In preparation for students building Rube Goldberg Machines, I like to show a couple clips peppered into each class to show students what Rube Goldberg machines are and what they can look like. I use both professional clips and student developed film clips. Here are some of my favorite professional clips:
This Too Shall Pass, by OK Go
Page Turner (The making of Page Turner and other Rube Goldberg Machines by Joseph Herscher)
Doble Fibra ad (Double Fiber)
Fresh Machine ad from Target
Additionally, try this Rube Goldberg Game called Goldberger To Go.
