Rube Goldberg Competition
Objective
2018
Open a physics book to page 114.
PurposeTo demonstrate scientific skills, creativity, teamwork, and have a funtastic time.
ParticipantsTeams of three to six.
Materials

Supplied by the Team. The Rube Goldberg Machine will be built and tested at school.

RulesThe machine must occupy a maximum space of  2.00 m x 4.00 m, and points will be awarded for making full use of the specified area.
Two attempts will be allowed to attain the objective. Both runs will be marked.
Judging
1 point for each event or action
5 points for succesfully achieving the Objective.
5 points for aesthetic appeal
5 points for creativity.
1 point for each different principle of physics employed
 -5 points for each assistance beyond the first.
 Machines will be judged on their use of recycled materials.

10 Points will be deducted from the final team score if a visible footprint of their presence is still detectable 20 minutes after the end of the competetion. Clean up your mess!

If a part of the machine fails, the team can restart it once without penalty.
If subsequent restarts are required, one point is lost per restart.
The CogOne of the best examples of a Rube Goldberg machine is the Honda Cog Commercial. Use your favourite search engine to find and view it.

Safety

Safety Considerations for Rube Goldberg.

  1. Machine Base – The machine's support or base is stable enough to:
    • Safely support the machine.
    • Prevent structure movement.
  2. Electrical
    • All exposed electrical connections are guarded or insulated to prevent contact.
    • Electrical power cords are free from hazards, such as abrasion, fraying and pinching.
    • The maximum voltage used is 12V.
    • Wet cell batteries such as car or boat batteries are not allowed.
  3. Rotating Parts.
    • There are no exposed rotating shafts, belts, reciprocating parts or other mechanisms that could cause injury on contact.
    • Protective guards are installed to protect operators and spectators from accidental contact with projecting or flying parts.
    • Flying objects – balls, other objects – do not have enough momentum to escape the machine's confines and injure operators or spectators.
    • Stationary items that project from the machine and that might cause accidental injury are shielded.
  4. Chemicals/Liquids/gasses
    • There are no chemicals used that might injure operators or spectators.
    • There are no open flames used, covered or uncovered.
    • An uncontrolled release of any chemical is not possible.
    • Liquids cannot accidentally contact electrical components of the machine.
