NOICE!Why we think we should win:
We think that we should win because we were definitely thinking outside the cereal box when we designed and built our machine. Specifically, we think our machine is exceptional for the following reasons.
1) The machine is designed purposely to connect the last step to the first step, forming a very brilliant loop of chain reactions.
2) We have increased the complexity of the machine by adding multiple steps in between the pouring of the cereal and the placement of the cereal in the bowl.
3) Within our machine, we have incorporated two components that are typically used in the harvesting of grain and the manufacturing of cereal -- an auger and a conveyor belt.
4) The drill simultaneously powers both the conveyor belt and the auger.
5) We embraced the true spirit of Rube Goldberg by choosing to repurpose many discarded or second-hand items including slab doors, an old sink from a science lab and a fan motor. Most notably, we used discarded materials from the renovation of our math classroom. For example, parts of the frame of the kitchen set were constructed from discarded trim, the conveyor belt was created from a vinyl projector screen and plastic cable covers were used for marble runs.
Suggestion for next year's challenge:

The General Spills Brekkie Machine is Glendale High School's entry for the 2018 Rube Goldberg contest. This ingenious machine serves students a bowl of cereal allowing them to consume a healthy breakfast so that they can perform to the best of their ability. Special thanks to Ian and Cheryl Barton.
Our Step List
1. A hungry student slides a cereal bowl across the counter into the cereal-filling position which pulls the string attached to the bottom of the bowl. The string detaches a spoon under the counter releasing a ball.
2. The ball triggers the Newton's Cradle of golf balls. The final golf ball hits an egg.
3. The egg rolls down an inclined plane hitting a rat trap.
4. The triggering of the rat trap pulls a string closing scissors.
5. The cutting of the string drops a weight onto a seesaw.
6. The seesaw pivots causing a large marble to roll down an inclined plane.
7. The rolling marble hits a horizontally pivoting lever. The lever turns on a switch powering a fan motor.
8. The fan motor oscillates a blade cutting a string that is holding up a frying pan. The cutting of the string allows the frying pan to rotate.
9. The handle of the first frying pan hits the handle of the second frying pan causing it to rotate.
10. The string tied on the handle of the second frying pan pulls up on the blue board through a pulley. The upward movement of the blue board releases the spring of the mandoline.
11. The release of the spring propels half of a stale baguette located inside a spring-loaded mandoline. The stale baguette hits an onion.
12. The onion rolls and collides with the other half of the stale baguette on the edge of the kitchen sink.
13. The collision causes a marble to roll into the sink.
14. The marble travels down through the drain of the sink into a black tube and triggers the falling of the General Mills (TM) single-serving cereal box dominoes.
15. The Lucky Charms cereal box, magically but unfortunately not deliciously, hits the tall red lever at the side of the counter.
16. The red lever releases a marble. The marble runs down a ramp over the sink and knocks out a nail.
17. The release of the nail causes a magnetic wooden spoon to fall and pop the toast.
18. A skewer in the popped toast causes a marble to activate an elevator ramp.
19. The final marble at the top of the elevator ramp knocks over a butter knife which releases a tether ball on a paper towel holder.
20. The tether ball unwinds and hits a marble which rolls down a track behind the sink.
21. The marble collides with a salt shaker knocking the salt shaker off of a ledge.
22. A string attached to the bottom of the salt shaker pulls a platform hinged to the bottom of the Oatmeal Crisp Triple Berry box, causing it to tip. This box is filled with Nesquik, which we selected for its spherical shape.
23. As the Oatmeal Crisp Triple Berry box tips, the meat tenderizer embedded in the side makes contact with a copper wire closing the 12 volt DC circuit which activates the coil in the relay allowing the AC current to power the drill clockwise.
24. The drill turns the conveyor belt.
25. The conveyor belt delivers the irresistible Nesquik cereal to an auger.
26. The Nesquik cereal is carried along an auger (which "Stirs up some fun") and is directed through a fume hood into the cereal bowl.
