How Do One-Way Mirrors Work?

[@justinlewtp]

I will never trust the mirror in the fitting room ever again

[@BrainStuffShow]

+Justin Lew (MC Gamer) No need to worry -- just cup your hands around your eyes and peer into the mirror! It'll be easy to tell if it's actually a one-way mirror.

[@hannobrandwijk9809]

Scottie Yes there is, put your finger against the glass, if there is a gap between your "2" fingers, then it's a real mirror. If there isn't a gap, you should go away fast;)

[@IntrovertReality]

Hanno Brandwijk This has been disproved multiple times

[@niveyoga3242]

[@alec4672]

I think I saw a comedy cop show where the suspects were in a lineup and this rookie cop turned on the light in the observing room and all the suspects saw the witness 😂 nice to see accurately applied science, specially in a comedy.

It was in kickin it lmao it was Funny

yes it is police academy

[@fahadkhanye]

God this was killing me how they made these mirrors work. Great info thanks!

[@BrainStuffShow]

^___^ Thanks for watching!

[@coolguysam11200]

Same here

[@Amityz72323]

I've been trying to figure this out for two freaking years but could never remember to look it up xD

[@beertjeswiss1023]

THX , everything i needed to know for my homework :P

[@BabuForTheFriends]

If you wanna test if a mirror is trasparent you have to put your finger against the mirror: if you see a gap between you finger and its reflection it's a normal mirror, if your finger and its reflection touch it's a transparent mirror (i read this on the internet, if you have a transparent mirror try this so you can tell me if its true, for now on normal mirrors it corresponds to what the trick says)

[@jillianarnold2031]

BabuForTheFriends Actually, that just tells you which side of the mirror is coated. If your finger touches the reflection, the mirror is coated on the front side of the glass. If your finger doesn't touch the reflection, the mirror is coated on the back side of the glass.

[@MysterySteve]

Jillian Arnold ....but the spray needs to be on the backside to reflect the light off of it. Otherwise it basically looks like the non-stick side to aluminum foil instead of a mirror.

[@Lerkero]

Great video, a lot of people don't understand how mirrors work and I think this explains it well, and simply enough.

[@RosheenQuynh]

I really love Glasswing Butterflies and I think it'd be neat to have one crafted with a one-way effect but see-through on one side and the other has color :)

[@SelenaC_anime]

2:37 Well at least you guys didn't say "no space, leave the place."

[@DenorrisBanks]

this was a pretty good episode. you really drew me in. very entertaining and informative.

[@jasiahcisco]

Interesting. I was unaware of the process and wondered many times while watching shows and seeing them in person. Now I know! Thanks guys! Lol

[@nuklearboysymbiote]

Wait, it's not magic?

[@srinjoyray8902]

Never was 🔫🔫

[@pizzadeliverylookingman6094]

Away have been

[@James8hg]

If you shine a light at a one way mirror does it go through or reflect, would it change if you shine it at different sides?

[@theknife69]

I need one in my room if I’m gonna do some experiments on my friend

[@_Bandit88]

During the day, I can see outside through my window, but people outside can't see me, because inside my bedroom is much darker than there. At night, when I turn the lights on it's possible.

[@abeginnerspov5968]

2:06 what kind of reflector reflects light in such a way?

[@gneu1527]

I like how whenever people hear of the term "being watched" they don't even think of a camera, they literally just think of a dude standing somewhere all day and observing you and doing literally nothing about it, only just observing.

[@AchillesBuena]

Me: *confused* maybe ill understand this when im older 2:10 Also ms: ohhh!

[@babbisp1]

One-way mirrors are one of those things you'd expect to only see in sci-fi movies like invisibility or flying cars, but since they actually exist, everyone ignores how freakishly otherwordly they really are.

[@CrakaLakin02]

Im totally overthinking this, but by using one sided mirrors in a cube shape (with the mirrors on the inside) couldn't you make a 4D illusion? assuming there was something inside the mirror cube that emits light?

