The Maryland Science Center's Beyond Numbers exhibit has done a good job of encouraging social interaction among its visitors. The double pendulum on chaos is a good example of how the design intentionally does this: It would have been more illustrative of chaos to have the two pendulums hanging from the same axle and have some sort of trigger to start them at the same time. (and I'm not sure about the more illustrative thing - it could have created a misconception). But if two pendulums were side by side, but too far apart for one person to reach, it would take two people to "work" the exhibit - better yet, three - one to say "ready, set, go". Many other exhibit components had this "social conscience" to their design. After watching my 73 year old father enjoy the exhibit with my 12 year old niece, I personally think, the best feature was the "two-butt" seats - and lots of 'em. Cathy Who's not working there any more, but is still proud of that exhibit
