Rube Goldberg #3

Today I started to build my Rube Goldberg. So far we didn’t make too many changes to our idea, but we figured out some little things that needed to be changed. Some of our materials we are planning on using are dominoes, a toy car, books, ping pong balls, golf balls, toilet paper rolls, popsicle sticks, a roll of duct tape, and car tracks. It’s really exciting to see our idea come to life and I’m very proud of what we have done so far. I thought the project would be much easier but, it took a lot more work than I thought. Some difficult parts were putting together the ramp we made with toilet paper rolls. It was difficult because we had to make it smooth enough so the ball doesn’t get stopped. We also had to make it sturdy enough because we will be rolling a golf ball down the ramp and golf balls are heavier then most small balls. Rube Goldberg is all about creating machines to do a simple task, and our simple task is feeding my sisters hedgehog. I’m so excited to see our final product and I can’t wait!
