Three Long-term Problems have been selected out of those designed by the Creative Competitions, Inc. in the United States for the 2004 Hong Kong Odyssey of the Mind Competitions. The following are the synopses of each problem:

Problem #1 <Envirover>

The team's problem is to build and drive a human-powered Envirover vehicle that will collect trash and deliver it to a Factory, where it will be used to manufacture a product of the team's design. The team will present an original prototype of the product then use the trash to produce five samples of the product. The team will also create and present a humorous sales pitch for its product that takes place in a store setting.

Divisions: II & III Cost limit: HK$ 1,053

Problem #2 <Strategy Sphere>

This technical problem requires teams to design and build two devices that will mechanically propel balls through a circular hoop. The location of the devices will determine the value of the points scored when the ball passes through the hoop. Teams will also create a device to retrieve the balls after they are launched. All aspects of the problem solution will be integrated into a theme about how a change in the Earth’s geosphere affects the Earth’s atmosphere.

Divisions: II & III Cost limit: HK$1,053

Problem #3 <Classics... Fantastic Art >

In this problem, teams will create and present a performance that includes works of art that come alive when no one can see them and return to their original state when others are around. The team will make four works of art: two will be replicas of works by artists from a list, and two will be original works created by the team. The performance will include at least one scene where the works of art come to life and interact with each other. The performance will also include a character that is not part of the works of art.

Divisions: I & III Cost limit: HK$975
