This week, I will start building, which means I will start gathering materials. For my Rube Goldberg machine I’m going to be using materials such as, dominos, bouncy balls, wood, cardboard, books, lensless glasses, tennis balls, etc. Some of these materials I made, some of them were old toys, and some of them I use for activities. While building, there is a good chance that I will not follow my plan exactly, so I might add or eliminate steps depending on how the building process goes. While looking for materials for your Rube Goldberg, I suggest checking your garage, basement etc. You never know what you can find! I also suggest looking through some of your old toys. The next step to my Rube Goldberg is building!! Yay!!!
