In a Rube Goldberg you have to have some steps. Our assignment was to have at least 8 steps. But William and I are making one that is 12 steps long. We haven’t made all of the steps yet but we have made a few. One of the steps that we have made is where a little robot called an Ozo Bot follows a line once a domino is pulled away and hits a domino. Another step is where a pool ball rolled down half of a maze made by Lincoln logs and that pool ball hits another one which finishes the maze. These are two steps that we have tried out and they worked.
These are links to the videos of them:
I thought that this blog postwar really good. It listed all the Rube Goldberg requirements and it had links.
