Rube Goldberg machine

LI: to make a Rube Goldberg Machine.

We made a Rube Goldberg Machine that includes all of the six simple machines. We had to choose one of three things that the Rube Goldberg machine has to accomplish. The things that we had to choose from were rolling dice out of a cup, putting a ball into a cup and to turn a chrome book on. The thing that we chose was to roll the dice out a cup. 

Our first plan was having an incline plain and a marble hit dominoes, but that plan didn't work because the dominoes kept falling back so we made another plan. Our final plan was first hitting the books with a bat hitting a backwards wedge down an incline plane to hit a person and that person cut's the string that is attached to a felt tip pen. The felt tip pen dropped and hit another person. He will then push another person and that other person will lift a chair from the back to make a car roll down an incline plane to hit the cup and roll the dice inside.

Making the machine was a challenge because we had to figure out what we would make our simple machine out of. I would have changed the string part because it did not cut and I would have also changed the toy car to something else because it got stuck in the tunnel.
