BS: What do you think will motivate them to try another exhibit or how do you think they decide?
TS: Kids rush about. If you've got a group here then the kids are the ones who bore most easily and rush to something else. So that often takes the group to another exhibit. I mean it is a very random pattern. We've done some tracking exercises and that is pretty much what happens. That is, the kids are the scouts, in the thing. That is, they go to something and the rest of the group moves there. Sometimes mum wanders off to something else but more often than not it is the kids who will sort of, guide in a very random walk sort of way, the group through the exhibition.
