P.S.
Ask your principal if the school has access to a projector and player, if not ask your parents. We have one family in the neighborhood that sets up a movie every year at halloween for the kids to stop and watch and dig through their loot. He uses his projector and sets out a big white sheet over his fence as the screen. Works great and the kids love it.
Sounds like a great job for a techie dad!
Good luck
