BS: Are there any exhibits that you feel need a helper in order to achieve their full potential?
JC: Chromatography. Um - there's no exhibit that can't be enhanced by having somebody there to talk to and work through it. And actually get people - it's talking predominantly about children to get them to actually think about what they're doing rather than do it and they - um (4.7) I don't think there's anything else that - well that one Circulating Circuits I suppose that - they both benefit from actually getting people to use them and that's having a helper there. I wouldn't say there's anything else that specifically has to have somebody with them although - they'd all benefit.
