BS: What was the Science Theatre modelled on?
DB: It was actually modelled on the Royal Institution in London. The actual shape of it and that was actually modelled on that. And it's - an ideal situation because if you stand in the right place where ever people are sitting they can usually see most of what's going on. Because of the size of the space down the bottom and some of the equipment we use it's not always possible for everybody to see everything but what you've got to try and do is make it as obvious as possible to everybody. And by the way you use the props or move the props around you're actually trying to get them to see everything. So if you, if people are sitting in the front you do an experiment there you tend to do it there and there as well. If they, if you think it's, you know, not visible for them. So it's using the techniques to try and make sure everybody sees everything that's going on because it's really frustrating if you're sitting up in the corner and you can't see what's going on. But in some of the things it's unavoidable because of the actual design of the walls and things. If somebody's sitting right up in the corner and you've got something down in this sort of side of the science theatre, sometimes they're not going to be able to see - all of what's going on. But the important bit we always try and get so it's visible from where ever people are sitting.
