Our Team Leader's favorite quote:
We are all living in the gutters, but some of us are looking at the stars. --Oscar Wilde

Why we think we should win:
We rock...We spend a lot of time working together on the machine, and have many original ideas. Our machine is very theme-oriented, and shows the international energy in our school. Everyone loves this machine. Our materials are mostly hand-made from everyday objects. We used effectively our knowledge from physics class.

Suggestion for next year's challenge:
Pulling a piece of tissue from the tissue box.


Favorite Rube Goldberg video:

Our international theme is designed around 5 continents. We are first in Asia where we travel down Mt. Fuji and the Great Wall of China. It enters the Pyramids of Egypt (Aftrica) where it ends with a giraffe going down a cart and entering Australia. Australia creates a way into Europe which ends with North America pulling a boot to open up the umbrella.

22. balls hits a domino at the bottom of the ramp
23. The last domino has aluminum foil on and falls down and completes a circuit
24. Circuit will engage an electromagnet
25. Electromagnet will pull a sting that pulls the Leaning Tower of Pisa down.
26. The Leaning Tower of Pisa will fall onto a string, rotating the ferris wheel.
27. The Ferris Wheel will move a tennis ball forward.
