This paper presents "the DataBuzz Project." "DataBuzz" is a high-tech, mobile educational lab, which is housed in a 13-meter electric bus. Its specific goal is to increase the data literacy of different segments of society in the Brussels region through inclusive and participatory games and workshops. In this paper, we will explore how to carry out practical data literacy initiatives geared to the general public. We discuss the different interactive workshops, which have been specifically developed for "DataBuzz." We highlight the background, design choices, and execution of this large-scale data literacy initiative. We describe the factors that need to be taken into account to reach successful execution for such an ambitious project and the actions undertaken to become a long-term, sustainable solution. Throughout the article, we use the Data Literacy Competence Model as an analytical lens to analyse individual projects on data literacy and "DataBuzz" as an integrated project.
