Putting a stamp on a postcard should be relatively easy, right? One must simply pick, lick, and stick. But for Melvin the Mini Machine, the task couldn't be more belabored--and amusing!

Named after Pulitzer Prize-winning inventor and cartoonist, Rube Goldberg contraptions set off chain reactions to complete a simple task.

Those complicated contraptions have inspired others to make their own versions, check out a couple after the jump.
