In our fourth meeting me and Alex both worked hard. We took so many videos but we didn’t have a success. We made so many small changes to our Rube Goldberg machine. One of our main problems was our wooden car that we built. The car would always go of the side of our ramp. The car broke 3 times! We used the hot glue gun constantly. We almost forgot to switch the glue gun off. After so many tries we finally finished our meeting with no success. We were disappointed on how we did but, we were determine to get a success on our Rube Goldberg machine.
