Rube Goldberg machines' purpose is to indirectly perform a task by creating a series of simple tasks. They relate to science because throughout the process there are several transfers of energy. Each complete step is a different transfer of energy and all steps have potential energy before the machine starts.
Our machine's purpose is to pour sprinkles on top of a cupcake. We chose this accomplishment because we wanted the machine to do something fun and creative that reflects how we imagine a Rube Goldberg.
