"Wow--"

Seeing this scene, Winnie shouted in surprise: "Water, water is coming out!"

Owen tightened the faucet and closed it, then turned around and announced happily: "From now on, the castle has entered the running water era, and we can say goodbye to the days of drawing water from the well."

"Oh - it's amazing."

Weiru folded his arms and couldn't help but nodded, and suddenly said: "I finally understand why the apartments that the Marquis asked me to build have some holes reserved, all for laying these water pipes."

"You're not entirely right." Owen shook his head slightly, "The water system is just one of them, there are other systems that require reserved holes."

"oh?"

Hearing this, Weilu's eyes lit up and he immediately became interested and asked: "What other systems are you planning to install?"

"Heating system and power supply system." Owen replied, "But we still need to make corresponding modifications to the castle first and accumulate some experience. The apartment cannot be installed so quickly."

"It's really exciting." Weiru said.

"Where does the water come from? Is there any magic in it?"

On the other side, Winnie curiously came over and turned the faucet lightly. Water gushes out again. She was so frightened that she quickly stretched out her hand to hold it underneath.

"Can this water be drunk directly?"

Staring at the water in her hand, Winnie almost brought it to her mouth and drank it.

"no!"

Fortunately, Yuqina stopped her in time and explained: "The teacher said that there are many unclean things in the water, and it must be boiled before drinking, otherwise it may cause diarrhea."

Since Yuqina knows how to stop Winnie, it means that the school's health education work is doing a good job.

Coupled with the City Hall's vigorous promotion of the importance of hygiene, people's hygiene habits in the town are gradually changing for the better.

"Eh?" Winnie looked confused, "The water is obviously very clear. Is there anything unclean there?"

"this……"

Yuqina stretched out her hand and scratched her head, and thought for a while before she said, "The teacher seems to have said that the unclean things are invisible to the naked eye."

"Can't see?"

Winnie frowned and looked down at the water in her hand, still unwilling to throw it away.

"Yukina is right."

At this time, Teresa came over and tightened the faucet again.

"There are many bacteria invisible to the naked eye in natural water. They must be boiled to kill them before you can drink it. Otherwise, drinking too much will cause diarrhea. However, the water produced by magic can be drank directly. It is very pure."

"Isn't this water produced by magic?" Winnie asked again.

"It's not true."

In response, Teresa showed a gentle smile and explained kindly: "Isn't there a very tall water tower built in the backyard of the castle? The top is actually a large water tank, and then the steam engine below pumps the water from the well to the large water tank.

inside……"

"Ah! I understand."

While the other party was speaking, Mapel suddenly interjected: "Water will only flow downwards. The big water tank is higher than this floor, so the water will flow here along the pipes, isn't it?

"

After finishing speaking, she showed a proud expression on her face, as if she was waiting for everyone's appreciation, especially the verbal praise from Owen.

"Oh - that's it."

Winnie looked like she was suddenly enlightened and nodded.

Then, she released her hands and let the water fall into the wash basin below, and then drained out along the drainage pipe.

"Sister Mapel, you are so smart!" Yuqina also agreed with Mapel's explanation.

"Uh...this..."

Seeing that Mapel was so confident, Theresa was a little embarrassed and couldn't bear to expose this mistake.

But as a teacher, she must correct mistakes when she finds them.

"What you said is not quite right."

"Eh? Isn't that right?" Mapel was startled.

Winnie and Yuqina were also confused. Wasn't the explanation just now very good?

"well--"

Irving on the side held his forehead and sighed, and couldn't help but intervene: "Mapelle, your explanation is not thorough enough and you didn't get to the point."

It has to be said that Mapel is an empiricist, and all explanations will be based on his own experience. This was also the case when he explained why the boat floated.

Obviously Owen had given her many lessons, but in the end, all the theoretical knowledge he taught was useless.

It can only be said that Mapel did not fully understand the theoretical knowledge, he just memorized it.

"It's not enough to just use the principle of 'water flows to lower places'. How do you explain this paragraph?"

Owen pointed to the end of the water supply copper pipe on the ground, the short section connected to the faucet.

"You see, the water comes from here, but it has to go up before it can come out from the faucet. You definitely can't explain this part of transporting water upwards as 'water flows down'.

Bar?"

"It really can't be..."

Looking at that piece of water pipe, Mapel couldn't help but lower her head, her cheeks and ears were red and hot.

Ah! How embarrassing! I really want to find a crack in the ground and crawl in.

Fortunately, she thought her explanation was correct, so she couldn't hold her head up now.

"Well, well."

At this time, Teresa stood up, clapped her hands to attract everyone's attention, and gave a correct explanation.

"The reason why the faucet can discharge water involves the siphon principle, which refers to the force phenomenon that uses the difference in liquid level. For example, two containers are at different heights and are connected through a pipe. No matter what shape the pipe is, the container with the higher position

The liquid inside will be transported to the lower container, and the flow will not stop until the liquid levels of the two containers become the same height."

After explaining, Gita and Vilu fell into deep thought and looked thoughtful.

Yuqina was confused and couldn't understand it at all.

Winnie simply shook her head and said with a painful look on her face: "I don't understand. I can only understand Marpel's explanation."

"Winnie, I think you need to go to school and study hard." Owen suggested, "Flight training can be done after school. If you have a mission, take time off."

It’s time for this winged tribe from the Storm Islands to study hard. Understanding human writing will also help in performing tasks.

"OK!"

Winnie does not hate school, but is looking forward to it.

"Can I be in the same class as Yukina?"

During the chat before going to bed every night, Yukina would tell Winnie about what happened in school.

Therefore, Winnie still knew that the school divided classes according to age groups.

"Well..." Owen touched his chin, "Given your age, you were supposed to go to the adult class, but the adult class is a night class. If you don't mind the strange looks from the students around you, I can arrange it.

You and Yuqina are in the same class."

Anyway, the main purpose is to learn writing, so you can take Yuqina’s class.

"Then it's settled!"

Winnie excitedly flapped her wings behind her, and then squatted down in front of Yuqina.

"Did you hear that? Yukina, I can be in the same class as you!"
Chapter completed!
