said gently, taking the matchbox from Mr. Weasley and showing him what to do.

"She will be very good at taking care of children in the future." George listened to Hermione's patient explanation and made a judgment.

Under Hermione's guidance, Mr. Weasley finally learned how to strike a match. He kept striking the match and then dropped it into Tom's pile.

At this time, the inside of the wooden pile had been ignited, and the smoke coming out was so thick that people could not open their eyes.

The principle of this wood stove is to let the kindling material ignite the core of the wood pile, and then carbonize bit by bit to form a carbon fire that keeps burning. This smoldering method can effectively extend the burning time of the wood. In the end, a large hole similar to a triangle will be burned into the pile.

"Ahem...the fire has been lit." Tom stepped away from the wood stove.

"The Finns will insert a Z-shaped pipe into this cavity." Tom gestured towards the fireplace, "One end will be connected to the outside of the wood stove, and the other end will be connected to the tent, so that the cold air from outside will pass through the wood stove. It will be heated and turned into hot gas, which is the heating principle of Finnish wood stove."

Mr. Weasley nodded repeatedly, and he now understood how Muggles without magic could survive in the ice and snow.

"It should be noted that the air inlet of the pipe must be outside the wood stove..." Tom began to spread some safety knowledge. Because Tom is not sure whether wizards have the concept of carbon monoxide poisoning - he feels that they do. There are ventilation measures behind every fireplace in Hogwarts, so it will not cause a tragedy like suffocating an academy student to death in one winter night.

"So that's it! Tom, you are so knowledgeable!" Mr. Weasley was excited, feeling that he had learned so much knowledge that he didn't know when he would use it. He patted Tom on the shoulder, "Merlin! Where did you learn these things?"

"Well, these are all Muggle common sense." Under the strange eyes of the Grangers, Tom replied, "After you understand Muggle science, you will know many unreasonable things, such as ice and snow The temperature inside a house is actually not too low. For example, the 'gas' you see after boiling the kettle is not actually gas."

Looking at the Weasleys around him who looked like they were in advanced math class, Tom knew that they didn't listen. There was nothing Tom could do about it. Who told wizards to only take magic classes since childhood? There is no mathematics and physics in the world of most wizards. They are unable to understand various physical principles at all, their logical thinking is poor, and their understanding of the nature of the world is shallow.

The solution might be to set up a mandatory general education class at Hogwarts, right? Teach students some simple physical and chemical knowledge. As for mathematical calculations, this skill can be supplemented by arithmetic divination. In the process of arithmetic divination, a large number of calculations will be involved. By mistake, the wizards were given math lessons.

General courses do not expect to train wizards into scientists who can carry out academic research, but only to prevent them from being too ignorant.

At this time, a large amount of smoke no longer came out of the wood stove, and a clump of flames emerged from it. This clump of flames announced that the stove was successfully ignited.

After a while, Harry and the others also came back carrying the kettle. Tom put the kettle directly on the wood stove to boil water for tea.

The process of waiting for the water to boil was not boring. Their tent was located on the road leading to the stadium, and there were many officials from the Ministry of Magic running along the road. Mr. Weasley is very popular in the Ministry of Magic. Many officials from the Ministry of Magic will stop and say hello when they pass by. Mr. Weasley also keeps introducing everyone, allowing these officials to interact with Tom, Harry, and Hermione and others got to know each other.

This is the hidden asset of a pure-blood family. Even though the Weasley family is too poor to afford textbooks, they are still an ancient pure-blood family active in the middle and lower classes of the Ministry of Magic.

Director of the Goblin Liaison Office, staff of the Experimental Spells Committee, memory cancellers, mute people... Tom got to know the staff of the Ministry of Magic one after another.

The water was boiling, and Mr. Weasley made a pot of tea, a pot of porridge, fried a lot of eggs, and hung sausages on skewers and roasted them in the wood stove - this roasting method is called exquisite, and the fat on the top of the sausages is baked It will slide vertically down the sausage, soaking other parts along the way. In the end, the sausage was obviously grilled, but it had a fried texture. In addition to sausages, bake potatoes to make the most of every ounce of heat and fat.

The fatigue of walking in the early morning was swept away.

With a bunch of grilled sausages in one hand and a bowl of porridge in the other, Tom ran over to Fred and George and sat down cross-legged.

"This place is full of wizards."

"Yeah." Fred was slicing the cooked sausage and sandwiching it between two slices of eggs.

"They are all potential customers." Tom took a big bite of sausage.

"We know, but all our Fat Tongue Toffees have been confiscated." George grimaced and drank the porridge one after another. The vegetable rice porridge was so bitter that he drank it.

"I didn't recommend that you sell fat tongue taffy here - think about it, there are so many children here, and their parents will kill you if you eat them by mistake." Tom shook his head, looking confident.
