BS: Can you give me examples of the different types of audience reactions that you get?
JC: There's a demonstration in - the schools material show where you use liquid nitrogen. And you use it to freeze a flower. And you get very very different reactions. You tend - yeah, on the whole again it's probably - the boys think it's great - and you can equally the see - you can see other people being quite upset that you've actually killed this flower - and that that creates - that that gets different reactions. Um - haven't done public shows for quite a long time. ((long pause)) Trying to think. Thinking of specifics is quite difficult.
