Great idea. I very much enjoy the idea of introducing video editing to the younger generation and feel that it would give them a sense of responsibility to pick and choose what they feel is best, not many 13 year olds have much "choices" to make because of social factors so this is a good platform for them.
Cheers dan! the thing is, I wouldn't wanna add any sort of decoration because at the end of it, they're going to have to destroy it! So how it looks doesn't matter, the construction is the main thing in this challenge!
