Who should have won the nanobowl contest?.?

We had an entry in the contest: APS Nanobowl - Momentum. We sent an email to Physics Central after the contest, to see if our entry was not selected as a finalist due to some sort of error in the physics. They said my entry was accurate, but lacked "creativity" that the winner and other finalist contained. They also said our entry was only about momentum, and a lot of other entries used momentum. I thought ours was decent, for a concept produced and written by a 13 year old. I did the editing and special effects. But, age should not matter. If you had an entry, you may just want to ask them if you had any errors in the physics. It would be hard for them to select a winner that had technical errors in the physics.
