A Rube Goldberg machine is a device deliberately over-engineered to perform a simple task through elaborate steps. You may remember attempting to make one of these in elementary school or seeing one on Bill Nye the Science Guy or Beakman’s World. These are fun and elaborate contraptions that are all about chain reaction and making the different parts come together at just the right time and in just the right way to get to the end task.
The real draw of a Rube Goldberg device is watching it in action. Creators usually quite literally add as many bells and whistles as possible to their machine for entertainment purposes. "The Time Machine," created by the Purdue Society of Professional Engineers/Society of Professional Hispanic Engineers, takes the visual entertainment aspect of these machines to a whole new level. The contraption goes throughout all of history, depicting many major events—even the supposed 2012
The machine starts viewers out with the dinosaurs, the Ice Age, and moves straight into civilization, major wars, the invention of the record, all up to the near future. Besides being an amazingly entertaining device, it also holds the record for most steps taken in a Rube Goldberg device: 244. Below is video footage of the fantastically clever device in action!
