There is something in my house, but I don't know its name. It is as big as a bowl, with many holes around and at the bottom. It feels like metal hardness, and it is very light in the hand. It looks like a copper basket. I heard from my mother that my grandfather found it on the mountain. After my grandfather died, my mother told me that it was a treasure. What treasure is it? My mother didn't tell me.

Last year1February, when I moved to a new house, a strange thing happened. I put this dirty copper basket in the pool and found that it could float on the water. How can metal float on the water? I thought I was blind, so I pushed it into the water and tried again. Every time it comes up. In order to prove whether it is metal, I took out an electric meter from the drawer and touched it with a measuring needle. The pointer of the electric meter swung. After repeated tests, it is still the same result. I thought about it and decided to give it a try in the "Exploration and Discovery" section of the TV station.

After I picked up the phone and dialed, I told the other party what happened.

The next afternoon, the film crew arrived as scheduled. After everyone introduced each other, the reporter asked, "Where is this thing? Let's see. " "here." I held it in my hand, and the reporter looked forward and asked, "Can you make a demonstration?" In front of the camera, I put this thing in the pool and pressed it to the bottom. It floated slowly. I didn't expect the reporter to see it clearly. I did it again and again.

"It's really strange." The reporter held it in his hand and read it over and over again. "Very light." She doesn't understand either.

Me: "Yes."

Reporter: "Well, let's invite an expert. Xiao Liu, please call this number. "

Xiao Liu is a reporter's assistant. I'll contact you later. Xiao Liu said let me take this thing to an expert.

I walked with the reporter, came to the institute, and found the expert on the phone. His surname is Huang.

At the scene, Professor Huang tried several times and was puzzled.

The reporter asked: "Professor Huang, why does this thing float?"

Professor Huang said: "Maybe this thing was not made of copper from the beginning, but it was sprayed with a layer of metallic paint."

I looked at it and found traces of wear at the bottom, so I said, "The material here is the same as that without grinding. It shouldn't be painted. Let me show you. "

The reporter suggested that the professor continue to do the experiment.

Professor Huang used a metal detector to detect and confirm that it was metal, and then said, "Only metal substances lighter than water, such as potassium, calcium and sodium, can float on the water surface, but they will react chemically with water."

The reporter asked again: "Professor Huang, what metal is lighter than water and will not react with water?"

Professor Huang was puzzled and said that further tests were needed.

Professor Huang used various instruments, and after testing, he came to the conclusion: "This is a substance that has not been found in nature."

Reporter: "Who made this thing? What's the use? "

No one answered.

They asked me to take this thing to Beijing. In a research institute, many experts gathered, and they all wanted to solve the secret. Finally, they confirmed that this is a product that humans cannot make today. Later, several people took me to a place and asked me many questions. Let me keep this secret for the time being.

Today, when I was tidying up my clothes, I accidentally found a brochure in my mother's clothes. Wrote many pages. This booklet was written by my grandfather and recorded in detail what my grandfather saw. This shocked me very much. I decided to check it out.

20 12 March 19

The circuit burned several times at home, and the electrician scolded me: "I have nothing to do after eating."

I'm going to the library to look up some information tomorrow.

20 12 April 1

I met Professor Huang at the gate of the library today. He recognized me and said hello to me.

"It's you."

"hello! Professor Huang ".

"Have you worked out your treasure?"

"You can't figure it out, and I can't figure it out."

"You must have found something?"

"Why? I'm here to check some information. "

"oh? What book are you reading? "

"Quantum physics."

"Why are you interested in this?"

"Everyone has his own interests and hobbies."

"If you find anything, remember to come to me. This is my mobile phone. "

Something terrible happened today. My copper basket is missing. I asked Mingming, and he said he lost it when he took it to play with some children. I asked Mingming where he lost it, and he said he lost it while playing with Binbin downstairs. I looked for it, but I couldn't find it anywhere. Later, I asked Binbin and those children, and they all said they didn't know where they got it.

This is a bolt from the blue. I thought it was serious, so I called the police

The police are here.

"Did you call the police?"

"I reported it."

"You lost something at home."

"A bronze vessel like a bottle is a relic of my grandfather."

"You just go and find it yourself. Is it so important? "

"Yes, it is very important. It is best that you can block this community immediately. "

"Blockade area? You're not the only one. I will help you find it. "

The police took me to the property to check the video, and the community security guard said that the camera was broken. I seem to have hit the bottom. "Then go door to door."

