The world’s fastest elevator is in Shanghai Tower in China. Tall buildings need fast elevators. Otis invented the first elevator in 1857. Sometimes elevators can stop and people get stuck. Elevators are important because it would take too long to get up stairs and down if you had to walk.
Riley, I’m glad you enjoyed learning about elevators. I did too. I was amazed at all of the cool kinds. It would be difficult to have to walk up so many flights of stairs. I guess we can thank Otis for making life easier for us.
