BS: When you're on the exhibit hall can you tell me a little bit about how you interact with visitors at the weekend and during the week.
JC: I find it a lot easier during the week. Because children will just come to you. They'll - if they can't do it they'll say "oh what's this?" or "what's that?" Um - and if you can see somebody struggling you can always join in and their friends join in and you also can see them tell somebody else if - you say do Chromatography and you'll do it with a couple of children. Then you might go away but you'll see them go "oh come and do this. I can" - and that's really good. Um - On the weekends -it's more through chatting. A lot of it I find just through talking to people about the puzzles. Often parents will say "oh, how do you do this? I'm going to do this so my son thinks I've done it for myself."
It - it's the puzzles specifically people seem to go for. Or it's talking to people about how things function - rather than sort of explaining how they work because they tend to do that for themselves. Or prefer to do that for themselves. Particularly dads - who like to ((laughs)) - they do like to do that themselves. And I've seen mothers avoid the exhibits and avoid people. That sounds terribly sexist. But the - it seems to work that way particularly.
