Objective – To pour water into a cup for our buddy because poor buddy is just to short to reach the water.

Steps

1. The Rube Goldberg starts when I flip the switch which then turns on the light and the light is necessary so that the M Bot can go.
2. When the M Bot senses the light, it goes according to how I programmed it too much earlier.
3. The M Bot hits the lacrosse ball which then falls into the cup.
4. The cup is attached to a ribbon which pulls away a block in front of a wound-up car toy.
5. The car toy then moves and hits a tennis ball.
6. The tennis ball falls into a second cup.
7. The second cup is attached to a water bottle by a string and pull down
8. The water bottle is pulled down which begins to pour water into the cup below for our buddy
