A group of 49 students will leave Hong Kong tomorrow for the Odyssey of the Mind 2005 World Finals, which will be held at the University of Colorado in the US from May 21 to 24. The Odyssey of the Mind is an international educational programme that sets problem-solving challenges for students from kindergarten to university. They must use their creativity to complete tasks that range from building mechanical devices to presenting their interpretation of dreams. In the Hong Kong competition, teams of seven students were asked to solve one of the four problems designed by the US organisers. They had to work within a budget, so they also learned about money management. The winning team in each category and age group will represent the SAR in Colorado. A team from Assembly of God Hebron Secondary School, competing in the Crazy Columns category, came up with a 15-gram balsa wood structure that can support at least 90 kilograms of weight. 'We had $975 to spend on balsa wood and glue,' the team said at a press conference. 'We observed the structure of many skyscrapers and concert stages and carried out numerous tests - some of which were done with the help of the City University lab.' 'We are still trying to improve it and make it support as much weight as possible. 'It is the first time we will take part in the world finals. We'll try our best and, at the same time, learn from other teams from around the world.' Both King Ling College and Ho Lap College will compete in the Stunt Mobile category. With slightly more than $1,000, each team set out to design, build and run two original vehicles that would travel over obstacle courses and eventually burst a balloon. Marymount Secondary School and STFA Lee Shau Kee College will take part in the In Your Dreams category, which required them to create a performance that includes three dreams - cheerful, non-sensible and nightmarish. The nightmare drama features a monster, designed and built by the team, that will change in appearance and perform various tasks. Competing in the Classic . . . Get the Message? category, Creative Primary School and Pok Oi Hospital Chan Kai Memorial College will present an original performance that tells the same story three times over, using primitive, evolved and futuristic methods of communication. The play will include a narrator and a stage set. 'Hong Kong students are good at problem-solving,' said Lau Kwok-leung, the head judge for the In Your Dreams category in the Hong Kong selection competition. 'They are generally very creative and quite sophisticated when it comes to stage and props production. It is not easy given the limited budget.' Last year, Munsang College (Hong Kong Island) came second in their category with a ball propeller called Strategy Sphere.
