How a Rube Goldberg Coffee Machine Works - Fun Engineering Diagram #3055647 (License: Personal Use)

This black-and-white line drawing depicts a multi-stage Rube Goldberg device where a ladybug initiates a cascade of mechanical actions-including rolling balls, tipping trays, and lever-activated valves-to ultimately dispense coffee into a cup. The sequence ends with a three-star rating plaque, suggesting quality or satisfaction. Each component is stylized with exaggerated motion lines and expressive details to emphasize cause-and-effect storytelling.
