When Ian and I got to Jonny’s house Jonny told us about his Idea. We were going to hit a water bottle into a cooler. Ian and I agreed. We started building, but we had one problem. How are we going to get an object to the top of the cooler. That’s where I came in. I said we should put dominoes on a box onto a higher box etc. Then when we reached the top the domino would hit the water bottle into the cooler.
I think that Jonny, Ian, and I should try to shorten our Rube Goldberg because we aren’t meeting every day and our Rube Goldberg is pretty long. I think we should also shorten it because since we don’t meet that much we won’t have that much time to do our final take.
The last time our Rube Goldberg group met we wanted to make sure our course worked. We did it over and over until we were satisfied. We made adjustments to the car and the dominoes after the marble track. Now we know that our Rube Goldberg works. We also added a few ideas. For example, we put a domino on it’s side so the marble will bounce off it and hit dominoes. Also, we changed the car so that it will hit the marble every time. This idea took a lot of tape, but it worked.
