Apply A BAND-AID®
Online Division I - Ages 11 - 14 (Middle School)
What we're studying:
We are studying physics and its applications to the real world. Our Team Leader's favorite quote:
"The only difference between science and screwing around is writing it down." -Adam SavageWhy we think we should win:
We think we should win, because we spent a lot of time and effort on our machine, and we feel that it is really cool. (We also want the money :D)Suggestion for next year's challenge:
For next year's challenge, we recommend that the machine should count for more, and the theme should count for less. We think that the competition is evaluating the physics of the machine, not its theme.Favorite Rube Goldberg video:
Our machine was built using fundamental principles of physics, including Newton's Laws, and Conservation of Momentum. We designed it with the outdoors in mind, so we added grass, a river, a badger, and coal counterweights to our machine. Sports are also played outdoors, so we included sports items like a baseball, a racquetball, a field goal, and a golf ball.
Our Step List
1. We have 2 metal cylinders balanced. We tip the balance, causing them to roll down.
2. They hit a racquetball, which rolls down and hits a golf ball, which rolls down and hits a baseball.
3. The baseball rolls down, knocking over a weight that is attached to a string. The other end of the string is attached to a pair of scissors.
4. When the weight is knocked over, the scissors snaps shut, cutting a string. This string runs up through a pulley, and has a weight attached on the other end.
5. When the string is cut, the weight slides down, knocking into a piece of slide-able cardboard.
6. The cardboard slides forwards, knocking a bottle of water over.
7. The bottle pours the water out through the badger's mouth, disrupting a scale.
8. When one side of the scale moves down, it causes a weight attached to it to swing forward.
9. It then hits a baseball, which begins to roll.
10. The baseball then hits a weight, which is on top of a string connected to a ruler.
11. The string holds the ruler back, and when the baseball hits the weight, the ruler snaps forward.
12. The ruler knocks into a bouncy ball, which rolls forward until it hits a block.
13. This block then falls onto an open band-aid.