[@pacomegiraudeau1256]

Search Great Rombicosidodecahedron

[@TheCobraLord]

So for my Film Studies project, I want to use a window that's between two rooms and create the illusion of a mirror on one side. Would this be possible with just regular glass?

[@BrainStuffShow]

+The Cobra Lord If you keep one room very brightly lit and the other very dark, it should work!

[@TheCobraLord]

BrainStuff - HowStuffWorks Perfect, thank you.

[@oliviasonlinediary]

Thank you so much for this information! I understand a LOT more now :)

[@blueckaym]

I wonder if there's a true one-way mirror. The purpose is to trap heat inside, so if should reflect (one-way) at least infrared waves. Is there even such a thing?

[@jasiahcisco]

You should do a video on how the internet actually works.

[@goatmonkey2112]

Use small words so politicians can understand.

[@formdoggie5]

It's a series of tubes. Duh.

[@Mj_26584]

Thanks a lot for this valuable information. Love from Bangladesh❤❤

[@hussalojr5916]

Could this work if instead of a reflective material they used something dark? So like from one side it looks like black glass but the other side looks normal?

[@djSpinege]

i always loved how in the Simpsons "Itchy & Scratchy focus group" you can hear the light switch being turned on. very accurate stuff.

[@suetaylor1127]

But what about in grocery stores where they have one way mirrors to catch thieves?

[@TheMegajupiter09]

Ok now we know. When they put us in interrogation rooms, we would ask the cops to deem the light in our room and increase in the other room. That will be a fair interrogation LOL!

[@amerissa6406]

is there any window film for separations between offices. one way vision for the bosses side and mirror films employee sides. it must be all the time like that. even with light in bosses offices.!! thank you

[@BrainStuffShow]

+Amer Issa Yep! There are a bunch of products like that on the market.

[@amerissa6406]

+BrainStuff - HowStuffWorks thank you. would you recall a brand name?

[@robertbidochon7949]

+Amer Issa You have Llumar, SunTek, 3M, Johnson Window Film and Solar Gard. If you want a one way mirror, they have plenty. It's simply a two way mirror with a layer of tint on top of it.

[@lovedichoreo1529]

1:25 Why would someone place a transparent mirror or two sided mirror typically used in security rooms, police stations and schools for special needs students (again for security/safety issues) in a locker room? Why would one make the office of the coach the office with such a mirror which is looking out directly onto the changing spaces and showers( also used by minors)?

[@lovedichoreo1529]

Why would the school board approve such a remodel?

[@lovedichoreo1529]

Wouldn't contractors, builders or those who did the installation become suspicious during the build when it became apparent what the space would be used for?

[@lovedichoreo1529]

Who drew up the plans? Who approved them? Why?

[@formdoggie5]

Holy fuck--the entire internet wants to know what you are on and where they can get some.

[@kutlesss429]

Wicked cool. Thanks for this.

[@bestamerica]

' 2 way mirror is a so cooool with color LED lights project at home

[@IgorNetoAnimation]

*Lol, time to stalk.*

[@frankj.eichman7358]

This mirror is used on teleprompters as well.

[@Emanstyle2]

This is awesome. You guys rock

[@milesdoodling1054]

Is there any other ways to make a two way mirror? So there can be light in both rooms?

[@Cromatcg]

+Miles Dolding You can place normal window, that way you can see both sides at the same time!. Jokes aside, there are some copper tinted glasses used on external building windows that are slightly more reflective on both sides. That might be what you are looking for.

[@DSFARGEG00]

The Lasser Glass, me lad. It, the room from 1408, Christine, and the truck from Duel have a bowling team. True story.

[@greenshieldgame2004]

What if you were in a room that all around you were window or does mirror window and what you are looking at is a mirror what will you see then ????

[@bryanscreations4783]

The worst haunted mirror is the one in my house. Whenever I look into it there is a monster on the other side >_

[@jaydoggy9043]

Silver nitrate is also no longer used because it's quite dangerous, even able to be absorbed through the skin to cause metal poisoning.

