Today we started building our Rube Goldberg there was not too many changes to our idea we are planning to stick to our sketch. Our Rube Goldberg is going great, I am very excited to see what will happen when we have our final Rube Goldberg is done. It is a lot harder to build the Rube Goldberg then I thought it would be. There has been some ups and downs with our Rube Goldberg one down was that the dominos were very hard to do, because they kept on falling. One up was that our ramp that we made out of toilet paper rolls is working really well! I am really proud of our Rube Goldberg!
