What we're studying:
The logic of physics

Our Team Leader's favorite quote:
If at first you don't succeed, do it the way Mrs. Van taught you.

Why we think we should win:
We believe we should win, not only because our machine is creative, but as a team we have persevered. As a team, many road blocks made completing this challenge a challenge.
In January, our team of four, began working on our design then construction in the school's basement . An inspection by the fire marshal required that our entire set up be moved to the opposite wall of the basement, This created almost a week of lost time while the team moved the entire operation. The next road block was the flu. Over a four week period there was not a single day when the entire team was in attendance due to the flu. Roadblock three - one of the team members transfers to another school.
As a team of three now, we refocused our efforts and really worked together during the last week of the contest to charge to the finish time!

Suggestion for next year's challenge:
Drop recycling into a recycle bin

Enjoy the operation of our unique machine while we point out point of interest in our home town of Frederick, Maryland

Our Step List

parenthesis represent the various sights in Frederick

1. release a bucke containing a ball bearingt, on zip line
2. the bucket slides down the inclined zip line tapping a Dixie cup containing a marble
3. the cup tips on it's side allowing the marble to roll out
4. the marble travels down a series of three inclined planes
5. the marble then drops into a tube (pvc pipe) (Baker Park)
6. at the end of the tube the marble drops onto a track, the rolling marble follows the track and drops down a small tube
7. at the end of this tube the marble hits the first domino, in a line of several, causing the remaining dominos to fall
8. the final domino taps the toy train car (with Angie riding) sending it down the track where it strikes the first domino
9. another line of domino falls through the Frederick Railroad tunnel
10. a doubled domino, attached to a line, drops off the table pulling a small tab from the top of the next component
11. the tab releases a ball baring which winds its way down a maze of tubes, both in and out of the box structure (Delaplaine Visual Arts Center)
12. the final ramp allows the ball baring to hit a sequence of ball bearings and strong, square magnets
13. force is transferred down the line - the last ball bearing is pushed with such force it works like a projectile(the open farm land of Frederick)
14. the projectile hits a CD case to a book to a tall piece of 2 x 4 lumber
15. the board has a line attached to it so as it falls it pulls a tab - the tab is above the wood about four feet
16. the tab releases a heavy ball bearing which proceeds down the marble run (The Great Frederick Fair)
17. at the bottom of the run is a large rubber ball that when hit by the ball bearing causes it to roll striking the first hanging container
18. this causes a sequence of three more containers to swing thus hitting a domino
19. several dominos fall landing on a lever that knocks another ball bearing down a piece of garden hose
20. the ball hits a flap of foam core which tips forward knocking another sequence of dominos
21. these dominos exchange the force through a curv ed line up where it finally hits a book (C. Burr Artz Library)
22 a chain reaction begins knocking down several books with the last book having a long line attached
23. the last book falls causing tension on the line - the opposite end of the line is several feet away on another table attached to a large book
24. the line is pulled taught causing the heavy book to fall on the on switch for a power strip
25 a fan now has power to blow causing a sail boat in water to be forced across the water (Carroll Creek Boat Race)
26. the sail boat hit the opposite side where it pushes yet another set of dominos
27 the last domino strikes a stick that has a long needle attached
28 the stick fall causing the needle to pop a balloon - the balloon has a hammer balanced atop it
29 the balloon pops allowing the hammer to fall
30.the hammer falls atop a nail the force is transfered to the nail head, thus hammering the nail (the continued growth of Frederick)
