"What exactly are you trying to express?" My brother was also a little confused by me.

"You say, could it actually be ...... A table, or a chair, is the last hidden organ of this house? I hesitated to say this. Actually, I'm very unsure.

"What do you mean?" My brother was finally attracted to me and looked at me seriously.

"In other words, the last mechanism is not a button or anything that is fixed in place, but a specific item." I racked my brains to try to explain the idea that popped into my head to my brother, but I found it really hard to describe in words, "For example, we just need to find something in this house that makes a table or a chair, and put them together, and we can find a way to touch the last mechanism." Because that uncle has always lived here, it is impossible not to use the table and chair at all. "That's so unrealistic, no one can live without a table and a chair, right?

"Make up a table and chairs?" My brother seemed to be struck by my sudden strange thought, "Can that kind of thing still be combined?" ”

"Of course." I nodded, and tentatively began tapping lightly on the walls.

According to my reasoning, there must be a lot of hidden folding furniture in this house, otherwise it can't be so empty, there is basically nothing, so how to live?

Many of her designer classmates have been teaching me about the development of modern folding furniture in and out during the two years or so of her college years - more and more people can't afford to afford large houses, so more efficient space utilization has become a focus of more and more attention. Once the furniture has been designed to fold, it is extremely likely that there is nothing in one's home, but in fact it is easy to pull out the furniture that needs to be used everywhere when it is time to use it.

And those designers are learning this aspect of design. Although they can't design the furniture composition through repeated calculations to perfection like the interior engineers of the engineering school, they always provide a steady stream of creative ideas and sketches. And in the process of educating me about science, they also taught me how to find a way to put most of the hidden folding furniture in the house through a few simple tricks.

First of all, nature is percussion. In many places where there is hidden furniture, the sound of knocking is very different from hitting the wall directly. Some will make a very empty sound, others will sound dull, and some may have a direct and noticeable echo.

I tapped carefully around the walls of the room, lest I miss any point in the wall that could be suspected.

Sure enough, I was about to knock on the kitchen when there was a very empty "knock" on the wall.

I paused, pressed my ear to the wall, and tapped it again as if in confirmation: "Knock."

It is indeed here, and the general wall should be very solid "click" sound.

Next, make a few more extended taps around the area to ensure that the hidden furniture occupies the area of the wall, floor or even ceiling.

I circled around the place and tapped a few more times on each of them. When the boundary was basically determined, I made a shallow mark with my fingernail at that point.

In the end, I determined the positions in all four directions. I began to grope around the boundaries I had set out again.

According to the students, don't break it violently at the border, as it will do nothing but break the open mechanism. It's about groping gently. In general, the way to open is to scratch it apart in addition to pulling.

Sure enough, there was nothing on the border, ruling out the possibility of a split. Then it should be a pull. I reached for the center of the demarcated border, carefully covered it, and gave it a gentle push.

It really pushed, and the whole wall sank in a little with my push. I heard a soft "click", and when I gently let go of my hand, the entire wall that had been pushed in was peeling off along with my hand.

I hurriedly stepped back, and the "peeling" wall slowly descended and descended on its own along a fixed track, eventually taking on a vertical right angle to the original wall, and just stayed there.

I turned back to my brother, who was already a little dumbfounded, and said, "Look, it's like this. A table made of walls. ”

"It's not called a 'combination', is it? It's magic. The younger brother swallowed, still looking at all this in a daze, "How did you find out?" How did I come up with it? Have we touched the mechanism now? What about antibacterial clothing? ”

"Why do you have so many questions, one by one." I pursed my lips and patiently explained to my brother one by one, "Didn't you notice the table where you put those test tubes and labels on the second floor?" That platform is connected to the wall, right? I thought it would be fun, and I set aside a section of the wall to be used as a table. But when I found out that the house itself didn't have a table or chairs, I thought it was strange - why not just use the table? It's still easier to carry, huh? This design is really strange, and it also affects the redesign of the entire interior. In case the homeowner wants to change the decoration, furniture and so on, in fact, it is largely limited by this seemingly novel platform. ”

"So why build this platform? I can think of these shortcomings, and it is impossible for that uncle and the designer hired by that uncle not to think of it. Could it be used for something else? Thinking of this, I thought of the folding furniture design that your sister An An's classmate told me. I thought, is that table actually foldable and retractable? Actually, it's the kind that can be retracted from the wall at any time? ”

"Then I used the identification method taught to me by your sister An An's classmates, but I didn't expect to really find it. And there really is. As for the mechanism, I don't know...... However, if you look for the mechanism in the same way as folding furniture, you may be able to find it. After a big sigh of explanation, I pointed to the wall behind me and said, "Got it so let's get started." I'll show you how to tell. Hey, I know your character, if I don't explain it to you right away, you won't be able to do anything. ”
