The document describes a study on how the design of a water bottle can influence hydration. It presents initial prototype designs, a revised design, trial methods that included quantitative measures of water consumed and subjective ratings of thirst awareness, quantitative results showing increases in water consumed and bottles fully emptied, and plans for next steps. The goal was to explore how dynamic tactile engagement with a water bottle's surface through a simple design change can promote greater hydration and somatic awareness of one's body and needs.
