Conan: I Am Not a Snake Spirit

After the code-solving activity, the five children gathered in the yard to play with fireworks sticks.

Chi Feichi, Dr. Agasa, and Subaru Okiya moved out a bunch of firework sticks and placed them on the ground. They gathered around and inserted the firework sticks into thin poles, and then connected the firework sticks with firecracker leads. .

"It turns out that the gift the doctor was talking about is this..." Mitsuhiko held a lit firework stick in his hand and looked at the one-meter-high large cardboard box next to him, a little dumbfounded. "But such a large box of firework sticks, wouldn't it? Is it too much?"

Haibara Ai stood next to Chi Feichi, watching Chi Feichi, Dr. A Li, and Okiya Subaru tinkering with the fireworks sticks, "You won't have too much after a while."

"Huh?"

"What are Brother Chi, Doctor and Mr. Subaru doing?"

The three children gathered around Chi Feichi curiously.

Conan walked to the side, looked at the movements of Chi Feichi and the others, and said with a smile, "Doctor, they want to set off many fireworks sticks at the same time, right?"

"Yes," Dr. Ali said with a smile, "Feichi heard that I wanted to buy fireworks sticks, so he asked me to buy more, preferably a big box. We can make a firework tree made of fireworks sticks!"

"Is this Brother Chi's suggestion?" Haiyuan Ai was a little surprised.

She thought it was the doctor's suggestion, but she didn't expect that her brother was actually interested in playing with fireworks sticks!

"That's right," Dr. Ali smiled and winked at Haibara Ai, "It's an offer that's hard to refuse, right?"

Haiyuan Ai nodded. Since her brother was interested in setting off fireworks, there was nothing wrong with buying some more fireworks for everyone to play with, but...

"Set off a large number of fireworks sticks at one time will produce a lot of sparks, which can easily cause fires," Haihara Ai reminded, "Although we set off outdoors and at a distance from the house, we still need to take fire prevention measures, right?"

"Don't worry, I've already planned this!" Dr. Ali looked into the room with a smile, "After the fireworks tree is ready, I will put the Pululu jelly I studied some time ago in the yard and spread it on the ground. Let it soak up the water so you can use it as a fireproof mat!”

"Pululu jelly?"

The three children looked confused.

"what is this?"

"It's a polymer absorbent powder I researched," Dr. Ali said with a smile. "General polymer absorbent powder can absorb more than ten times the weight of water in the powder, and the water inside will not be squeezed out under pressure. Come out, and the Pululu jelly I made can absorb hundreds of times its weight in water. As long as you pour water on the dry Pululu jelly, it will suddenly expand! The most important thing is that it After absorbing water, it will store the water inside, so even if a lit firework stick falls on it, it will go out soon!"

The three children's eyes lit up.

"Wow! That sounds so fun!"

"Doctor is so awesome!"

"I want to see that jelly now!"

"It's Pululu Jelly," Dr. Ali deliberately put on a serious look, "If everyone wants to see Pululu Jelly as soon as possible, then let's help!"

"good!"

The three children responded enthusiastically.

Nanatsuki Koshimizu stood by the yard and called Miwako Sato. When he heard the energetic voices of the children, he turned his head and looked over. He smiled and said to Miwako Sato on the other side of the phone, "Mr. Ike and Dr. Ike are taking care of the children." We do handicrafts..."

Three children joined the manufacturing team, and Haihara Ai and Conan naturally couldn't run away. They helped insert the firework sticks into the thin poles that served as branches.

The firework tree that Chi Feichi plans to make is not complicated. He only needs to insert the firework sticks on the poles prepared in advance to make firework stick branches, then screw a large number of firework sticks to the stand to serve as tree stumps, and then Combine branches and stumps to create a firework tree.

The really complicated part is to connect the firecracker fuses to the branches and stumps of the fireworks tree so that the fireworks sticks on the entire firework tree can be ignited by one fuse.

The children helped insert the fireworks sticks onto the poles. The fireworks tree was made much faster than before. Ike Feichi and Okiya Subaru concentrated on connecting the fuses, while Dr. Agasa was responsible for leading the children to complete the branches and stumps. .

