How To Check For Two-Way Mirrors
1.Examine the mirror
The first and foremost precaution you should do when you’re in a private place with a mirror is to examine it. Check how the mirror was installed. Was it hung on the wall,adhered to the wall,or embedded on the wall itself?Two-way mirrors are often installed flush with the wall.
2.Knock on the mirror.
Try tapping on the mirror with your knuckles.Since it’s been placed on a wall,normal mirrors will sound dull and flat,like thud,when knocked on.On the other hand,two-way mirrors will sound hollow because there’s a room on the other side.
3.Peer through it.
If it is a two-way mirror,it’s possible for you to see through the other side if you try to peer through the glass.Press your face to the mirror and try to block out as much light as possible by cupping your hands around your eyes.You should be able to catch a glimpse if there is a room on the other side.
4.Use a light.
Shine some light on the mirror using a flashlight or the flashlight from your phone.Place it very close to the mirror.Turn off the lights from where you are if possible so that only your flashlight is shining.The room on the other side will most likely be illuminated and seen if you do this and if it is a two-way mirror.
5.Fingernail test.
Out of all the possible ways to test a two-way mirror,the fingernail test is the most inaccurate. However,it can still provide some insight.Everyday mirrors are often second surface mirrors,meaning there’s a second layer of glass.Thus,if you press your finger against a second surface mirror,you’ll see that your finger doesn’t touch its reflection.If your finger can touch its reflection,then the mirror could be two-way.
