The user THEREWASHOMEWORK? posted on 3 17 14 about the difficulties and frustrations of trying to plan the makings of a Rube Goldberg machine. I agree that it is very difficult to plan how things will react with one another exactly, and so it is best to make the machines with an open mind and a lot of patience. I also agree that OK GO was very creative in the making of their music video, and it's clear that their team of helpers seen at the end of the video worked very hard on the giant machine, and was very happy when the filming was over and they had succeeded. I can't say I blame them, physics can be hard sometimes, but in the end it does give you a great sense of acomplishment.
