Open An Umbrella
Centennial High School
Saturday, February 27, 2016 Setup Time:
7:30 AM Contest Start Time:
Live Division II - Ages 14 - 18 (High School)
What we're studying:
We are studying gears, gravity, angles, momentum, electrical circuits, magnetism, timing, perseverance, and sheer luck.Our Team Leader's favorite quote:
"Who dares to teach, must never cease to learn." - John Cotton DanaWhy we think we should win:
We won nationals last year, and we are coming back with an even larger, more complex, and better looking machine than last year. We re-used and recycled a lot of parts from our last machine to save on money, and we also have double the brain power this year because our team doubled in size since last year.Suggestion for next year's challenge:
Turn a single light on AND off.Favorite Rube Goldberg video:
Mary Poppins inspired machine that has you floating away with your umbrella by the end.
