For our meeting, we tested our Rube Goldberg a bit more. We changed it a bit so the chance of failure is a lot lower. We changed a ramp so the ball would have a higher chance of hitting the dominoes. The ball used to miss the dominoes a lot. That’s why we had 37 fails from our meeting on Friday. (2nd blog post)We had our first success after 42 fails!

After our success, we decided to add some more steps to our Rube Goldberg because our Rube Goldberg was around 50% ramps and dominoes. We added a marble run contraption, which was really challenging. (A marble run contraption is a contraptions made of all kinds of tubes, and a marble goes through whatever contraption you built.)We had to secure the contraption with lots of tape. Once we did that, we discussed how else we can improve our Rube Goldberg with some really cool ideas, like a Nerf gun in the beginning. and went downstairs because our meeting had to end soon. After the meeting ended, my mom and I discussed some more ideas for the Rube Goldberg. My mom got a really cool idea that had something to do with acid base reactions. Now I’m super hyped for our next meeting!!
