BM: At one point you talk about a hands-on interactive as opposed to a computer interactive and I'm wondering how you see the difference there?
ER: Right, I I see the difference as, something where - somebody who is going up to an exhibit can actually - interact, hold it, pick up, physically get involved with the exhibit. For example the Bernoulli Blower. I'm trying to keep the same examples rather than giving completely different ones, they can pick up the ball and they can knock ball off the fan they can then pick it back up again and put it there. They can stop the fan with their hands. They can try and move the ball without touching it. They can experiment with it, they can play with it. A computer interactive tends to be, maybe a touch screen where they are - choosing options or pressing buttons - all relating to the screen which gives them information or maybe asks them questions or for, something like "How Many Like Me." I would see that as a more computer based interactive, although they do get them to smell freesias and to do physical things as well so it's asking you which way do you fold your arms is it left over right or is it right over left? So they are getting involved physically and then they're pressing the button. So that's not - exactly what I mean by a computer interactive. Ooften - they don't have that physical interaction at all the don't, or there's no physical element to it, it just - is - you - moving things around on a screen. Or - making decisions and choosing. Which, which is also interactive, it's also interaction and - is also better than - kind of - just having a label. There's nothing wrong, I'm not saying that computer interactives are bad things um because I don't believe they are. But I believe they're different.
