The choice of materials is up to your team however you cannot use prefabricated items that are used/designed for air flow/movement/production etc. Therefore, items such as fans, pinwheels, blower wheels cannot be used. Parts from a pre-made wind turbine or windmill kit may also NOT be used.
We encourage teams to be creative in their design. Teams may use other prefabricated materials if they are specifically designed for other uses. The more creative the better! So items like skate boards, curtains, paperclips, scooters etc are totally acceptable. Use your imagination!
If you have any questions about this please let me know.
