What we're studying:
This device was constructed during our "A" block enrichment period. We studied bridge design; as well as potential and kinetic energy. We also learned to used basic hand tool techniques to construct our device.

Our Team Leader's favorite quote:
"...and that's why you always show your work!"

Why we think we should win:
Because it took us 253 attempts to get it to work correctly the first time. We constructed most components from scratch and have worked over 6 months to get it right. We tried to make it interesting and challenged ourselves to see how complex we could make it.

Suggestion for next year's challenge:
Pour a glass of milk and dunk a cookie into it.

Favorite Rube Goldberg video:

This machine uses a lot of marbles, dominos and release pins. Thanks to one team member's dad we had a lot of scrap pine. Mr. Whitworth brought in some basic handtools and a hot glue gun we used to construct most of our devices. Each team member was responsible for building his/her own component and then they were linked together. Everyone then helped with the fine tuning and any modifications needed.
