For our 4th meeting, Bryan and I are doing the hardest part. We are making a maze that is connected by little pieces. After we are done, the marble will roll down and hit a button on a power switch and it will turn a lamp on. So, we start building everything and after we were done, we realize it wasn’t so hard. We had to make the hole straight on top of the power socket so the marble could fall on the button. It was kind of hard to make the marble fall straight on the button so we made a tape tunnel and when we finished we tested it out. It worked, but then after testing it again the marble stuck to the tape and Bryan was taking everything apart. That second the doorbell rang and Bryan had to leave.
