The process of starting the Rube Goldberg project was fun very fun. Some resources I used were dominos, hot wheel tracks, and other useful objects like cups and paper toilet rolls. Another resource I used was the videos attached to the google document, I count them as resources because those videos gave me ideas. Something frustrating is that on some of the tries it was very close to working out, but then it would malfunction and that got me frustrated. One thing that was challenging was getting the sketch to look like the actual machine. Another thing that was very tricky was when the machine would break down in the middle of an attempt. One revision I had to make was because my car didn’t have enough power to go down the track and activate the spring machine to launch hot wheels so instead I used a hot wheel power pusher, that revision helped me a lot. I have three simple machines my first one is a lever my second one is a wheel n axle and my third one is an inclined plane. One moment I had was when I realized that my pulley wasn’t going to work for this machine.
