2864 - - 76-11 The Science Room and...

"Now, the next room is the .

Jin led the guests to the east room.

"Oh, this is ......."

While the previous rooms had been related to magical engineering, this room displayed materials related to pure <.

"In particular, it explains the science used in the magical tools and machines created by the <."

"This is interesting."

"This is interesting."

......, but it may be difficult to fully understand it without a minimum of scientific knowledge."

"Yes, that makes sense."

"First of all, there is the pump. You can see in the model how the valves work to pump the water.

"Oh, ......"

A one-half scale model of a pump made of transparent material is placed on the floor, and when the handle is moved up and down, water can actually be pumped out of the water tank at the bottom.

As you do so, you can see how the two valves inside the pump work.

"This is interesting."

Niestor Cirillo Jagus, Prince of Jagus, is excited as he moves the handle up and down.

"This is the principle of a microscope.

A convex lens is set up to show how it collects light.

A parallel beam of light passing through a slit and coming together at the focal point through a convex lens is shown, with a pictorial explanation.

"...... I see, I wonder if the principle of collecting heat or light used by <> is similar."

Again, the Duke of Jagusu was the most interested.

"What is this, Jin-dono?

asked Citranella de Zaus Firenziano, the Undersecretary of the Ministry of Magic and Technology of the Kingdom of Elias.

He is a direct descendant of the Marquis de Firenziano, the man who created the <> together with Jin and Reinhardt.

"It is the principle of <>.

It explains how seawater can be distilled to produce fresh water.

The boiling point was explained as the basis of this process.

"I see.

"So water and salt have very different boiling points, which is why they can be separated in this way.

"...... Yeah?　That means ...... Jin-dono, isn't it possible that such a separation may not be possible when the boiling points are close to each other?"

Kouki Katou, Mitsuho's technical manager, asked a rather pointed question.

"That's right. Take, for example, a mixture of water and ethanol. The boiling point of water is 100 degrees Celsius, and ethanol is ......."

It's about 78.4 degrees, father.

"Thank you, Reiko."

Since Jin did not immediately come up with the boiling point of ethanol, the old man and Reiko quickly followed up.

As you heard, the boiling point of ethanol is 78.4 degrees Celsius, which is quite close to the boiling point of water. Therefore, it would take a lot of time and effort to separate only ethanol from a mixture of water and ethanol.

"I see, that's true."

The most familiar mixture of water and ethanol is sake.

Freshly brewed sake contains a lot of water, so it is sometimes distilled to raise the alcohol (ethanol) content (and also to eliminate impurities), but pure ethanol cannot be separated in this process.

In fact, it is not possible to distill alcohol (spiritus) with an ethanol content of more than 96%.

This is called an .

To get 100 percent ethanol from this, you have to do something other than distillation.

"Hmmm, that's difficult."

"I think it was written in the technical book left behind by the Wise Master Mags," he said.

"Yes, it might have been ....... No, I don't want to take up any more of your time. Thank you very much, Mr. Jin.

Other exhibits and explanations included (how ships float on water and balloons float in the sky), , and .

Jin was pleased to see that all the invited guests were interested in the exhibits.

Next room.

We moved to the exhibition room located in the southeast.

"This room displays ...... replicas of historical tools, magical tools, and magical machines other than <>.

"Oh!"

This is quite something!"

The first thing that caught my attention was the <> and <> on display in the center of the room.

"This is a replica of the <> made by >, a of the Shoro Empire of the same generation as the <>."

"Yes, it played an active role together with Miss Reiko at the held in our country, didn't it?"

The one who said this was, of course, Ernest XVII, the third prince of the Kingdom of Egelea.

"Yes. And this is a replica of the crystal golem <>...... by Stearina Gamma, the Magi Craftsman of the Kingdom of Celuloa, which was presented at the ."

"This is beautiful."

"It's made of crystal, isn't it? It must be very difficult to control."

"It would be wonderful if it could move."

The two pieces were well received. Jin was pleased inside that it was worth displaying them in the center of the room.

"This is a model of a huge ship that Mr. Eckart Tecles, a wealthy merchant of the Kingdom of Cerroa, sold his personal fortune to build.

"Oh, ......."

"......Hmm, the king of the time took him away and Mr. Tecles went into exile in the Kingdom of Shoro and became an economic advisor. ......"

"What, did Mr. Tecles like cats so much that he had several?"

"It was an interesting way of propulsion at the time to use wind magic ...... against the sails."

"This is the same idea as the blow floaters."

"You were a man of flexible ideas, weren't you?

Jin did not want the name of Eckart Tekres to be buried in history.

"And then ......"

"Oh!　Our country's <, isn't it?

"Yes. <

That is the legend, isn't it?

These are household items.

"Oh, is this from ......<>?"

Yes, displayed here are a variety of tools and magic tools made by Bina.

"I heard that the concept was to make things that would be useful in the daily lives of the common people.

"Yes, the pride of our Egelea Kingdom."

Jin realized that these exhibits would also be eye-catching and serve as a beacon of technology to be passed on to future generations.
