Gloriously complexified necktie-tying machine

Seth Goldstein's Why Not machine is a glorious Rube Goldberg device that can tie (and untie) a necktie. It's a kinetic sculpture, slow and beautiful and inefficient in a way that can only be called artistic. It's headed for exhibition at the Franklin Institute Science Museum in Philadelphia. Its inventor, a retired engineer, revels in its unuselessness: "That's not something you can economically justify, but if you're a retiree, you don't have to worry about that anymore. I'm free!"

World's largest K'Nex ball machine

K'Nex master Austron is constrcting the world's largest K'Nex ball machine. It's located at Bloomington, Minnesota's The Works museum. Austron says:

The machine stands 23.5 feet tall and 40 feet long, and contains over 100,000 pieces. It has 2 lifts, 3 motors, and 8 paths, including a 20 foot free-fall, an 8 foot tall big-ball-factory spiral, and a 60 foot long path which hangs from the ceiling. It takes 3 and a half minutes for a ball to climb to the top of the tallest tower.

Rube Goldberg machine that integrates freerunners with lots of guts, little regard for own safety

Freerunner Jason Paul and friends got (a presumably large amount of) money from Red Bull to construct a building-scale Rube Goldberg machine that integrated several parkours at various stages of its operation, mixing the improbable action of inanimate objects with the improbable (and breathtakingly dangerous) actions of human lunatics.

Robotic Lego ball contraption to beat them all

Akiyuky on YouTube has uploaded a 7 minuted video overview of her or his astounding Lego Ball Contraption, a robotic rube goldberg device in 17 modules, each more fiendishly clever than the last. The accompanying blog (in Japanese) has lots more detail. But honestly, you can just sit agog for seven glorious minutes and soak it all up without having to try and parse out Google Translate's rendition of Akiyuky's explanation.

Rubegoldbergian light-switch cover


Etsy's GreenTreeJewelry makes these whimsical, rube goldbergian light-switch covers that let you toggle the switch by means of a delightfully superfluous mechanism: "This light switch cover is completely functional. Levered handle toggles back and forth, turning on and off light switch."

Record-breaking Rube Goldberg inflates, then pops balloon in 300 steps

Purdue's Society of Professional Engineers set a new record for rubegoldbergery with a 300-step balloon-inflater/popper. As magnificent as the machine itself is, the best part of this video is unquestionably the roar of the crowd.

WEST LAFYETTE, Ind., USA--The Purdue Society of Professional Engineers team smashed its own world record for largest Rube Goldberg machine with a 300-step behemoth that flawlessly accomplished the simple task of blowing up and popping a balloon - setting the new world record for the Largest functional Rube Goldberg machine, according to World Records Academy.

Over-elaborated rubegoldbergian steampunk corkscrew

Gramturismo sez, "A maker in Scotland has created an elaborate, steampunk style hand cranked corkscrew." It's quite an amazing gadget -- talk about thoroughly solving a problem!

Photography-themed Rube Goldberg machine

Canada's 2D Photography created this amazing Rube Goldberg device out of photography stuff of all descriptions, and made the whole thing so witty and fun that I watched it twice in a row.
