What we're studying:
We are 10th and 11th graders who know little about physics (except basic 8th grade stuff) but we enjoy what we do. Why we think we should win:
Our team has worked hard with what we accomplished and are proud of we had done. We have dedicated all of our lunches and after school hours to make this project. We hope that this machine can inspire creativity in the minds of all who view it. Suggestion for next year's challenge:
1. Pull a cork out of a bottle.
Favorite Rube Goldberg video:
Our Machine is an industrial antarctic wonderland made of wooden blocks, bamboo skewers, toy cars, a rotating motor, and a DIY pulley. Our machine is not extremely extravagant but we pulled through to make what you will soon see.
