Above, an example of a Rube Goldberg cartoon. These are the inspiration for an engineering student competion. This year, it took six months and 125 steps for a team of Purdue University students to win the 22nd annual Purdue Rube Goldberg Machine Contest. But this event is only a regional run up to the big national contest, which will also be held at Purdue but later this year.
The Rube Goldberg Machine Contest is named after cartoonist Reuben Goldberg, the spirit of whose work inspires the contest's weird machines and crazy mechanism. For 55 years Goldberg's award-winning cartoons satirized machines and gadgets which he saw as excessive. His cartoons combined simple machines and common household items to create complex, wacky, and diabolically logical machines that accomplished mundane and trivial tasks.
At this year's regional contest at Purdue, the winning machine was built by the local Society of Professional Engineers and incorporated a bouncing water balloon, a fireman action figure fleeing a fire and weights attached to a spinning bicycle wheel
The job it was designed to do was to shred five pieces of paper but to do it in the most convoluted and complex manner possible. The winners will go on to a national contest in April.
The five pages destroyed was a short "History of Technology" paper and was ultimately destroyed by a fire-breathing dragon.
National Competiton Finals coming up
The 2006 National Rube Goldberg Machine Contest is coming up. It will be at held 10:30 a.m. to approximately 1:00 p.m. April 1 in the Purdue University Armory.
The events are free and open to the public.
All machines will be required to individually cut or shred five sheets of 20 pound, 8 1/2-x-11-inch paper in a minimum of 20 steps.
