This would be a fun contest to enter!

The 2010 Trash to Treasure Competition challenges kids, ages 5-19, to recycle, reuse, and re-engineer everyday materials into out-of-the-box inventions. Three winners will win a trip to Boston to see their designs built and appear on an episode of Design Squad. Twenty-five finalists will be featured on the series website and will receive a Design Squad t-shirt. Entries will be accepted through September 5, 2010 at pbs.org/designsquad.
