Rube Goldberg

Last Friday we made marble tracks. Our class got the idea from, a pro at making marble runs, and his name is, Rube Goldberg. The people in my group was, Me, Rocky, Jabez, Ulil, and Vaifoa. My groups plan was for the marble to roll down the cardboard, and roll into a hole in the cardboard, and roll down another hill made of cardboard, and hit the domino's.When we were finally done, we told the teacher that it was done. But, it didn't work, so we made some modifications and it didn’t work again, so we made more modifications. We made many attempts, and our group never. but we ran out of time and didn't finish.
