high-school engineering competition

Between 2012 - 2015 I was one of the three judges for High-school level Engineering competition held by the University of Melbourne. The competition was to design a Rube Goldberg machine, it is a machine with many set of actions  that is deliberately designed to be over complicated to accomplish a simple task. The competition pitted various high school across the state of Victoria in Australia where various aspects of the machine are judged, such as: number of energy transfer, type of energy transfer, aesthetic, number of green/recycled materials, etc. The competition also has an International version, where high school students from Indonesia, Singapore, Malaysia, etc are required to record their machine in action and submitted online.
