Why is it in Hollywood movies every time there is a vent or AC unit someone has fixed little ribbons on it? Is that a thing americans do? Why? The vent in this movie is close to the floor in the toilets of a train. This implies someone got on all fours ON THE FLOOR OF A TRAIN’S BATHROOM to stick those ribbons there for a reason i can’t even begin to comprehend.
easy way to see if the vent is working or the AC is on
(and not just US, I have seen this worldwide)
Idk, usually I can just tell when I get hot or cold if the central air isn’t working myself.
It’s a thing for commercial buildings with stuff high up snd you can’t feel the draft from without a ladder, but not in houses or trains or anywhere else Hollywood slaps them. It’s not a thing, why are so many people trying to claim it is? Lol
Let’s see yours on your vents if it’s a thing then.
Why would you be using a camera? Is Hollywood inside you house lmfao. The vents are also easily reachable without a ladder, so you wouldn’t need a camera anyways? So why are you suggesting a camera?
This isn’t a thing in real life, never has, never will be. It’s a Hollywood trope…. Let’s see someone post a picture from their house, this isn’t a thing and people here are yanking your chain OP.
It’s to show the movement of air.
Not the ribbon, not the air. Mind is moving.

When I posted in this topic there were no other responses, so I gave you the answer. It’s literally the only reason any one ever does this and it’s done in movies to show the air moving if it directly affects the plot.
The only places I’ve seen that IRL, are stores or commercials. The ribbons help you see how much wind it pushes out, and make it look more desirable.
I’m guessing we only see it in movies as a hack to help us visualize a breeze.
And usually only in movies where airflow later stops for a plot-related reason. (e.g. the life support has shut off on a space station)
Actually in this movie it doesn’t matter. Something has been hidden behind that vent which the protagonist is about to findbout in a second.We will never come back to that bathroom.
I often see them in offices. People who are working 8 hours in an environment where thy don’t control the AC will often want proof that it is or is not working effectively. As there are potentially multiple vents along a duct these ribbons are a handy way to see how much the duct pressure varies across the room.
Because when people are hot, they think the air conditioning isn’t working, and the little ribbons are visual indicator that yes the air conditioning is actually running!
To answer the question about it being in a movie, it’s because the director needed you to know the air was moving through a visual means.
