The process of my Rube Goldberg machine was very hard. The hardest part was actually building the machine. It took at least 10 tries just to get one step right.

I had lots of challenges and troubles. One problem was that I could not find the right sizes of materials I needed. It was very hard to find things that are the right size and shape. Another problem was that my machine started with dominoes so if one fell over then the entire machine would start and I wouldn’t be able to get it on video.

Some of the materials I used were marbles, cars, blocks, dominoes, and car tracks.

After I tried out my sketch it did not work. My final machine looked very different than I had planned. Something that was originally in my sketch but I did not use in my machine was a water balloon. Something in my sketch that I did use in my machine was dominoes.

Overall the hardest part was building the machine. My final machine took 81 tries. So far I had lots of fun with my Rube Goldberg project.

This is my sketch:
