"You two?" The waiter's gaze swept over the two people's faces, which were completely covered. "What are your identities?"
Chien Chih-chen said, "They are students from the school next door."
Upon hearing this, the waiter couldn't help but feel a sense of respect for the two of them.
That school is full of geniuses, and they are said to often break through problems with some incredible things. Several episodes of the "Approaching Science" program were filmed there.
The waiter nodded and said, "Alright, you two go and see what's going on, but I won't be responsible if you get hurt by accident."
Jian Zhizhen smiled and nodded, then pulled Qin Yubai along.
Qin Yubai looked down at their clasped hands and thought of how he had tried to hold her hand several times before, but had failed because she was too shy.
But now it just happened so naturally that we ended up holding hands.
We need more of these kinds of emergencies!
The two followed the waiter into the back alley.
Many onlookers also came to watch the spectacle, eager to see how these two students from Beicheng would solve the case.
The owner of the hot pot restaurant and the owner of the ice cream parlor were choking each other.
They were being pinched so hard their eyes were rolling back, but they just wouldn't let go.
There were also several chefs and waiters standing nearby, all shouting "Go! Go!"
Keep going! If you keep going like that, someone's going to die!
Jian Zhizhen sighed inwardly and silently observed the crime scene.
The trucks used for ice cream parlors and hot pot restaurants are both used for deliveries; the entire back of the truck is essentially a large refrigerated container.
These freezers are designed to be extremely airtight to prevent food from being contaminated by external sources.
The ice cream parlor's cart was indeed as the waiter described; although it wasn't quite like a sheet of iron, it was definitely squeezed very, very flat.
The car belonging to the hot pot restaurant was in perfect condition, with only minor scratches on the front, but these looked like old, minor damage, not like it had been in a major collision.
Jian Zhizhen inspected the area and asked the ice cream parlor owner, "Boss, you're quite particular about hygiene. The corners of the carriage look very clean. Did you use a steam cleaner?"
Steam cleaners use 100-degree high-temperature steam to clean and sterilize. Many sealed compartments used for transporting food are cleaned with steam cleaners.
When the owner of the ice room heard someone praising him, he proudly agreed, even though he was being choked: "Yes, our ice room is all about cleanliness and hygiene! Every day when I bring the ingredients back, I clean them with a steam cleaner."
Chien Chih-chen guessed the same thing.
Because these kinds of carriages usually have ice crystals, water stains, and the like.
But the flat carriage in front of us is really clean; it's clear that only a steam cleaner could achieve this effect.
All the evidence at the scene proved that she and Qin Yubai were right.
She then said directly, "That's right. Boss, your car wasn't hit by someone, it was flattened by atmospheric pressure. When you were disinfecting yesterday, the temperature inside the car was extremely high, but it rained shortly after you finished cleaning. The rapid cooling caused the air inside the car to liquefy, so the air pressure inside was low. Then the air pressure outside was high, which flattened your car into a flatbed."
The ice cream parlor owner could understand her.
Because this principle is very common in life:
Fill a heat-resistant plastic bottle with hot water and tighten the cap. As the water cools down, the bottle will flatten; this is due to air pressure, not thermal expansion and contraction.
Although he understood the principle, the ice cream parlor owner still didn't believe it: "Impossible! Absolutely impossible! My carriage is made of solid steel plates! Do you think it's a plastic bottle? That air can flatten it?"
Jian Zhizhen smiled good-naturedly: "Then let us do an experiment for you."
After saying that, he turned to Qin Yubai and said, "Bai Bai, go!"
Qin Yubai: "..."
The tone sounds like they're unleashing the dogs from behind closed doors.
However, he still followed her instructions and went to ask the boss, "Boss, do you have large oil drums?"
Many restaurants and dessert shops have large iron drums for storing rapeseed oil, cream, etc. These drums are large, sturdy, and have excellent sealing properties.
The two bosses were still unwilling to let go of each other's hands, continuing to choke each other's fate.
But the hot pot restaurant owner was eager to prove his innocence, so he turned around and instructed his chef: "Quickly go and get a big iron bucket."
Chien Chih-chen added to the ice cream parlor owner, "I also need the steam cleaner you used yesterday."
The ice cream parlor owner also turned around and instructed his chef to fetch it.
Soon, all the items were ready.
Jian Zhizhen took out a professional measuring ruler from his backpack and measured the thickness of the car wall. The thickness of the oil drum wall was the same.
Then, using a portable hardness tester to measure the hardness of both items yielded the same result.
Next, Qin Yubai inserted the steam cleaner into the inner wall of the large oil drum, cleaning it while also heating the inner wall and the air inside.
Then, put the lid on and seal it.
Then pour cold water on it to simulate the previous rain.
Not long after the oil was poured, the oil drum made a loud "bang"!
The oil drum suddenly shrank inward!
This huge oil drum was also compressed into a large iron plate by the air pressure!
Both bosses were shocked, staring at the large iron barrel with disbelief.
Don't underestimate atmospheric pressure. Let alone oil drums and freezers, even professional explosion-proof oil tankers can be crushed into iron plates by atmospheric pressure in a short time.
Jian Zhizhen said to the ice cream parlor owner, "The experiment has now proven it, but if you still don't believe it, you have no evidence to prove that the hot pot restaurant owner hit it. Look at the slight scratches on the front of his car. If he had hit it, would his car have only been damaged this little?"
