When rube goldberg started, Miss Cooper said to get into a group of two, three, four or being a solo, me and my friend Alex decided we would be partners a week before Ms. Cooper told us about it. We knew we would do good because we had both done rube goldberg before at a camp. We were thinking about adding a third person. But then we realized we would have to find a time that worked for everyone. So we decided it would be easier as a duo. Me and Alex decided that we would work at my house because it had a big open room that is empty and that no one in my family used. We also decided that we would work every Tuesday and Thursday before hockey practice. We decided to use for our materials dominoes, hot wheels tracks, match box cars and a hockey puck.
