BM: Do you ever target exhibits or shows to a particular gender or to a particular kind of cooperation or not.
HF: No. No. I don't think so anyway. Not that I know of. Certainly not gender based. No. We try and appeal to absolutely everybody. And just sort of taking a step back to sort of if you want to talk about cooperation for exhibits - I think it's - talk about whether there's a problem with an exhibit means you've got to cooperate to work it - um that is a difficult thing because if you're on your own means you can't use it. Which is bad. So - you should make sure that every exhibit can be used by one person alone but, if you can possibly get more people involved then that would be great. Which is why the - you know the Fat Cat racing exhibit that's being talked about that - one person can use it but if 4 people want to engage with it then they can. And things like the volleyball exhibit that's at Bristol, again you know is a team game but if you just want to play with it on your own then you can. And that I think is - and that's probably why that, Circulating Circuits exhibit which you described why that doesn't work is because, you just physically not, you can't get to all of the switches to press them all at the same time so, ºI think that's probablyº why that one failed again.