"Are you kidding?"

"I'm not kidding. I'd better meet the leader of your. "

"Why do you want to see our leader?"

"I won't bother you. Can you introduce me to your leader? "

"Our leader is not available, you'd better find it yourself." Say that finish, the police left. I asked the security guard, "Who has been out?"

"So many people go out, and you don't know who it is?"

"Who do you think will take this thing?"

"Copper, of course, is a junk. Students, old ladies and thieves may also be involved. "

"Have scavengers ever been out?"

The security guard thought for a moment: "There seems to be."

"Where did he come from?"

"I'm not sure."

I can't seem to find it myself. I think I'd better get help tomorrow.

"Hello, is this the public security department?"

"yes."

"I'd like to speak to Director Tan of your company."

"What can you tell me?"

"I have something very important to talk to your director personally."

"Can't you talk to me?"

"This matter is confidential."

"Confidential? Can you tell me who you are? "

"No, please contact me immediately."

"Well, please leave your phone number."

I waited all morning, but I didn't see a reply. No, I can't wait any longer. I want to go to the district Committee. When I arrived at the district Committee, I was stopped by the guard before I entered the cordon: "Stop, you are not allowed to enter here."

"I want to see the secretary."

"The secretary has gone to a meeting."

"The deputy secretary will do."

"Register with the doorman."

Arriving at the reception office, the waiter asked, "What can I do for you?"

"Very important thing."

"Please line up in the reception room first and register your ID card."

"Can you see the deputy secretary? I have very important secrets and I have to interview them. "

"That depends on what you do." The waiter is very impatient with this.

Still can't see the big shot, so I have to find Professor Huang.

I dialed the telephone of Professor Huang.

"Hello, who's calling?"

"Is it professor huang? I am Teacher Song. "

What can I do for you?

"I lost that thing yesterday. Can you report it to Beijing? "

"The loss is your own business, not mine."

"Because the last time they returned it to me after studying it, let me keep it a secret for a period of time, maybe when to get it again. Not anymore. I want to tell them through you that this item is lost and will be reported to the public security organ for search. You and they are both in the same department. "

"Well, this item has no research value now. Lost it, lost it. "

"What if there is research value?"

"It depends on whether its value can alarm the top."

"What would they do if they could be disturbed?"

"Of course, I will try my best to find it."

"That's why I came to you."

"Did you really find anything?"

"Come to my house and I'll tell you, but you must keep a secret."

"all right." ?

I think this is the only way to find the copper basket.

In the afternoon, Professor Huang came to my home.

Ding Dong.

I opened the door and said, "Professor Huang, please sit down." I poured a cup of tea for Professor Huang.

Professor Huang: "Thank you."

Me: "I can tell you a secret."

Professor Huang: "Go ahead."

Me: "Let me ask you a question first. If there is a hole in this teacup, water will flow out, right? "

Professor Huang: "Yes."

Me: "This is because of gravity, Professor Huang. I want to ask you, under what circumstances will water not flow out? "

Professor Huang: "In weightlessness."

Me: "Yes, can you do weightlessness in your laboratory?"

Professor Huang: "The gravity of the earth can't be overcome, except in the sky."

Me: "This thing can be done."

Professor Huang: "No, I didn't put it in the water, and neither did I."

Me: "Lightning!"

Professor Huang: "Current?"

Me: "Yes, strong current."

Professor Huang: "You didn't just make me get your things back."

Me: "I won't lie to you. Didn't you see me in the library that day?" That's why I went. "

Professor Huang: "So you succeeded?"

Me: "Yes."

Professor Huang: "Where did you get such a strong current?"

Me: "This is my grandfather's personal experience."

Professor Huang: "Oh? Did your grandfather tell you? "

Me: "Yes, I have mastered all the mysteries of this thing, because it is so important that I didn't tell anyone."

Professor Huang: "Why did you ask me to do the experiment before? Don't you know the same? "

Me: "But then I found a diary of my grandfather."

Professor Huang: "What about the diary? Let me see. "

Me: "I can only tell you so much. There is a great mystery hidden behind this treasure. Only when we find it can we solve it. Please believe me. "

Professor Huang: "What do you want to do?"

Me: "Go back and talk to the leaders above and see how they react."

Professor Huang: "All right."
