What is it that goes up and goes down but does not move?
Common Wrong Answers
“An elevator”
An elevator moves up and down physically, which contradicts the riddle's requirement for something that does not move.
“A balloon”
While a balloon can rise and fall, it does so by moving through the air, making it an incorrect answer.
“A staircase”
A staircase allows people to go up and down, but it itself is a physical object that does not change position.
