BS: So which is your favourite exhibit for the summer theme? Your personal favourite?
DS: I think the racing one is fun but, I actually, in terms of what I think is a great exhibit, I think the See the Light, which involves two light bulbs, one's energy efficient one isn't. And you have to turn the handle to power them. I think that is a great exhibit. But from what I was saying before about the fact that - firstly the - the visitor really doesn't have to read the label as long as they notice that the one is so many watts and the other's how many watts as well. But it's- they actually are feeling how much power it's taking. So, the fact they have to turn the handle the fact that it's really hard to push for the for the inefficient one. And that fact it's really easy to power the other one, it's like you've - made the point very clearly in their minds. Which one's easier to work, well, you know, in that case these ones are going to be a lot easier for - if everybody had these - for the power, for the people generating power to work. So I think - it gets its point across very clearly. I think that's a very good exhibit in terms of that.
It's interesting because we did that exhibit before for the - for the sustainability theme but we didn't do it with a generator we did it, you pressed the button and you have two little dials? And that's fine but it's actually a bit dull. You press the button "Oh yeah, OK, so that one uses up loads of power. That one doesn't." But ith this one it's - it's just taking that exhibit one and - and made it more interactive, I think. Because you're actually having to feel how hard it is to, to power this bulb.
