At this time, Hendry looked embarrassed, although he wanted to fight back, but he didn't know how to challenge Su Huai, but to his surprise, Yelev stood up and said:

"Mr. Su, you Huaxia people can come up with the idea of using gunpowder as a means of epidemic prevention, it is indeed worthy of admiration, according to common sense, our World Academy of Sciences should affirm your contribution, and also have a batch of funds, so that your Huaxia Academy can study this project.

But science can't rely on a little circumstantial evidence, and setting off firecrackers is not a tradition of your Chinese country in the final analysis, and the age of birth is impossible to study, based on this alone, I will not admit that you invented gunpowder in China.

If you say I'm being a strong word, I have nothing to say, but I have to express it. ”

When everyone in Huaxia heard this, they all thought: "The same scholar, this bearded Yelev is much more upright, knowing that now that Mr. Su has the upper hand, he still fights on the basis of reason, which is much better than a fame and fortune villain like Hendry." ”

Su Huai said calmly: "According to Director Ye's words, how can the World Academy of Sciences be willing to recognize the status of the inventor of Huaxia gunpowder." "There are arguments in the history books, there are arguments for customs, what more do you want?

Yelev said: "Su Shengren proved that Go is the origin of China, and what he took out was an ancient Chinese chess game, which swept the world chess world, then in your folk materials, there can be a unique use of gunpowder, which is better than the use of technology in other countries, then I have nothing to say, and I will discuss it at the General Assembly of the World Academy of Sciences immediately, and apply for your Huaxia to be the country where gunpowder was invented." ”

As soon as he said this, Mr. Wang secretly shook his head in his heart, and Yelev's question was straight to the point.

Although China invented gunpowder, it lagged far behind the West in application, otherwise it would not have been bullied by the countries of Europa in the era of hot weapons.

How did Su Huai come up with evidence?

But looked at Su Huaidao: "Director Ye's question is reasonable, the application of this gunpowder is different according to the national personality, and the direction of research and development is also different, I am just a literati in Huaxia, where do I know what applied science, but since Director Ye asked so, then I will apply for the application with the ancient formula of gunpowder in Huaxia." ”

Su Huai said, unfolding the folding fan with a demeanor and smiling: "The West made guns with gunpowder, while we Chinese people made a flower ...... with gunpowder."

Flower......?

How do you make gunpowder flowers?

Almost everyone at the scene was stunned when they heard it, how gunpowder would be Chinese medicine for a while, and then turn into a flower for a while.

"This kind of gunpowder flower is called fireworks. ”

Hearing the word "fireworks", many books in front of the TV set will exclaim in the hearts of Korean literature lovers, because there are many words for "fireworks" in the ancient poems of the Dynasty, which are generally interpreted by the literary world as an adjective -- "flowers are like smoke and ethereal clusters."

But no one has ever seen a real firework, what kind of flower it is.

Could it be that fireworks are not a description, but a "flower" made of gunpowder?

The audience was secretly shocked, so Su Huai asked the staff to come over and bring an arm-long cylindrical cardboard bucket.

Professor Hendry looked at the thing that looked like a detonator, and couldn't help but look at it and sneered: "Didn't Mr. Su want to show flowers? Why did you take out this kind of thing again, what kind of weapon of mass destruction is this?"

Su Huai smiled slightly: "How dare you, I'm afraid that your country will bomb us, this is just a kind of Chinese fireworks, if Professor Heng thinks there is something wrong with me, it is better to come up and try it." ”

Su Huaiyu was provocative, and Professor Hendry also wanted to expose his tricks, so he also walked up, took the colored bead tube, looked carefully, found the lead in front of him, and was immediately surprised:

"Isn't this just a firecracker?"

Ordinary firecrackers are the size of a fingernail, and the largest one is the size of a palm, but this colored bead tube is as long as an arm, and this ignition and explosion are afraid that it can blow up a hole in this stage.

Su Huai said with a smile: "Professor Heng don't be afraid, the gunpowder used in fireworks and firecrackers is different, the burning speed of firecracker powder is extremely fast, and the burning speed of fireworks is relatively slow...... So fireworks just burn, they don't explode. ”

Hendry was originally a little scared in his heart, but seeing Su Huai looking at him with a smile on his face, the audience also smiled, thinking that if he was scared on stage, he was afraid that this person would lose his fortune, so he forced himself to calm down and sneered:

"Oh, I see, it's just igniting the gunpowder in it, isn't this principle the signal flare used by the military?"

The audience was disappointed when they heard it, and they thought that Su Huai had come up with some secret weapon, it turned out to be just a signal flare, this kind of thing may be rare in ancient times, but everyone has seen it in modern society.

It has been widely used in war.

"It's similar to flares, but there's a difference. Su Huai explained:

"Fireworks are mainly set off by the ancient Chinese people in festivals, and a beautiful visual effect will have different colors. ”

Speaking of this, he asked Yelev: "Director Ye should know how to color the flame, right?"

Yelev knew that Su Huai was using his mouth to popularize science, but he also cooperated:

"When gunpowder is burned, copper will turn green, when strontium nitrate and strontium carbonate are added, the flame can turn red, and when sodium nitrate and sodium oxalate are added, the flame will be yellow..."

Hendry listened, but grinned even more happily: "The signal flares of various countries have long had flames of different colors, and the fireworks of the ancient Chinese people may not be regarded as a practical technology that other countries and nations do not have, right?"

Su Huai knew that he was not talking about the effect of fireworks with his mouth, so he said to the hostess Jenny:

"Now let the staff put this fireworks outside and let the audience see the effect. ”

Jenny reported the situation to the broadcast room, and at this moment Director Kai felt that Su Huai had completely controlled the situation, and in the hotline, there were already more and more people supporting him, thinking that if the staff demonstrated this signal flare, I was afraid that it would be difficult to thwart the limelight of Su Shengren, so he said:

"Let all the guests go to the rooftop of the building and go live together. ”

Jenny was stunned and said, "Now the show has run out...... And we didn't have any live streaming equipment. ”

"Isn't the rooftop on the roof of the building rehearsing a concert by McJackson? ”

After confirming everything, Jenny took the microphone and asked the judges of the various Academies of the World Academy of Sciences on the scene:

"Mr. Su proposed to go to the rooftop to verify the uniqueness of this firework, and there is nothing wrong with our equipment, does the Academy agree?"

This Harvard open class is a popular science program sponsored by the World Academy of Sciences, and if the new European station wants to make changes, it must ask these judges of the World Academy of Sciences.
