The whole structure is built at a certain angle, which should be an illusion, that is to say, in fact, the heights of the two angles on the horizontal plane are roughly equal, but there seems to be a gap in this closed space. It should be a trick of background and photography. Think about it. Not two flights of stairs, but two straight zebra crossings. You go straight from A to B, and then 180 degrees turn around and walk back. Is it back to the origin a? Then imagine that the whole thing happened in a closed square house, and then you tilted the whole house dozens of degrees. Of course, the design should cover up this trick. When you enter the room, there is no horizontal plane as a reference, and the handles, stairs and decorative paintings of the room are cleverly set with a false horizontal angle suitable for the inclination angle of the room. All this has become mysterious. As you can see through the lens, people are a little inclined when standing.

Now, the architects of Rochester Institute of Technology have broken the plane restriction and built a "Panlos staircase" on campus. I saw the characters in the film quickly climb the stairs and disappear in front of the camera, but at almost the same time, they came up the stairs at the lower corner of the camera.

Netizens enthusiastically discussed the possibility of this film, and some people said with certainty: "It must be twins! Some people infer from external factors that "if there are such stairs, warning signs should be set up, otherwise you will never get out in case of fire." " 」

Of course, the film has been cleverly edited, and the clue can be seen from the fact that the arm of the little boy in red grows out of thin air in 2 minutes 14 seconds. So the "Panlos ladder" doesn't exist? At least for now, and this movie is someone's whim, hoping to raise money on the Internet through shooting and then build a staircase to solve modern mysteries in the real world.
