Conceptual physics students spent a week in the Black Box Theater creating Rube Goldberg machines that perform a simple task through an elaborate set of chain reactions. Each simple machine performed a task that results in a long string of actions that lead to an ultimate result.  These groups chose ringing a bell and popping a balloon as their desired outcome.
