BS: could you say a little about the difference between the type of interactivity that occurs within the science theatre and the type of interactivity that happens within the exhibit hall.
SB: Yeah. We can't really do very much interactive stuff in the shows - unfortunately. We haven't got enough time. We do try to make shows as interactive as we can and I don't just mean children coming up to volunteer to do things. That's that's only one child gets an opportunity. We like the children to do things in the show. It's very simple things, miming using hand actions and singing and voting with voting cards. Just anything that makes them feel part of it and stops them from dozing off ((laughs) and helps them to feel that they that they have taken part.I think it just makes it more enjoyable all round. So that's what we're looking for. So - yes you said what sort of shows do I prefer. I prefer shows that have more of that in. But it doesn't always - it's not always easy to do.
