Have you ever been in a dressing room or bathroom and felt like someone was watching you? Mirrors are found in very common places. They’re in hotel rooms, bathrooms, dressing rooms, toilets, etc.; they’re pretty much everywhere. But do you know if it’s a mirror or 2-way mirror (you can’t see them, but they can see you)?
A two-way mirror is a piece of glass coated with a substance called micro pane. If standing on the treated side, you see your reflection. The untreated side looks like a tinted window. But can you tell the difference between a 2-way mirror and a regular mirror?
Well, there’s a simple trick that determines whether you’re looking at a mirror or 2-way glass. It’s called a fingernail test.
Begin by placing the tip of your fingernail against the mirror. If you see a GAP between your fingernail and the mirror, you’re safe, it’s a genuine mirror.
If there isn’t a gap, and your fingernail is directly touching your reflection, there’s a high possibility it’s a two-way mirror.
Remember: “If there’s no space, leave the place”
The next time you’re unsure if you’re looking at a mirror, use this simple test and you’ll know within seconds!
