Team # 333: Theory Of Raditivity TEAM PAGE

North Tama School District
Traer, IA, United States

Online Contest:
Open An Umbrella
Online Division II - Ages 14 - 18 (High School)
Team Leader: Logan Mork
Team Members: 6
Invitations: 0



What we're studying:
We are currently studying work and energy.

Our Team Leader's favorite quote:
"Imagination is more important than knowledge." Albert Einstein

Why we think we should win:
We are six students who have spent a semester learning about energy, transfer of energy, force,and many different topics in our physics class. We should win because we have taken all of this newly learned information, and applied it to the Rube Goldberg challenge of opening an umbrella. We have spent a lot of time in the back of our classroom setting it up, having trial runs, and brainstorming more steps. The time and work we have spent in perfecting our machine and learning how to make it better is why we should win this year’s competition.

Suggestion for next year's challenge:
Turning on a flashlight. We also thought that it would be fun to have chances for bonus points if the machine met other secondary objectives.

Favorite Rube Goldberg video:

Our machine opens an umbrella using household objects, Hot Wheels, and massive amounts of tape. We use large steps to craft a fluid aesthetic and multiple transfers of energy to keep the viewer engaged. We use various levels throughout the machine to add movement, with the overall goal of creating a whimsical, fun, and zany machine.

Our Step List

1. Team member pushes Stitch (action figure) off of book
2. String attached to Stitch pull up tape
3. When the tape is high enough, it releases the pool ball
4. The pool ball goes down ramps and hits wood block
5. The block moves to release car
6. Car hits down cardboard
7. Cardboard falling releases swinging pool ball
8. Swinging pool ball hits golf ball
9. Gold ball goes down track into cup, pulling a string
10. That string being pulled releases balls in plinko board
11. Balls fall down plinko board, pulls string
12. String releases pin
13. Pin releases pool ball in ramp
14. Pool ball goes down ramp, hitting another pool ball
15. Both balls continue down ramp, hitting a lever
16. Lever moves, hitting wood block dominos
17. Wood block dominos fall, allowing car to be released on the track
18. Car goes down track, hits golf ball
19. Golf ball falls, hits orange plastic plate, knocking it over
20. Plastic plate hits whiffle ball(on string), sending it over ledge
21. While it falls, it pulls the string, releasing the car
22. Car goes down track, into bucket, activating pulley
23. Bucket goes down, pulls out pin
24. With the pin released, pool ball is released down a ramp
25. Pool ball is stopped by wire, transferring the energy to the wire
26. Wire transfers energy to tennis ball on string, tennis ball falls off platform
27. Tennis ball falling off platform pulls down cardboard holding back Spider-Man
28. Cardboard being pulled down releases Spider-Man, Spider-Man zip lines down
29. Spider-Man pulls string attached to wooden rod at end of zip line, pulling rod out of position
30. Rod being pulled out releases meter stick, meter stick falls
31. Meter stick hits toy utility vehicle
32. Toy utility vehicle goes down ramp, hits tennis ball(with Newton cradle holder attached)
33. Tennis ball falls, bringing Newton cradle holder with it, releasing Newton’s cradle
34. Newtons cradle hits metal piece onto another metal piece, activating drill
35. Drill runs, opening umbrella.
