The document describes a liquid tree project that aims to reduce water waste in the home by encouraging more sustainable shower habits. It works by visually displaying the amount of water wasted during showering through the rise and fall of liquid in a decorative tree-shaped structure. Users can interact with the device by controlling switches to move liquid between layers and keep a desired tree pattern. The goal is to make users aware of their water usage and motivate them to take shorter showers through gamification and an aesthetic design.
