He dug a shallow pit in the sand and placed some of the charcoal from the bonfire at the bottom of the pit. Then, he covered the burning charcoal with some small pieces of charcoal left over from yesterday's burning.
He placed the coconut shells into the pile of charcoal and covered the surroundings with sand, leaving a small gap as an air intake. The advantage of this was that the fire would continue to run upwards and the fire could be concentrated at a single point.
Moreover, the burning time of the charcoal would be greatly increased, and the amount of charcoal used could be saved.
After a short while, the charcoal pieces were ignited by the charcoal fire and burned fiercely. Because the surroundings were covered with sand, the fire was very concentrated.
After a while, the bottom of the coconut shell began to turn black and showed signs of carbonation. However, after the surface of the coconut shell was carbonised, it did not burn. Only the carbonised parts spread a little.
"Streamer, are you going to boil water? The shell of this coconut is made of wood, right? Aren't you afraid that it will leak?"
"F * ck! Is the host going to do something again? Using coconuts as a kettle?"
"I think the streamer is a little thirsty. He actually used coconut shells as a kettle. Did he forget that coconut shells can be burned?”
"That's enough, the streamer isn't blind. Can't he see that the coconut shell has already been carbonized? But do you see the streamer getting anxious?"
"Sigh, you guys don't say. Logically speaking, the bottom of the coconut shell has already been carbonized to such a state, so it should have burned long ago. However, the coconut shell actually doesn't burn. What's the principle behind this?”
With this reminder, everyone's attention was focused on the coconut shell. In their minds, the coconut shell had already been carbonized to such a state. It should have been burning a long time ago.
However, reality was just so magical. No matter how hard the coconut shell was carbonized, it could not burn. It was as if magic had been cast.
"Do you think this streamer knows magic? Why do I feel like the streamer is always so magical?”
"Yeah, I also think that this is like magic. Although I know that magic is fake and that it must be based on some scientific principle, I just can't think of what principle Zhou Ye used.”
While everyone in the live broadcast room was discussing, the water in the coconut shell on the charcoal fire had already begun to steam. In a short while, the water was boiling.
He removed the coconut shell from the charcoal fire. After the bottom of the coconut shell came into contact with the air, a small spark instantly appeared, but the water in the coconut shell did not leak.
He extinguished the flame at the bottom of the coconut shell on the sand and left it there to cool down.
"F * ck! Was this magic? The coconut shell was burning, but it still didn't leak?”
Everyone could not believe it. They could not understand at all. The coconut shell was burning, but it did not leak.
In the live broadcast hall, the host, Qian Hao, looked at the live broadcast in disbelief and asked Professor Chen,
"Professor Chen, what is the principle behind this? The coconut shell was already burning, but why wasn't it leaking?”
"This coconut shell is made of wood. Logically speaking, it doesn't leak. It should be because the coconut shell hasn't burned enough. The interior is still intact, so it doesn't leak.”
Professor Chen paused and continued,
"But this is also what I'm puzzled about. Logically speaking, the temperature of the charcoal fire is very high. Zhou Ye placed the coconut shell on the charcoal fire for such a long time.”
Professor Chen still couldn't figure it out and shook his head helplessly. He was still wondering why the coconut shell didn't leak.
At this moment, Xu Wei suddenly said,
"I think it might be because the coconut shell is filled with water. You know, the boiling point of water is only 100 degrees Celsius.
When the water reached its boiling point, it would only turn into steam. The excess heat would be dissipated through the evaporating of the water.
Therefore, the interior of the coconut shell was always maintained at 100 degrees Celsius, far from the burning point of wood. This was the reason why the coconut shell would never leak.”
"Yeah, the principle of heat transfer. Why didn't I think of that?”
Qian Hao said regretfully. He had learned about the principle of heat transfer when he was in primary school. Why didn't he think of evaporating water to dissipate heat?
Xu Wei looked at the shocked host and smiled mischievously. She said teasingly,
"Uncle Qian Hao, do you think this is the end? If I were to mention the application of heat transfer again, you might faint from shock later.”
Faced with Xu Wei's mischievousness, Qian Hao's forehead was full of black lines. He looked at her with a hint of resentment.
"I'm not even forty years old yet. I'm still a baby. Can you not call me uncle? Am I that old?"
"Haha, strictly speaking, with Qian Hao's current age, he is indeed a young man, but your appearance is indeed a little anxious.”
The host Qian Hao's resentful gaze made Professor Chen laugh out loud and tease him a little.
With the current average lifespan of 150 years, Qian Hao, who was less than 40 years old, was indeed a young man.
Although the current law stipulated the standard of adulthood, it was still a continuation of the 18-year-old rule on the mother planet.
However, due to the advancement of science and technology, the lifespan of ordinary people reached about 150 years. After genetic modification, they could even reach more than 300 years old.
So strictly speaking, Qian Hao was indeed in the category of young people, but his appearance was indeed a little anxious. This was also the reason why Qian Hao was often teased by others.
"Sigh, alright, I do look a little old. Unfortunately, the genetic modification drug is too expensive now. With my current salary, I don't know how long I'll have to save.”
Qian Hao teased himself. At the same time, he was cursing those profiteers in his heart. A dose of genetic modification gene serum was really too expensive.
"However, Xu Wei, what exactly is the heat transfer application you mentioned just now? I want to hear what can shock me. I've also experienced great storms.”
Qian Hao pulled the topic back. As a qualified host, he had the ability to control the scene.
"Do you really want to hear it? Then you better be prepared. If I tell you, I guarantee you'll be shocked.”
Although Xu Wei was a little mischievous, she also knew that they were recording a program now. The necessary interaction was still needed.
"Actually, after I saw Zhou Ye's method, I understood the principle behind it. Then, I thought about it and thought of a very interesting possibility.”
"Hurry up and say it. Stop wasting time. If you don't want to tell me, I'll ask Professor Chen.”
Qian Hao was a little anxious by Xu Wei's procrastination. For the sake of the program's effect, he turned to Professor Chen and said,
"Professor Chen, you look so confident. You probably thought of it too. Why don't you tell everyone?”
