Chapter 7 Section 7

"...First add a small amount of water to the pot and put it on the fire to boil." The figure of Yu Chuan was displayed on the screen, and the location was in the kitchen of the apartment.Although the structure of the house is exactly the same as Eshima Chinatsu's house, the interior decoration is completely different - it is the room on the second floor that he borrowed temporarily. "The water is boiling. Wait until the steam rises up like this in a large amount, and put the lid on the pot. Then let the pot cool down all at once." Yu Chuan put the pot into another large pot filled with cold water prepared in the sink, and then picked up a two-centimeter square ice cube.

"Use this piece of ice to block the steam hole on the pot lid. When the ice melts a little, it will fit better with the steam hole and won't slip off the pot lid. At this point, the pot lid will It is so firmly attached to the pot that it is difficult to separate from the pot.” Tang Chuan picked up the lid of the pot, as he said, the lid did not come off the body of the pot. "This is because the water vapor in the pot turns back to water after the pot cools down. Because the pressure inside the pot is low, the pot lid is pressed by the atmospheric pressure and cannot be separated from the pot body. We often encounter the lid of the soup bowl sucking in the water. The situation where the bowl cannot be removed is also the principle.”

Yu Chuan came to the living room and put the pot on the floor, beside which a long and thin sandbag and a vacuum cleaner had been prepared in advance. "This sandbag weighs about 40 kilograms, about the same weight as Ms. Eshima Chinaka. Because Ms. Eshima Chinaka was wearing a sweatshirt before she died, I also put a cover of the same fabric on the sandbag. Because sports The shirt has parts for the neck, the body, the arms, so I also cut two holes in the cover to put the vacuum cleaner wires through. First, I’m going to pull the wires all out.” He pulled the cord from the vacuum cleaner to the end and slipped the cord through the hole in the cover.

"The next steps are a bit tricky, but I'll do my best. I'm going to transfer this sandbag to the balcony—OK!" After moving the sandbags to the balcony, Yu Chuan moved the vacuum cleaner to the glass door.Then, he closed the glass door until there was only a gap of about five centimeters left. "In this way, even if the wire is dragged, the vacuum cleaner will be stuck in front of the glass door. This way, one end of the wire is fixed. What about the other end? Before that, let's lift the body to the ground. Go up to the balcony." Yu Chuan opened the glass door on the other side and came to the balcony again.He picked up the sandbag, put it on the railing like drying a quilt, then picked up the plug end of the wire, and slowly pushed the sandbag out.The sandbag was about to slip down, but fortunately, Tang Chuan held the wire tightly and prevented the sandbag from falling.

The camera lens was aimed at the vacuum cleaner, and the wires of the vacuum cleaner were stretched tightly, and the body of the vacuum cleaner was stuck in front of the glass door. Yu Chuan grabbed the wire tightly and walked into the house. "Next, the pot from just now is about to appear." He dragged the pot to his side with one hand, wrapped the wire around the handle of the pot lid, and stuffed the plug under the wire.Then he closed the glass door on the other side just like the other one, leaving only a few centimeters gap.The pot wrapped in wires was stuck in front of the glass door like a vacuum cleaner. After confirming that it was correct, Yu Chuan slowly let go.

"The device is now set up. Please wait and see what happens. The first thing that changes is the piece of ice that sticks to the steam hole of the pot lid. After a long time, the ice cube will melt naturally, and once the ice cube melts, the air will enter. Into the pot. After the air enters, the atmospheric pressure will no longer press the lid tightly, and the lid will come off the pot. In order to melt the ice cubes as soon as possible, I set the temperature of the air conditioner a little higher than usual. " The lens of the camera captured the entire mechanism setting, and Tang Chuan's figure had disappeared out of the lens at this time.

With a bang, the lid of the pot fell off.At the same time, the wire wrapped around the lid of the pot also bounced like a snake.Immediately afterwards, the sandbags disappeared from the balcony railing. Tang Chuan appeared in the camera again, and he walked up to the balcony and looked down: "Are you okay? Well, very good. Just leave it like that and don't move. I'll clean it up later. Thank you very much!" He said Turning his face to the camera side, he checked the vacuum cleaner, "The wires have almost all been coiled back, and the pot has also rolled over here. The experiment is over."

After Yu Chuan on the screen bowed his head and saluted, Xun turned off the power of the video recorder and monitor.After that, she carefully watched the expressions of her superiors. Mamiya leaned back on the chair with a straight face, while Kusanagi crossed his arms and stared at the ceiling.The rest of the senior detectives were almost all stunned. "That's the way it is," Xun said. "Kusanagi," Mamiya asked, "Did you go to beg Galileo teacher?" "I just wrote a letter of introduction." "Well——" Mamiya held his chin, "But then again, we don't have any evidence that Okazaki ever did this."

"Not really. But now that it has been proved that such a method exists, we have no reason to judge Okazaki is innocent." Xun said. "I don't need you to tell me about this." After Mamiya said it loudly, he looked around at his subordinates, "Now hold a meeting immediately to discuss how to correct the direction of the search in the future." Kusanagi glanced at Xun and gave her a thumbs up.
