That's Why Elevator Doors Have a Tiny Hole

Описание: Today, there are more than 1 million elevators just in the US, carrying people higher and lower every day. All these elevators travel about 1 and 1/2 billion miles per year and move around 18 billion passengers. You might think that you know everything about this vertical kind of transport. But, let's say, have you ever wondered why elevator doors have small holes in them?

Something must have gone wrong with the equipment, or there has been a power failure. In this case, getting out won't be an easy feat! That's why all you can do is to wait for an elevator mechanic. Finally, they turn up, but what next?
