Chapter 137 Rupert's Tears

"So hard? What is that? Why does it look like glass?"

Wang Husheng muttered softly.

Ye Yuan glanced at the booth, and said with a mysterious smile:
"That's glass"

"Huh?" The two couldn't believe their ears, wouldn't the bullet break the glass?Bulletproof glass?

Ye Yuan knew what these two guys were thinking, and then added, "Ordinary glass, the very ordinary kind."

At this moment, the two of them were completely confused. The boss said that even bullets would not break, and at the same time said that this is ordinary glass. Is this contradictory?
The three of them were chatting here, and the girl who set up the stall probably looked at the people around her, and there were fewer people who watched more and played, so she looked in Ye Yuan's direction.

I have to say that Wang Husheng's appearance is still very strong, the girl smiled slyly, and said to Wang Husheng:
"Little brother, you are so strong, you must have great strength, don't you come and try?"

Wang Husheng was suddenly named by such a young girl, and he didn't expect it.

According to his personality, since his sister papers have already been called, why do he have to go up and try, but Ye Yuan just said that this glass is not broken by bullets, so is it possible for him to go up and break it?

Wang Husheng saw that everyone around him looked over. At this moment, he glanced at the glass tadpoles on the table, and then at Ye Yuan. He was about to go up and have a try. Anyway, 50 yuan is not too much.

Ye Yuan didn't want to be troublesome at first, but he didn't expect the girl to find Wang Husheng. He grabbed Wang Husheng who was about to go forward, turned to the girl and said with a smile:
"Miss, let's talk about the rules first."

When the girl saw that someone was hooked, she quickly said the rules.

"50 yuan once, if you break this glass, you win, and I will get 10 times the bonus. How about giving it a try, little brother?"

Ye Yuan glanced at the girl strangely, this girl seemed to be in her early 20s, she should still be a college student.

She was wearing a dress, not a famous brand, and a pair of casual cloth shoes on her feet, which looked very clean, but the clothes only cost 200-300 yuan.

Ye Yuan originally didn't want to expose the girl, but who made him name Wang Husheng?It's no wonder I can't blame myself, Ye Yuan walked to the table with a smile, and scanned the QR code to pay.

Seeing that Ye Yuan had already paid, the girl picked up a glass tadpole, held the tail of the glass tadpole in her small hand, and put the big head of the tadpole on the table.

Ye Yuan was happy seeing this.

"Miss, you are like this, I can easily hurt you if I break the glass, should I hold it by myself?"

There was a hint of panic in the girl's eyes, but it disappeared quickly.

"No, you can't hold it well. I'm afraid of hurting others. After all, this booth is mine, so I should hold it."

Ye Yuan thought for a while and said:
"Okay, then you take the other end. I need to hit the tail. After all, the tail of Rupert's tears is easy to break. If you are afraid that I will hurt someone, how about I crush it with my bare hands?"

After finishing speaking, Ye Yuan looked at the girl with a smile.

When the people around heard that Ye Yuan could crush this piece of glass with bare hands, they all laughed, especially the young man who had beaten it once just now.

"Just blow it."

Ye Yuan didn't care what the people around him said, just stared at the girl.

At this time, the girl's face was already flushed, and she didn't know how to proceed, and the people watching the fun also discovered the problem.

The Rupert's tears that Ye Yuan mentioned just now have been heard by careful people. What is it, could it be the glass tadpole on the table?How does it sound like the name of a gemstone?

The girl glared at Ye Yuan, took out 50 yuan in cash from her backpack, and threw it directly on the table.

"I don't do your business, hum!"

Ye Yuan put away the money and shook his head.

Everyone knows by this time that there must be a mechanism for this thing, and many younger people have already used their mobile phones to search for Rupert's Tears.

The girl saw that it was impossible to do business if this continued, so she put away the payment code and the hammer, and left straight away.

At this time, someone had already found the answer, and said loudly, "Damn it, I was deceived, this thing can't be broken without a bullet on the tail."

Ye Yuan also left here with Wang Husheng and You Zhiyong.

"Boss, what exactly are those Rupert's tears you're talking about?"

Wang Husheng asked curiously.

As Ye Yuan walked, he explained the origin of Rupert's tears to the two behind him.

"Rupert's tears, also known as Dutch tears, are tadpole-shaped glass tears formed when molten glass is dropped into ice water by gravity.

This kind of glass teardrop has wonderful physical properties. The teardrop itself is no different from solid glass, and it is safe and sound when pinched and hammered.

However, if you grab its slender tail and apply a little pressure, the whole glass tear will burst and shatter in an instant. "

"Why is that?" Wang Husheng continued to ask.
"The principle of the shattering of Rupert's tears is called "crack propagation", which stems from the unbalanced pressure inside it.

When molten glass is dropped into ice water, the surface of the glass cools rapidly to form a crust, and the shell
The glass underneath is still liquid.

When the glass in the core is also cooled and condensed, due to the volume change, the liquid glass will naturally shrink toward the already solid shell.

As a result, the glass close to the surface is subjected to a large compressive stress, while the core position is pulled to the surroundings and subjected to tensile stress.

When the tail is damaged, these residual stresses are released rapidly, making the crack spread throughout the whole body instantly and fragmented. "

Ye Yuan patiently told what he knew.

The two of them still haven't fully digested these, and feel the magic of this thing.

It was already noon when a few people were strolling around. During this time, they had already seen a lot of high-end ornamental fish and some weird fish. Ye Yuan also took out his mobile phone to take pictures from time to time to check some ornamental fish species that he didn't know much about. .

It was noon soon, and the three of them did not return to Deng Kai's booth.

Instead, they walked out of the exhibition and settled for lunch for a few people at a small restaurant nearby.

There were a lot of people in the restaurant, maybe because of the nearby exhibition, the restaurant was already full, the three of Ye Yuan managed to find a table in a corner.

The waiter took the menu, and after a few people ordered a few home-cooked dishes, the waiter went to receive the new guests.

At this time, Ye Yuan found that there were 2 girls sitting on the table not far from him, and one of them was the one who just made money with Rupert's tears in the exhibition.

Strictly speaking, this girl is not a liar, after all, it is indeed glass, but to break it requires a method, and this method is unknown to ordinary people.

Ye Yuan can tell that the family conditions of these two girls are very average, it can be seen from the clothes they wear.

The girl at the exhibition was poking the noodles in her bowl with chopsticks, muttering to herself, "Today is really unlucky. I was exposed before I made any money. It's all your fault. If you say this method is feasible, who knows that so many people know it?" Rupert's Tears"
