It has been noticed that People in Odenplan, Stockholm were much more using the escalators than the stairs in the subway station. The local group conducted an experiment to see if they could make people use the stairs too by adding in a bit of fun! They came up with an idea of Piano Stairs and it seems to have worked out well that you can notice through this video.
The Piano Stairs actually produce real piano-like notes when the keys-(the stairs in this case) are stepped on… Check out the video above to see how the fun theory change people’s behavior, people enjoying the music and getting some workout too.
