Rube Goldberg 4
Yesterday Leo and I met to finish our Rube Goldberg machine. When we assembled it, the hardest thing was the marble hitting the tablet because we had to make a cardboard tube turn so that the marble would hit the tablet at the right angle. Another thing that was hard was attaching the string for the shoe to the ceiling because Leo and I could barely reach it, so it became very hard to tape the string. When we finally did it, we added a new step that included a water bucket where the weight of the bucket that is full of water would pull on the pulley, instead of using a person. The whole machine was assembled in a hour, so we still had a lot of time to finish.
