The last week had a lot to do with escalators. I’m currently in Coronado, a part of Panama, for my winter break. While browsing the Internet I came across a video that is allegedly of people trying an escalator for the first time. At first I found it kind of funny, but then I tried to understand how what I saw was possible. I mean it’s not that hard to ride an escalator, I think.
I thought of two different reasons: the handrail couldn’t support much mass and the handrail was moving at a different speed than the steps. If you watch the video carefully you can see that the passengers only start to fall when they grab onto the handrail. You can also see that the handrail moves slower than the steps so the people fall backwards.
