A two-way mirror is often called a "one-way mirror" by members of the general public. The misconception is that such a mirror acts as a mirror from one side, and acts as a window (letting light through) from the other side.

How to determine if a mirror are 2 way or not (Not a Joke!), Not to scare you, but to make sure that you aware. Many of the hotels and textile showrooms cheat the customers this way & watch privately.



HOW TO DETECT A 2-WAY MIRROR:

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 does not cost you anything. It is simple to do. This is a good thing to do.

The reason there is a gap on a real mirror, is that 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.

You got a good point here Marlon, but this trick is also common to those perv's that installs two-way mirrors and they found a way to resolve this "finger-point test". If the mirror is installed "on" the wall, you can test it a see if it is a true mirror, but, if it is installed "in" the wall, meaning nakapantay sa wall, then the finger test will do you no good. You see, these perv's really invest on this "hobby" or should i say sickness and they put a transparent glass on top of the two way mirror. So even if you point your finger nail on the mirror, you will still see the gap between your nail and its image. And that do the trick. So next time you go to a hotel/motel, best is you turn off the lights before changing clothes and running naked or before you start the action with your partner.

oo nga noh... mga manyakis na yan... hehe... tnx for the info...

According to the folks in Mirropane's technical support group, you can
use these factors to your advantage by pressing your eyes up against the
mirror and cupping your hands around them (to block out the light from
the room you're in): if you're truly dealing with a transparent mirror,
you should be able to see at least a little something of the open area
behind it. Also, rapping on the mirror should provide an aural clue:
ordinary mirrors have backings and are usually placed against walls, so
rapping on them will generally produce dull thuds; transparent mirrors
and set into walls with open areas behind them, so rapping on them
should produce much more open, hollow sounds. These methods of detection
are more reliable than the fingernail test and should be preferred to
taking a chance on getting arrested for property damage after tossing a
chair through a perfectly normal mirror misjudged via less accurate
means.