Koshimizu Nanatsuki came back after making the phone call and found that everyone had already made branches and stumps. He was surprised, "Are you moving too fast? I wanted to come over and help right after the phone call!"

"It's just a matter of inserting fireworks sticks on the pole, it's very simple," Mitsuhiko said with a smile, "It only took me two minutes to make a branch!"

"The children each helped make two branches!" Dr. Ali said with a smile.

Koshimi Nanatsuki responded with an expression of admiration, "Everyone is so awesome!"

The three children were so happy that they wanted to assemble the firework tree with their own hands. However, since assembling the firework tree was more troublesome and the branches could easily hurt the children if they fell, Dr. A Li stopped the children.

"Then let me take some photos." Mitsuhiko took out his mobile phone and took photos of the raw materials, finished branches and tree stumps. He flipped through the photos to check with satisfaction, "Okay!"

"Misuhiko, what are you doing taking pictures of raw materials?" Ayumi asked curiously.

"We haven't determined the topic for our summer homework yet," Mitsuhiko said, "If we want to make a fireworks tree for our summer homework, we can use this as a reference!"

Chi Feichi: "..."

Are students already on summer break?

That's right, the next theatrical version seems to take place during the summer vacation.

"I think it's good to make a fireworks tree for summer vacation homework," Ayumi said with a smile, "Summer and fireworks are the best combination!"

"But the summer homework is to be brought to school for Teacher Xiaolin to see. It will be very troublesome to move the fireworks tree to school," Conan reminded. "If the leads are torn or messed up, there will be no way to put the fireworks back at once." Fireworks sticks were lit in the trees.”

Haihara Ai added aloud, "Besides, there are many children in the school. It is not very safe to move the fireworks tree to the school to set off. Teacher Xiaolin may not agree with us setting off the fireworks tree."

"If we can't set it off, everyone won't be able to see our complete work," Mitsuhiko hesitated, "Although this can be considered as completing our work, people won't think our work is very impressive!"

While the children were discussing their summer vacation homework, Chi Feichi and Okiya Subaru assembled the fireworks tree and placed it on a flat grassy area in the yard.

Dr. A Li went back to the room and took out a bottle. Seeing that the children were still discussing, he coughed deliberately, "Ahem! Don't you all want to see my Pululu Jelly? I'm going to start showing my Pululu Jelly. oh!"

"Let's discuss the summer vacation homework tomorrow!"

The three children hurriedly ended the discussion and looked at Dr. Ali expectantly.

Even Koshimizu Nanatsuki, Ike Feichi and Okiya Subaru wanted to see what Dr. Agasa's new invention was like, and focused their attention on Dr. Agasa.

Dr. A Li was very satisfied with everyone's reaction. He unscrewed the bottle and sprinkled a little of the powder in the bottle on the grass near the fireworks tree. "First, sprinkle the Pululu jelly powder on the grass..."

Yuantai stood nearby, looking over his shoulder to watch Dr. Ali sprinkle the powder, and asked doubtfully, "Doctor, is it enough to just sprinkle this small amount? Don't be stingy!"

"This is a super-effective polymer absorbent powder," Dr. Ali affirmed seriously, "Just sprinkle a little on it and it's enough!"

Nanatsuki Koshizui watched curiously, "Speaking of polymer absorbent powder... it's the one used in diapers, right?"

"That's right," Haiyuan lamented, "but the polymer absorbent powder studied by the doctor has a stronger ability to absorb water."

Conan: "..."

The things that the PhD researchers came up with are really all kinds of weird.

Dr. Ali carefully put the bottle back into his pocket, pulled the water pipe used to water the flowers by the yard, pulled the pipe to the place where the powder was sprinkled, and asked Chi Feichi to help open the faucet.

After the water flowed out of the pipe, the powder sprinkled on the grass by Dr. Ali came into contact with the water and swelled into a white cotton shape. As the water continued to pour in, the nearby powder also began to swell, and soon it was in the fireworks tree. A thick carpet twenty centimeters thick, as white and soft as clouds, formed around it.

"Okay, Fei Chi, you can turn off the faucet!" Dr. Ali asked Chi Fei Chi to turn off the faucet. He turned around and saw the dull expressions of the children, and smiled smugly, "How is it? It's great!"
