What we're studying:
How well we can build a machine in someone's basement.

Our Team Leader's favorite quote:
'"You are a hard man, Odysseus. Your force is greater, your limbs never wear out. You must be made all of iron, when you will not let your companions, worn with hard work and wanting sleep, set foot on this land, where if we did, on the seagirt island we could once more make ready a greedy dinner; but you force us to blunder along just as we are through the running night, driven from the island over the misty face of the water."'

Why we think we should win:
We have the man power. We have the materials. We have the ingenuity. BUT! Do we have the grit? Yes we do.

Suggestion for next year's challenge:
Shoot a basket.

Favorite Rube Goldberg video:

Our machine is a blast to the past with the ancient civilization theme. Viewers can witness a journey that starts in China, speeds into Egypt, flies into Rome, blasts to the Mayan Empire, and then comes full circle back to China before dispensing cereal from an 11th century pagoda.

Our Step List

2017-2018 Glenbard South Rube Goldberg Steps List
1. A ball is dropped into the bowl and rolls down the ramp
2. The ball hits a lever that pushes a ball down the next ramp
3. Said ball hits the next lever, which pushes a stick
4. The stick pushes a ball off of the ramp
5. The ball falls into the see-saw, causing the container to fall
6. The container pulls down on the string
7. The string is pulled down, releasing a ball which rolls down the ramp
8. The ball rolls down the ramp and into the funnel, falling onto one side of a seesaw
9. This side of the seesaw falls, causing the incline of the ramp the train sits on to increase
10. The train rolls down the ramp and pulls on the top piece of the scissors
11. The scissors cut a string with a ball attached and the ball falls onto the ramp
12. The ball rolls from the ramp into a bucket attached to the magnetic pivot wheel
13. The wheel lifts a piece of plastic
14. This piece of plastic hits a gear and causes the gear to turn counterclockwise
15. The gear pushes a marble down a ramp
16. The marble removes a support from a metal beam, causing the beam to swing in a downward motion
17. The beam hits a string
18. The string falls and pulls out a piece of plastic which was previously stopping a ball from rolling down the ramp
19. The ball rolls down an incline and smacks a weight down through some tension it was previously sitting on
20. The dropping weight yanks a magnet that was stopping a ball bearing from rolling down a ramp
21. This ball is directed nearly downwards and flies into a small carriage sitting on the ledge of the upper layer of our machine
22. The small carriage and ball bearing pull out a pin on the base level thanks to a series of pulleys
23. This pin releases a heavy nut and causes it to fall
24. This nut lifts up one side of a track due to a pulley which causes a metallic ball to roll down the incline
25. The ball completes a circuit of a bicycle wheel rotating
26. The wheel knocks a small ball off a ledge
27. The weight of the small ball and some washers causes a remote control to operate
28. The remote control tells a remote car to drive forwards
29. The car runs off a ramp, and the weight of this action warrants a magnet being ripped away that was holding a metal ball on a track
30. This ball rolls down a spiraling ramp until it hits another ball, which continues down the ramp
31. The second ball travels out of the spiral before causing a magnet to be pulled along with it in motion
32. A stick is yanked due to the movement of the magnet
33. This lets a golf ball roll down an incline track
34. The golf ball lands on one side of a teeter totter.
35. The other side of the teeter totter sends a large spool into rotation due to an arm sticking out from the spool
36. The spool arm wacks into a slightly tight string
37. This motion pulls a magnet that was attached to a ball away from a track
38. The ball rolls down a ramp before it smacks into the paddle of a model boat
39. The paddles on both sides of the boat are connected, which causes a ball in the other side of a boat to be subsequently knocked down a ramp
40. This ball falls into a funnel which leads a ball to bump into a long thin tube
41. This tube knocks another ball down an incline at an elevated height
42. This ball flies into a pedestal, thus knocking it down
43. The sudden loss of the pedestal causes a weight to fall down
44. This dropping weight leads to a toothpick being pulled from an inclined plane
45. Due to the loss of the toothpick, a ball is now free to roll down a series of ramps
46. This ball finally hits a very large and heavy ball which sets it in motion.
47. This heavy ball drops into a bucket attached to a pulley
48. The weight of the ball causes the bucket to rip away the other side of the pulley which consisted of a magnet attached to a grounded metallic ball
49. The sudden movement of the string in the system causes a cardboard wall to lift up
50. This releases a ball that rolls down an incline
51. This ball eventually knocks into a heavier ball
52. This ball rolls down a circular ramp before eventually knocking down on a lever
53. This causes a metal ring to be released from under a hook on the other side of the lever
54. This release of tension causes a piece of cardboard to unfold from a v shape to a straight shape
55. This change of shape lets gravity set in and pour our cereal down a series of ramps and into a bowl
