This Video Reveals Why Most Elevators Have Mirrors Inside Them
Elevators have a fascinating history that goes all the way back to several hundred years before Christ. The first elevators were called hoists and were human, animal or water-powered.
However, modern elevators as we know them today were first recorded in the 1800s. And during that time, a lot of tweaks and adjustments have been made to enhance their functionality.
They went from steam-driven to hydraulic power.
The first electric elevator was built in 1880, and the first commercially successful elevator was released in 1889. And also, many improvements in elevators were made during World War II.
Today, we can't imagine a tall building that doesn't have an elevator, but maybe the most curious thing about elevators is that most of them have mirrors. Have you ever wondered why that is?

We won't reveal why most elevators tend to have mirrors. All we'll say is that the reason why is a rather interesting one. Watch the video to find out more.
