What we're studying:
Currently, we are studying B-fields in preparation for the AP Physics C tests this upcoming May. Our Team Leader's favorite quote:
"I have not failed. I've just found 10,000 ways that don't work." -Thomas Edison Why we think we should win:
Our machine is not one created through exorbitant expensive features, but through experimentation and creativity. Based off many sleepless nights and the generous donation of Mrs. Park's dining room, we conceived a machine akin to the original Rube Goldberg's we were inspired by. By raiding our recycling bins and making many adventures to the home depot, we have dedicated ourselves to our machine and this challenge as a whole.
As elementary school-ers, we built these machines using things we found in our respective homes. Emulating videos we watched on YouTube, we hope to inspire kids to search their own cluttered basements and start their own adventures. Suggestion for next year's challenge:
make a volcano explode
With being faced with the task to "pour a bowl of cereal," we interpreted this as not only adding the cereal and mil but also serving the bowl to the consumer. With the morning being a groggy and oftentimes slow process, we felt it was appropriate to make the viewer do as little work as possible in being able to enjoy a freshly prepared bowl of cereal. Our theme is intentionally low-tech in classic Rube Goldberg style in order to preserve his tradition of using household and simple transfer tricks.
Our Step List
1. Trix car falls and knocks domino.
2. String pulls releasing a ping-pong ball.
3. Ping-pong ball ricochets off inclined wooden block into a cup.
4. Cup falls and knocks into a domino.
5. Domino knocks ping -pong ball down a track.
6. Ball strikes tongue compressor and transfers energy into another domino.
7. Domino knocks down a truck.
8. Truck releases magnets down a track.
9. Magnet acts upon other magnet, causing Jenga tower to fall
10. Falling tower releases ping pong ball down track
11. Ball hits a singular domino which pulls a notecard releasing a marble.
12. Marble falls between sheet of plexiglas, which causes ball to continuously spin.
13. Marble collides with Jenga block, releasing string with wooden block attached.
14. Wooden block releases a golf ball.
15. Golf ball collides with a battery.
16. Battery pulls a lever which allows car to continue down the track
17. Cereal car collides into a domino, allowing a marble to fall.
18. Marble pushes into a cylindrical magnet, pushing magnet into the air.
19. Magnet attracts to loose nail and pulls it, which releases a bouncy ball.
20. Due to the unbalanced weight within the tube, a golf ball falls from the other side and onto a track.
21. Golf ball rolls and knocks over a wooden block.
22. Wooden block releases a tape measure.
23. Tape measure collides into a Jenga tower, pulling a string.
24. Ball falls from the pulled string, thus pulling more strings (occurs 3 times).
25. Final string pulls a slit which releases a yellow sponge ball.
26. Sponge ball collides into Jenga blocks, which allows lever to move a ball upwards.
27. Ball collides into dominoes, which trigger a string.
28. String allows car to fall down track.
29. Car collides with hinged wooden panel.
30. Wooden panel allows the milk-filled canteen to drip milk into a funnel and down a tube.
31. Wooden panel also strikes a block which releases a marble into a maze (happens while milk gets to cereal).
32. Marble moves through maze and hits popsicle stick (happens while milk gets to cereal).
33. Popsicle stick strikes tennis ball (happens while milk gets to cereal).
32. Tennis ball strikes "Your cereal is ready" sign (happens as milk gets to cereal).
33. Milk pours onto cereal.
