how to detect a 2-way mirror??
when we visit toilets, bathrooms, hotel rooms, changing rooms, 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. ppl can see you from the other side, but you can’t see them)
there have been many cases of ppl installing 2-way mirrors in female changing rooms. it is very difficult to positivily 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?? just conduct this simply 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, for it is a 2-WAY MIRROR!
the reason there is a “gap” on a real mirror, is because the silver is on the back of the mirror UNDER the glass. as a two-way mirror, the silver is on the surface.
so remember, every time you see a mirror, do the “fingernail test”. it doesn’t cost you anything. it is simple to do, and it might save you from getting “visually raped”!!
