Our Step List
We decided to use a sports theme for our Rube Goldberg because we all play several sports and love competition and being a part of the team. We used several pieces of sports equipment like cones, pucks, golf pegs, baseball bats etc. to complete our machine. For our first step, a mini-bat swings down and hits a golf ball. The golf ball rolls down wooden plank, falls through an orange cone to a row of dominoes. On step 2, the ball hits the first domino in the line and knocks down a row of dominos. For step 3, the last domino falls to knock a golf ball down a pegboard, through golf tees that are sticking up to make a track. The golfball hits another line of dominoes at the bottom of the pegboard for step 4. For step 5, at the end of the domino line, the last domino falls off of the table and pulls another domino down, which is attached by a down and is blocking a car from going down a track. The matchbox car is released and goes down the track, under a wooden tunnel and hits a hockey puck off of the table for step 6. In step 7, the hockey puck falls off the table and turns on a small fan. In step 8, the fan blows a light weight ball across the table on a track. The ball hits a short row of dominoes for step 9. In step 10, the last domino falls off the high table and releases a domino that is keeping a matchbox car from going down a track. A matchbox car goes down a track and hits another series of dominoes for step 11. For step 12, the last domino falls and launches another car down a track hill. In our final step, the car hits a hockey puck off of the shelf and the hockey puck falls and zips a zipper on a sweatshirt that is hanging upside down from the door of a closet for our 13th and final step.
