The 31st annual Purdue Regional Rube Goldberg Machine Contest will take place this Saturday at the Purdue Armory. The contest was inspired by Rube Goldberg, a cartoonist famous for depicting complex gadgets that perform one simple task. Every year, the contest challenges its contestants to create a machine that will perform multiple steps to complete one task; these tasks could include things such as putting a stamp on an envelope or screwing a lightbulb. This year's task is to design a machine that will hammer a nail in 20 steps or more.

The competition is sponsored by Theta Tau, the professional engineering fraternity on campus. A team from the Purdue Society of Professional Engineers and the Society of Hispanic Professional Engineers won last year with a machine that inflated and popped a balloon.

The winners from this regional competition will move on to the national competition that will take place at noon on March 30 in Columbus, Ohio, at the Center of Industry and Science.

The contest will begin at 10:30 a.m. this Saturday in the Purdue Armory. Doors will open at 9:30. Admission is free and open to the public.
