Our team consists of five 7th grade girls. Our team name is Team TEAMS. T for Taylor, E for Emily, A for Amy, M for Mirian, and S for Savannah. We go to Esperanza Middle School, and our engineering teachers are Ms. Meny and Ms. DiCola. We've been working on a Rube Goldberg Machine for about 3 months, only meeting up 3 times. Somehow, we managed to get an amazing machine. We're very proud of our work, and are excited to show it off in the competition. WOOH! We never thought we'd make it this far!

[Note: We combined our explanation and actual machine running into one video.]
