Rube Goldberg machine

A Rube Goldberg machine is a deliberately complex contraption in which a series of devices that perform simple tasks are linked together to produce a domino effect in which activating one device triggers the next device in the sequence. The expression is named after American cartoonist and inventor of such contraptions, Rube Goldberg (1883–1970).

Over the years, the expression has expanded to mean any confusing or complicated system. For example, news headlines include "Is Rep. Bill Thomas the Rube Goldberg of Legislative Reform?" and "Retirement 'insurance' as a Rube Goldberg machine".

Rube Goldberg's cartoons became well known for depicting complicated devices that performed simple tasks in indirect convoluted ways. The example on the right is Goldberg's "Professor Butts and the Self-Operating Napkin", which was later reprinted in a few book collections, including the postcard book Rube Goldberg's Inventions! and the hardcover Rube Goldberg: Inventions, both compiled by Maynard Frank Wolfe from the Rube Goldberg Archives. The "Self-Operating Napkin" is activated when soup spoon (A) is raised to mouth, pulling string (B) and thereby jerking ladle (C), which throws cracker (D) past parrot (E). Parrot jumps after cracker and (F) tilts, upsetting seeds (G) into pail (H). Extra weight in pail pulls cord (I), which opens and ignites lighter (J), setting off skyrocket (K), which causes sickle (L) to cut string (M), allowing pendulum with attached napkin to swing back and forth, thereby wiping chin.

The term "Rube Goldberg" was being used in print to describe elaborate contraptions by 1928, and appeared in the Random House Dictionary of the English Language in 1966 meaning "having a fantastically complicated improvised appearance", or "deviously complex and impractical."
