The process for designing the machine and testing it was really fun! I loved coming up with ideas. Something that was challenging was finding the materials, but I got a lot of inspiration from YouTube videos, and from my sister.

So far my testing was good, something that has been frustrating was some of the ideas that I was coming up with, that I thought were really good, were not working. I had a few challenges here are some of them:When I was building I had a three foot drop in my build, but that was not working so, I made an inclined plane for the ball to roll through. Another challenge I came across was I had a golf ball going down an inclined plane and it kept on flying out of the ramp so I changed it to a different ball and then it worked.

My “Aha moment” was when I was building, my first step originally was a marble would go down a structure and hit a toy car, but the problem was that the marble was not heavy enough to move the car. This was a big problem because without this step the whole project would not function. I tried to change the car to a ball but the marble still would not move it. So I decided to remove the whole marble run step completely, and start of with the car going down the ramp. Then I added a fan at the end of the Rube Goldberg.

Overall my Rube Goldberg journey has been great.
