#1 World’s first-ever mirror

Even before the invention of the world’s first mirror, people of ancient times used to see their reflections in small lakes or ponds in streets. Well, water movements might likely have distorted their images, but we’re sure they wouldn’t mind it.

The earliest mirror to be invented was in 8000 bc; that was too out of polished obsidian, volcanic glass. Later, roughly between 4000-3000 BC, mirrors manufactured out of copper were introduced in Mesopotamia (present Iraq). It was not until 1000 years later when people in South America started making mirrors out of polished stones.

Wow, it seems mirrors have a pretty exciting history! 


#2 A gigantic Salt flat in bolivia serves as the world’s largest mirror.

Who hasn’t heard the very famous line ‘mirror, mirror on the wall’ but, today we’re here to introduce to you: mirror, mirror on the floor. Yes, you heard that right! Salar de Uyuni, a salt flat located in Bolivia’s southwest corner.

This massive salt flat covers an area of 4000 square miles.  So, when rainwater or water from nearby lakes accumulates onto the surface of Salar de Uyuni, this gigantic salt flat transforms into a lake. Owing to this thin water layer, the salt flat becomes tremendously reflective, turning it into the world’s most giant natural mirror.

This fact might go down as the creepiest one you have heard about mirrors as of late. For many years, people have stated that if you stare at your reflection in a mirror long enough, a strange illusion is triggered. Gazing into the mirror for more than 10 minutes can cause you to see hallucinations, some being distortions in your face, faces of animals like pigs, cats, and even faces of your deceased relatives.

As insanely terrifying it sounds, it is hard to believe. You can try it yourself.

  • Sit a few inches away from a mirror in a dimly lit room, light enough to see your reflection in the mirror.
  • Now stare at yourself in the mirror for 10 minutes.

What do you see? We’re curious to know!


#4 Mirrors can reflect sound

By now, you might have had the concept of mirrors reflecting light only. But did you know that mirrors can reflect sound too? Quite interesting, right?

Sound mirrors are innovative devices used to reflect and focus sound waves. Such mirrors are tagged acoustic mirrors. To demonstrate the phenomena of mirrors reflecting and focusing sound waves, parabolic acoustic mirrors called the whisper dishes are used in many science museums.

In such museums, parabolic dishes are separated by a 10ft distance. A person standing close to one parabolic dish can hear the 2nd person whispering near the other parabolic dish despite the considerable distance between the dishes. It seems mirrors have ears too!

If only that weren’t enough to blow your minds away; it was During World War 2, before the invention of radars, Britain actually used the large parabolic acoustic mirrors to detect the approaching enemy air crafts. You thought you understood mirrors; well, we used to have the same belief!

#5 Mirrors can not only reflect light but can split it too. 

Yes, mirrors are not only the reflectors of light, but they are capable of splitting it too. Because of this fascinating nature of mirrors, they form a part of several beam splitters. In beam splitters, two triangular prisms are glued together at their bases. The beam splitters reflect half of the incident light rays, and the rest half continues as it is.

Another version of beam splitters known as the dichroic mirrored prism splits the incoming light rays into two different beams. Similarly, the trichroic mirrored prism splits the light beam into three beams of different wavelengths. Such beam splitters nowadays are being used in modern 3-CCD cameras.

Mirrors are valuable tools, after all!

#6 Mirrors on the moon

Who could have thought that an object you gaze at regularly is used on moons? Incredible, isn’t it? Let’s dig into more information.

Apollo missions, Apollo 11,14, and 15 left retroreflectors on the moon, which are basically panels of mirrors. These retroreflectors are still being used to measure the distance between the Moon and the Earth. From the Earth, the researchers shoot a laser at the retroreflectors, and these panels of mirrors will reflect the laser beam along the same pathway.

Putting some maths into action, if the return trip time of the photon is multiplied by the speed of light and divided by 2, you can actually calculate how far the Moon is situated from the Earth.

So, the next time you and your friends appreciate the beauty of the moon, you can surprise them with this interesting fact. It’ll definitely get you some high praises!

When we humans gaze into the mirror, we recognize our reflection right away. For us, it’s not a big deal to recognize ourselves in the mirror; in fact, to us, it seems pretty natural. However, psychologists seem to think otherwise.

According to several renowned psychologists, this requires self-awareness which is considered a complex aspect of consciousness. But the real head-scratcher here is: Are animals self-aware?

Some animals like orangutans, chimpanzees, gorillas, dolphins, elephants are self-aware, meaning that when a mirror is brought close to them, they tend to recognize their reflection in mirrors. How impressive! 

With that said, there are other animals like dogs who can not comprehend their own reflections and act in peculiar ways seeing their faces in mirrors.


 Below are the two creepiest facts listed about mirrors—ones that can possibly make you avoid looking in the mirrors at night. So, continue at your own risk!
