What we're studying:
We have a mixed group of 9th, 10th, 11th, and 12th graders who are currently studying AP Physics, AP Chemistry, AP Biology, AP Environmental Science, AP Calculus, and more!Our Team Leader's favorite quote:
That's Money Honey!! (Proclaimed when Honey Nut Cheerios land in bowl!)Why we think we should win:
Our machine diverges into two paths: the cereal path, which pours the cereal and drops the spoon, and the milk path, which pours the milk a moment later. What cereal breakfast would be complete without the milk?Suggestion for next year's challenge:
Take a selfie.
Our Rube Goldberg Machine is innovative as it is a representation of classical Rube Goldberg Machine tropes with a modern twist involving a chemical reaction. The ongoing theme of the machine is the diverging of paths each dedicated to a specific part of the cereal making process. The bottom pathway delivers the cereal while simultaneously the top pathway unleashes the milk. In rapid succession, the cereal, milk and spoon all converge into the bowl. The main focal point of the machine is a classical chemical reaction of baking soda and vinegar. This step alone combines our group’s knowledge of chemistry and physics as a climactic finale leading to delicious product of breakfast.
Our Step List
Step 1: Person knocks alarm clock into a pot (the falling of the alarm clock also releases a golf ball onto a track *see step 19*)
Step 2: The weight of the alarm clock lifts up one side of the lever, while the other side hits another lever
Step 3: Second lever lifts up, thereby allowing a small-sized marble to roll down said lever and hit a medium-sized marble
Step 4: The medium-sized marble rolls down a ramp and hits a pole
Step 5: The top of the pole hits another medium-sized marble
Step 6: The medium-sized marble rolls down a ramp and hits a small metal ball
Step 7: The small metal ball then proceeds to roll down a ramp, colliding with a hammer
Step 8: The force of the hammer strikes a pool ball
Step 9: The pool ball collides with a pole, releasing a toy car
Step 10: The toy car rolls down ramp and lands on a lever
Step 11: The lever releases a small wooden ball onto ramp
Step 12: The small wooden ball smashes into an upright wooden block
Step 13: The wooden block falls onto a lever, lifting up the other side which releases a rubber rainbow ball
Step 14: Rubber rainbow ball collides with a pole
Step 15: The pole hits a croquet ball
Step 16: Croquet ball falls into a pot
Step 17: Weight of pot lifts up one side of a lever, allowing for the release of the cereal
Step 18: A string is attached to the cricket ball and a stick, the falling of the cricket ball thus initiates the fall of a spoon into a bowl by releasing the stick holding the spoon in place.
Step 19: The falling of the alarm clock releases the tension of a string allowing the liberation of a golf ball
Step 20: The golf ball travels through a series of ramps until it collides with a long, wooden stick
Step 21: As the long, wooden stick begins to fall, it crashes into another golf ball
Step 22: The golf ball falls into a bucket
Step 23: The weight of the golf ball initiates a pulley, allowing the release of baking soda
Step 24: The baking soda thus falls into a beaker awaiting below
Step 25: The beaker contains vinegar, so the mixture of the baking soda and vinegar, instigates a chemical reaction
Step 26: The product of the reaction starts to overflow out of the beaker, descending down a makeshift track, eventually landing into a small plastic bucket
Step 27: The weight of the product in the bucket loosens the tension of a string, releasing a small, but dense metal ball
Step 28: The metal ball runs down a track, colliding with large circular weight
Step 29: The weight falls off the table and as it swings, the weight of the weight releases the cap off the milk
Step 30: The milk finally falls into a tunnel and down a tube into the bowl of cereal
