Similar to convex mirrors used in some parking areas, these mirrors are useful because they can be placed on the ceiling and near corners while expanding the field of view due to their convex shape. Because of this, they are often used for seeing behind people while being in front of them (with the mirror perched high on the wall behind a line of people), looking around corners, and behind yourself. Convex mirrors basically expand your view like mirrors in a car and can be useful for spotting potential thieves without even having to look directly at them. The use of these mirrors is somewhat limited because they often have blind spots and the person being spotted on the mirrors can look back into it to see if anyone is observing them.
A kaleidoscope is composed of two or more mirrors laid lengthwise inside a tube, in addition to colored beads or other small objects reside in the tube's larger end. Light passes through this end, hitting the colored objects inside the rotating compartment. Any random configuration created in the falling of the colored objects reflects in the mirrors, making beautiful symmetrical patterns. Rotating the compartment moves the objects, creating a different image than previously seen.
Ancient humans discovered that they could see their reflections in shiny metal. They began to polish metal disks on purpose and make mirrors. This was the sort of mirror people had for thousands of years until they learned how to make glass. Then, scientists learned to coat the back of a piece of glass with silver to make an even better reflection.
