What we're studying:
Potential Chaos's team members consists of students from California State University, Long Beach studying various Engineering disciplines. We have Aerospace, Electrical, Mechanical, Computer Science and Chemical Engineering majors on board.

Why we think we should win:
We believe Potential Chaos should win because between school and all of our busy schedules, we were able to successfully make our Rube Goldberg machine within three weeks! We used to fiddle around with objects and build random contraptions as children, so as students pursuing a major in Engineering, it's been fun to be able to do that. We have also attempted to incorporate all engineering disciplines onto our machine. For example, we have 3D printed parts, coded a program to turn on a fan, and built a small circuit as part of our step designs.

Suggestion for next year's challenge:
A few suggestions that our team came up with for next year's challenge would be to turn on a fan, staple paper, tie a knot or play a song.

Favorite Rube Goldberg video:

Join Potential Chaos for a day at the park! Our Rube Goldberg machine's story starts off with a softball game at the park. The batter then hits a home run into a tree causing a chain reaction of unfortunate events; turning our machine to describe one of the "worst day at the park." However, all of the chaos that unravels throughout our machine is easily fixed with a band-aid -- whew!

The machine was built by the members of Society of Women Engineers at CSULB. We hope you enjoyed our project and thank you for watching!

Our Step List

(Story: The day starts off with a baseball game)
1. Spring is pulled back causing a elastic potential to release and swings the stick which hits the ball
(Story: The batter hits the ball)
2. The ball takes off and hits the book
3. The book is knocked over and hits the tree
(Story: The baseball flies into the tree and startles a bird)
4. The vibration of the tree results in the origami crane to be released from a height
(Story: The startled bird flies out of the tree)
5. The crane falls along a string, losing gravitational potential and gaining kinetic energy, and hits the doll
(Story: There is a young girl sitting on the bench and falls off the bench due to the bird flying too close)
6. The doll is knocked off the chair and hits the lawn rake, which is positioned upwards due to a weight (recycling bin) on the other side
7. The lawn rake being pushed down on one end then causes the recycling bin to tip over and a golf ball rolls out of the bin
(Story: Now, the chaotic chain of unfortunate events begin!)
8. The golf ball rolls down to the second tier of the machine and hits the swiveling platform
(Story: Someone's golf ball is lost in the lake)
9. The swiveling platform knocks off a piece of balsa wood covering a photoresists
10. The photoresistor, powered by a battery, turns on a fan which then propels a toy sailboat forward
11. The toy sailboat has a magnet on its hull which attracts to the magnet on the dock
(Story: Toy sailboat is coming in TOO quickly towards a pier)
12. Sailboat tips a car down a ramp
(Story: People in the car is afraid, and takes off in case there is an impact from the sailboat on the pier)
13. The car knocks a granola bar into a magnetic, which rolls into a goal
(Story: A soccer game is in session and the car drives right onto the soccer field)
14. The magnetic stopped at a goal attracts the other magnet, which is tied to a string, yanking on the string
15. The string releases a platform with marbles at a height
16. The marbles drop onto a seesaw and tilt the other end of the seesaw
17. The other end of the seesaw raises and unlatches a rubber band with a cap attached that is held tightly
18. The cap hits the basketball hoop pole
(Story: A basketball game is halt due to the commotion at the soccer field)
19. The basketball hoop pole vibrates and a ball held at equilibrium falls off the hoop
20. The ball knocks into a domino, which then knocks the golfball down a ramp
21. The golf ball knocks a roll of tape off a ledge
(Story: People playing golf are startled by the commotion in the soccer field)
22. The roll of tape tugs on the string and pulls up a pin that was holding a spring in place
23. Spring releases and two arms rotate around
24. The arm knock a golf ball down a ramp
25. The ball falls into the bottle
(Story: A ball hits a water hydrant which cracks the hydrant)
26. Golfball displaces water and the water level rises out a hole on a side of the bottle
(Story: Water is flowing everywhere!)
27. As the water is spewed into the cup, the seesaw lowers and lifts the opposite end which is connected to a platform
28. A car is released from rest due to the inclination of the platform and hits a weight off the ledge
(Story: a car rushes away from the water and a squirrel rushes away in time)
29. The weight falls causing the four-bar linkage mechanical system to unlatch
30. The mechanical system is activated and applies the band-aid
(Story: A band-aid solves most of the chaos... except for the cracked water hydrant)
