In Japan, there's a children's educational program called PythagoraSwitch. The majority of it is a Sesame Street-style puppet program, but there are fantastic interludes with Rube Goldberg machines. Let's watch those!

Above, you can see what's supposedly all of the show's Rube Goldberg machines. My kids have grown up watching this program each morning, and the highlight for them (okay, me) are these incredibly inventive contraptions. They never cease to amaze and impress.
