TikTok has gained immense popularity among teenagers, offering access to numerous user-generated content. Notably, food videos have emerged as a prominent theme on this short-form video social platform. The casual and enjoyable nature of short food videos on TikTok belies their potential influence on one of teenagers' most immediate and regular health practices--eating. Understanding how teenagers interact with these videos, their subsequent actions, and the resulting impact on their food practices and eating habits have the potential to provide insight into their broader lifestyle choices and their interactions within their social circles, including parents, friends, and other people online. By examining how teenagers use TikTok food videos online and offline, we gain a deeper understanding of the intricate relationship between social media, teenage lifestyle, and social dynamics surrounding food practices. In this research, we conducted 15 semi-structured interviews with teenagers aged 13 to 19, investigating their consumption of TikTok food videos and the actions inspired by them. By examining the multifaceted influence of TikTok food videos from a temporal perspective, this study contributes to the reflections of teens' use of TikTok food videos and their inspired food practices in the short and long term, online and offline. We propose design and theoretical implications to support teenagers' health. These insights have the potential to extend to various contexts, helping educators, policymakers, and designers in fostering healthy lifestyles among teenagers. 

Purpose This paper aims to explore what design aspects can support data visualization literacy within science museums. Design/methodology/approach The qualitative study thematically analyzes video data of 11 visitor groups as they engage with reading and writing of data visualization through a science museum exhibition that features real-time and uncurated data. Findings Findings present how the design aspects of the exhibit led to identifying single data records, data patterns, mismeasurements and distribution rate. Research limitations/implications The findings preface how to study data visualization literacy learning in short museum interactions. Practical implications Practically, the findings point toward design implications for facilitating data visualization literacy in museum exhibits. Originality/value The originality of the study lays in the way the exhibit supports engagement with data visualization literacy with uncurated data records.
