Two Way Mirrors

What are Two Way Mirrors?

Two Way Mirrors are just like normal mirrors, only to you. They reflect back light only from the side you look at it. From the other side, it's just a plain glass, you can look through them!

What's the big deal with Two Way Mirrors?

Two Way Mirrors are illegally used in toilets, changing rooms, hotel rooms etc. They are usually attached to the wall with the reflecting surface facing us. They look like ordinary mirrors to us but transparent from the other side. People spy on the public in such a way.

How do we detect Two Way Mirrors?

We cannot detect Two Way Mirrors by simply looking at them. Here is a simple test to identify a two way mirror :

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 Two Way Mirror! 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. Maybe someone is making a film on you.
