Our local middle school has a "high interest day" once a year where a bunch of different, interesting "classes" are offered to the students. The students can select a few that are of interest to them and then they attend the "class". It ranges from cooking to technology to photography. One of the teachers that knows me asked if I'd be willing to bring in a game, give a quick history of pinball, discuss how the games work, show the inside of the game, etc., and then let them play. I was thinking we could let everyone play a bit and then have a one-ball tournament with the high score getting some kind of prize.
I think this is something I'm going to do as I think it would be a lot of fun.
