Apply A BAND-AID®
Saturday, February 18, 2017 Setup Time:
7:00 AM Contest Start Time:
Live Division II - Ages 14 - 18 (High School)
What we're studying:
Simple machines, chain reactions, team work, designing and planning, and a bit of wood working in order to complete the projectOur Team Leader's favorite quote:
"Projects we have completed demonstrate what we know. Future projects decide what we will learn."Why we think we should win:
We have implemented strong engineering and woodworking techniques in order create reliably working steps for our machine. We have a wide variety of steps, not repeating particular simple machines over and over again and stereotypical steps such as "the domino step". Our machine is both aesthetically pleasing and functional that tells a compelling story line through the steps and the narration.Suggestion for next year's challenge:
Our suggestions for next years task would be, pour a glass of water, pop a balloon, and take a picture.Favorite Rube Goldberg video:
Hello and welcome to the Homestead High School Rube Goldberg Entry Page. We are super excited to compete in this years challenge! Our machine is modeled in the form of a band aid commercial. The art design, background and steps are made to look like a live studio set where a commercial is being filmed, with the judges and other viewers being the audience. Including planning, designing and building it took our team around five weeks to make our machine.
Our Step List
1. Our machine starts with a tire that we manually start spinning.
2. There is a toy car at the base of the tire that gets hit due to the wheel spinning.
3. This causes the car to go down a series of ramps in a zigzag pattern.
4. It hits a lever that releases a collection of ball in the top corner of the machine.
5. The balls fall down a funnel and spiral down a tube.
6. The force of the balls hit a lever.
7. This then triggers a string pulley system that releases a weight on the opposite side of the string.
8. The weight is lowered down and hits a see-saw.
9. The seesaw becomes off balance.
10. This triggers wheel pulley system that then transfers energy to the next group.
11. The energy transfers to a ping pong ball.
12. This causes the ping pong to roll down the ramp
13. This triggers a mouse trap
14. There is a string attached to the mouse trap. When the mouse trap is triggered, it pulls the string which pulls over the tower.
15. There is a ball on top of tower that falls off.
16. This pulls a string that is attached to the scissors.
17. The scissors are pulled shut which cuts a string with a ball attached
18. The ball falls into a cup
19. The cup activates a vertical chain (one side goes down the other side goes up)
20. The chain hits the ball and it rolls down a ramp
21. It hits a skateboard that rolls over to the next step.
22. There the marbles then fall down through a peg board.
23. This rolls down onto a ramp.
24. A mouse trap is triggered and pulls a bolt out of the rod.
25. A softball spins around and knocks over hammer.
26. The hammer falls onto a teeter totter.
27. The teeter totter lifts a bucket.
28. The bucket pours water into another bucket.
29. The bucket falls and pulls a string to trigger group four.
30. The energy transfer onto this group is by a Newton's Cradle.
31. The triggers a marble at the end the Newtons Cradle to roll down the ramp.
32. The ball the disconnects an electromagnet by rolling over it.
33. This causes a ball to fall and water to splash up and transfer water and therefore weight.
34. The off balanced side causes one side to fall slightly and hits a see-saw
35. The causes an electric car to zoom off
36. This then triggers a hatchet that hits a string
37. This triggers a ball to navigate downwards through a maze.
38. The ball hits an unstable upwards beam and it falls over.
39. The band aid falls with the rod and sticks to a fake hand.
