Speaking of kids, a couple years ago I did a 'how to play pinball' seminar for some high school kids.
This high school is one of the most expensive in the area (20k/yr). Part of their curriculum is that for each semester, a topic is chosen and then they immerse themselves in it. The idea is to get kids to "dig into" a topic, because our culture and learning tend to be so skin deep these days.
The teacher is a friend of a friend who is an op, so the topic wound up being pinball.
He and a couple other ops supplied games. One op covered history, another covered basic mechanical stuff and I did the how to play seminar.
In the captive audience environment, the kids got really into the games. They would even eat lunch in the classroom with the games to play more and had to be kicked out when the next class needed to start. There were only 16 kids in the class so I decided to organize a round robin tournament that they could play out through their remaining sessions.
I know some people have loaned games to their kids' school. Potential "ins" are fund raisers, science experiments (lots of possibilities with math and physics), and single dad trying to meet a hot teacher.