[@merlinmagnus873]

My favorite mirror is one I got out of some laser optics. It's a single mirror but it has a true reflection. If you tilt your head to the right, your reflection tilts its head to its right not your right. Would love to know how that works.

[@merlinmagnus873]

Yes, It's quite odd. Totally useless as a mirror though because my brain is so used to seeing everything in reverse. I would not recommend shaving with this mirror if you value your face.

[@mayamarino52]

the one interesting video my teacher has made me watch

[@arneshpal7702]

0:20 LMAO XD LOL

[@Thenewgreenmaju]

excellent video

[@limerence8365]

One time I was in a supermarket in Switzerland and at the check out desk on the wall there was a simple mirror, but when I pressed my head to it blocking out the light behind me I could see a dark office room. It wasn't very good if I could see through it, simply by looking closely....

[@BrainStuffShow]

That's the way all one-way mirrors work! The mirror coating is partially transparent, so if you get close and block the light around you, you can see through the mirror coating.

[@VitoCorleone786]

I've been asking myself how one-way mirrors work forever. I had no idea it was because of a ceiling lamp 💀

[@-Prakriti]

Give me link of that Mr.bean video

[@lovedichoreo1529]

According to my calculations, Southridge Senior High renovated those locker rooms in 1992 right before Hurricane Andrew, that was 24 years ago Why would a school or school board approve such a renovation?

[@lovedichoreo1529]

Yes, pedophiles have help ladies and gentlemen

[@mushromus7764]

what if you made a ball or cylinmder with this you can see in the ball but not out

[@eliezeririzarry247]

Oh my goodness, this is not what I imagined Jonathan Strickland, the residential and solitary complaint department of Stuff They Dont Want You to Know, would look like. Honestly, I expected more scalp hair and less chin hair!

[@Razgriz85]

Another trick to check if it's a one-way mirror is to put your finger on it, if there's a gap, it's a real mirror, if there's none, it's fake.

[@RealBadGaming52]

Do they actually use them in Cop Stations , imi don't know (never been arrested , just seen it on TV)

[@dondebasis1322]

I still didn't understand 😑

[@im2tired2sleep]

i realized these were real when i could see through the “mirror” at target into an office

[@dah9vandals]

My favorite is rape mirror, the movie occulus is where I got it from. Any one who knows me hears me say rape mirror anytime I see a creepy old mirror. im like oh shit its rape mirror and its going to rape then kill you while you watch!!!

[@davidwilson8800]

I read mercury was actually the first metal used to make mirrors

[@tracycolleenlimoges5161]

I had many experiences that seemed....well you try to figure it out please...you seem like you don't limit your thinking...You use logic...than consider the other. I too accept the unknown and have accepted with love many levels of expandsions even altered states with understanding...As experience has gifted and shaped me into a beautiful human that is of a kindred spirit that is of love and light.. I will shred's with you later..til next time.. God Bless you! Tracy Limoges

[@007JAKICA]

QUESTION if i have a lamp in detective's room pointed to criminal's room, how much of light will pass from one room to another?

[@SandunDev]

watvid1 It's always the same. They never say it right

[@azura3479]

+Sunshine So because our English has evolved differently from yours then we're stupid? Lol ok

[@azura3479]

I can agree that we really need to switch to the Metric system... measuring by tens is much easier than "random" numbers. I would try to explain why we actually use it, but I'll keep it short and sweet: after breaking free from British rule, we didn't want anything to do with Britain. As for saying "aluminum" it's really only because of the mispronunciation of "aluminium" that stuck to American English. (I'm not trying to argue, I'm just pointing out the reasons why we have these things to slow the belief that we're arrogant)

[@axlthesnake]

watvid1 In 1808 Sir Humphry Davy, the British chemist who discovered the metal, named it “alumium.” With just one “i” and an “ium” ending, it straddled the two competing versions we have today. Four years later, however, Davy changed his mind and gave the metal the name “aluminum” (yup, the one-“i” American version).Jun 26, 2008 The Grammarphobia Blog: "Aluminum" vs. "aluminium" Anymore information to prove the UK wrong.
