Riddle: What goes up and down, but cannot move? Let’s think about this.
This one is too short and direct that you assume it’s going to be easy to know the answer… Let’s start brainstorming! Some of the things that come to my mind are elevator, planes, helicopters… Yes, they go up and down but they also move, don’t they? You can not keep an elevator fixed and expect it to carry people from the bottom floor to the top floor. It just has to move!
So what is the thing that is fixed but also, possibly, carries you from bottom to top? A staircase! They go up and down, but you’re the one moving. You go up or down the staircase. It is fixed. You move. Blew – my – mind!
Answer: A staircase.
