We investigate an unconventional user interface (UI) material, water,and how applying it to a finger-touch based input affects the userexperience (UX). We compare the use of touchscreen, mechanicaland liquid covered sliders, and three different approaches of howwater is applied to the surface of the slider. The salient findings ofour user study (n=25) show that liquid changes the perception ofthe slider control making it more hedonic and experiental. Wheninteracting with water, users prefer larger and more free-formgestures, and factors such as depth and temperature of the liquidaffect the experience. Our work provides information for interactiondesigners focusing on user experience, unconventional materialsfor interactive systems, aesthetics, and calm UIs
