Help me inspire a bunch of teenagers

I’m involved with a community youth project that runs live music events for teenagers; typically, half a dozen teenage bands/singers (mostly rock) will each play a short set; then there’s a fifteen-minute interval while the next band sets up - each band is interviewed in ‘the green room’ and this is relayed to a big screen by the main stage. Between 250 and 300 young people are in attendance.
The event is run by a branch of the Anglican Church, but this isn’t an cycnical attempt to win converts; it’s very much an attempt to provide something meaningful and worthwhile to do for the young people of this particular area. There is a charity aspect to it and the profits are being directed (with very little lost through administrative overhead, I might add) to a number of worthy causes.
Interstingly, it’s also strongly supported (materially and fiancially) by the local police, because it has been recognised as a positive influence.

My job is to provide stimulation during the intervals; in the fullness of time, this will include stand-up comedy on the main stage, but for the next event, it’s going to be music and video.
I’ve got a good, entertaining selection of music videos that I plan to use; there will also be some powerpoint-type presentations covering the charity work (ranging from hard-hitting statistics, to success stories about what the money raised so far has been used for). I don’t intend for these to be too lengthy or preachy, or they lose their impact.

But there’s also a call (I think) for content that is just generally stimulating, thought-provoking, uplifting, inspiring - and it’s this that I could do with suggestions on. I’m thinking of things along the lines of - but obviously not the same as that ‘trust me on the sunscreen’ thing (which, although it quickly became tiresome, was pretty damn good the first time of hearing). Of course I don’t want it to be patronising either.

Any suggestions? I should probably add that, because this is a Church-sponsored initiative, traditional constraints regarding language, ethics and morality apply - I see no sense in pushing these boundaries, as it will just get me thrown off the team - I’d rather find a way to work usefully within them.

Something like the Powers of Ten video?

It’s an amazing piece and only about 10 minutes long…

Grab a few of the kids and get them to help you out.

It might be possible to get the kids on board later on (and it’s an idea with great merit - we do have the wherewithal to produce quite decent amateur film productions - so there’s no excuse not to), but there are all sorts of logistical and ethical hoops to jump through before we get there.

What I’m searching for is something… without wanting to imply that teenagers are stupid (and indeed, this crowd seems generally fairly smart, orderly and sane)… I guess it’s just the fighting ignorance thing - I’d like to be able to produce something that just makes one person stop and look at the world differently (in a good way).
