How to determine if a mirror is 2 way or not.
Not to scare you, but to make sure that you aware. This was passed on by a police woman who travels all over the US and gives seminars and techniques for house wives, business women, executives. Many of the hotels cheat the customers this way & enjoy while the couple enjoy their honeymoon in their rooms.


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?


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.

    I’ve been unable to track down any reliable source (policewoman or otherwise) of this information, nor does the NYPD have anything to do with this tragically misinformed notice.

    Can you really tell if the mirror you’re staring at hides a pair of leering eyes using just your fingernail? The simple answer is no. All you can tell from the “fingernail test” is what type of mirror you’re looking at. Some mirrors (called second surface mirrors) have the reflective surface on the “bottom” of a sheet of glass, so you look through the glass to see it, thus creating a gap. The other type of mirror, a first-surface mirror, puts the reflective surface on top, thus no gap. However, this type of mirror is more expensive and usually only used where precision reflections are necessary.

    The 2-way mirror discussed above is not a mirror at all, but rather a window made of specially treated glass that uses varying intensities of light to mimic the reflective surface of a mirror. When light is bright on one side, and darker on the other, the glass will look like a mirror from the brighter side. A good example is a mirrored office building. During the day, you can’t see into the building, but at night, you can clearly see into any lighted office. If the light intensity is the same on both sides of the glass, it will appear to be just a normal piece of glass.

    If you really want to know if the mirror you’re using is 2-way, just turn the lights off. Of course, you might look mighty silly standing in a dark bathroom trying to see the little people in the mirror, so hope nobody walks in on you. Break this chain!
