How To Detect Two Way Mirrors

“When we visit toilets, bathrooms, hotel rooms, changing rooms, etc. How many of you know for sure that the seemingly ordinary mirror hanging on the wall is a real mirror, or actually a 2-way mirror i.e., they can see you, but you can’t see them. There have been many cases of people installing 2-way mirrors in female changing rooms or bathroom or bedrooms.

It is very difficult to positively identify the surface by just looking at it. So, how do we determine with any amount of certainty what type of mirror we are looking at?


CONDUCT THIS SIMPLE TEST:

Place the tip of your fingernail against the reflective surface and if there is a GAP between your fingernail and the image of the nail, then it is a GENUINE mirror.


However, if your fingernail DIRECTLY TOUCHES the image of your nail, then BEWARE, IT IS A 2-WAY MIRROR! (There is someone seeing you from the other side). So remember, every time you see a mirror, do the “fingernail test.” It doesn’t cost you anything. It is simple to do.This is a really good thing to do. The reason there is a gap on a real mirror, is because the silver is on the back of the mirror UNDER the glass.
Whereas with a two-way mirror, the silver is on the surface. Keep it in mind! Make sure and check every time you enter in hotel rooms. May be someone is making a film on you. “


This one is false. Here are few tips how you can detect real one:

1. Realize that a popular email about two-way mirrors you may have received is a hoax. It is simply an urban legend that has gained credibility as it has gone from one recipient to the next. You can check suspect stories you hear against the urban legends database at Snopes.com.

2. Understand that a two-way mirror is specially treated glass that allows light to pass through in both directions, but which also reflects light back into the room. If lights are off on one side of the mirror and on in the other, those on the bright side will see a reflection and those on the dark side will see through the glass.

3. Know that because they function as windows, two-way mirrors are generally set into the wall; they are not hung on a wall. If the mirror is not flush with the wall, it is most likely not a two-way mirror.

4. Test the mirror. Cup your hands around your eyes and place your face next to the mirror. If it is a two-way mirror, you will be able to see something on the other side—unless there is absolutely no light on that.

5. Turn out the lights. The two-way mirror only works if light is more intense on one side. With the lights off, you will see through a two-way mirror. It may take a few moments to detect the mirror as your eyes adjust.

6. Tap the mirror. A two-way mirror will produce a hollow sound like a window because there is no backing on the other side. A regular mirror will sound dull.
