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.
Ribbons (or visual indicators in general) wouldn’t have been stuck on there by a member of the public. It would have been placed there by technicians or maintenance guys to help with their tasks. Not common at home for obvious reasons, but not uncommon in commercial / public spaces.
Hollywood took an existing practice and made it ubiquitous because it was a convenient visual shortcut.
The practice is only used when the vents are hard to reach, Hollywood puts them eveyrwhere, like OP said behind a toilet, where the technician can easily verify by hand or with the actual tool to measure airflow so they have an actual metric to see if it’s deteriorating.
Its a Hollywood trope.
It’s not a thing in real life either…
HVAC techs will use the anemometer that’s part of their standard kit, they aren’t going to tie a fire hazard that collects dust to a duct….
If you see them left behind, that’s because the company was too cheap to cleanup their garbage, they would ONLY be used while the techs were actively diagnosing a persistent issue, but it should be removed when done.
Why do people perpetuate obvious fake Hollywood stuff? Do you think code will allow you to permanently affix something flammable to a duct that would be heated and can catch it on fire……?
Maybe american viewers will be so kind as to tell us in what kind of context they do see ribbons in real life and even post a few pictures?
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.
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.
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.
