The first time Jonny, Ian, and I met for Rube Goldberg we had a big problem! How are you supposed to combine our house hold items into a Rube Goldberg? We started by making a sketch. Dominoes into Jenga clocks into more dominoes into Rubikub into a marble track. We used google drawings to make our sketch. After we made our sketch, Jonny and I searched the house for any more objects that would be useful. We found none but started to assemble our Rube Goldberg.
Maybe add your sketch or a link to your sketch to this post.
