Rube Goldberg

I recently became obsessed with / transfixed by various Rube Goldberg machines found on Youtube. If you didn't already know, Rube Goldberg machines are "complex devices that perform simple tasks in indirect, convoluted ways". Just like life really. These were my favorites. Judging by the Youtube comment board, they are advertising a kid's TV show. What can't the Japanese do with intricate precision?
