Rube Goldberg Blog Post #2

Rube Goldberg machines are basically creations that you design to do a mini task for you, my task is that domino hit an empty water bottle into a garbage can. It didn’t take that long to make but the part that took long was the attempts it took many tries to make it work.

When I started building I needed to collect some materials. The materials I used on my machine were domino, a piece of cardboard, a garbage can, multiple golf balls, books, and finally an empty water bottle. After I collected my materials I got straight to work! As I got to work I was getting frustrated by the domino I kept hitting on accident! Although I made them fall a couple of times I got the hang of it.

Once I finished the build, it was a matter of testing. As I tried my first time I actually managed to get it on the first try. I freaked out of joy. I didn’t want to just end it there though. I tried multiple more times to see some fails and even if I could have it work again. I had three failures after my first try but then made it work again! It was incredible. I had to change one thing which was the domino’s hitting a ball that hits other domino’s but that wasn’t major. I changed my complete machine from the sketch I made.

After all that hard work that was put into it, it was time to take it down. I was proud of my work and think I did good on this project. Let me know what you guys think!

Today our group made a lot of improvements with our maglev train and track. We had to improve how the vehicle levitated. What we did to make our vehicle levitate higher we added one more strip magnet to both sides of the track to make two strip magnets stacked so we had a greater magnetic force so the train could levitate higher.

Our final track has two long strip magnets stacked on both sides of the track and our final train has two small strip magnets on two side so that when the train is on the track the magnets are directly under/on top of each other rappelling so it floats.

I learned that the maglev train is the fastest train in the world because of it’s levitation . I also learned that when you work in a group you have to listen to your friends because if you don’t they might be right and maybe you’ll agree with them. I also learned about the engineer design process it starts with the imagine the imagine is you brainstorming ideas for your train and track

The next is plan the plan is when you sketch the plan you imagined. The create is when you create the maglev train with magnets. After that is the improve on the improve you improve your project.

While I was improving I felt a bit frustrated because if it didn’t work it would be frustrating to make a new plan for the maglev but I also felt very excited because when it levitated it was so exciting to see it levitate above the track because if it levitated that means we made a good track and train. But in the end it was super fun.

Today me and my group got the vehicle to levitate above the track. On the vehicle we put 4 strip magnets around it, and on the track my group stacked 2 long strip magnets together on both sides of the track stacked 3 times.

Today my group failed on making the vehicle get steady while it was traveling on the track. We noticed that the long strip magnets on the sides were not exactly on the side. Then 1 person in my group noticed and we fixed it.

My groups goals for tomorrow is making our train levitate to the end of the track while having little rocks on it (Passengers) and if we fail we will try to revise it.

The Maglev train is a train powered by magnets and levitates. My groups idea for the train is to put a disc magnet in the middle of the train and put strip magnets around it, and the track had nine disc magnets in the middle and also strip magnets around the nine disc magnets.

Our car didn’t levitate it just stayed on the bottom of the track. Me and my group were trying to fix mistakes, but it was very hard. I think we will try a different way to make it levitate.

This project was hard because my group thought we had north poles on all magnets, so it would repel and levitate, but we had some south poles. My group thought finding the poles on the magnets was hard because there was no labels on the sides, so we had to stick magnets together to see if they would attract to each other or repel.
