Rube Goldberg machines are always a fan favorite around here. They truly embody the concept of over-engineering, and are an entertaining departure from what we normally cover on Hackaday.

Back in February, engineering students from two on-campus professional associations at Purdue University teamed up to construct a world record-setting Rube Goldberg machine. Their entry in the Purdue Regional Rube Goldberg Machine Contest not only won them the regional title, but also potentially put them in the books as creating the most complex device of its nature.

Their contraption was dubbed “The Time Machine” and acts out events in our planet’s history. It starts with the big bang, moving through various other time periods, including the stone age, ancient Egypt, and the medieval era. It also makes several stops in more recent times, including World War II and the Cold War, before self-destructing at the Apocalypse.

All told, the machine incorporates 244 steps to water a plant, which is 14 more than the previous record holder. Continue reading to see a video that highlights some of the machine’s more interesting features, and be sure to check out these Rube Goldberg machines we’ve covered in the past.
