The Piano Stairs Experiment
Volkswagen's initiative called 'The Fun Theory' wanted to prove that people's behaviour can be changed for the better by making boring, everyday tasks more fun. In this experiment in Stockholm, Sweden they installed musical piano steps on the staircase of a subway station to see if more people would choose the healthier option and use the stairs instead of the escalator.
The results showed that 66% more people took the stairs than usual that day, because we all like a little fun don't we? At heart we are like kids in a playground, so making our cities more fun can make us all happier, fitter and healthier.
