We did our Rube Goldberg machines. Our challenge was the putter challenge. We had to push cars into a marble. The marble rolls down on a Incline Plain. Then the marbles hit the Dominoes and the last domino has a pin. The pin will pop the water balloon the one of us hits the golf ball with a putter into a cup. We used Marbles, Putter, Dominoes, Golf ball, Pins, Balloon. String, ruler and water. The simple machines we used was the Incline plain, Wedge, Pulley, Lever. The dominoes were challenging to go through because every time the marble goes down the ruler the marble only hits some of the dominoes but not all of it. I would change the dominoes with a card board track instead. So the marble will roll smoothly on the card board into the last domino with the pins on it.
