BM: Another thing as well, again something you've mentioned in passing is the role stressed on interactive and hands-on science - a little bit about what the importance is of that.
HF: Of hands-on? That's the most fundamental part of a hands-on science centre is that it's hands-on. The theory behind it is that if you - if you engage with something if you do something you're much more likely to remember it. You know, there's a classic bit of - there's a pyramid, or triangular shape of how much you, you remember. If someone's told you something, you remember about 10% of it. If you've written it down you remember 30% of it, you know. And the more actively you engage in it the more, the higher percentage of the stuff you remember. So a hands-on centre the theory is, is that because you're physically engaged with something you learn about it. And that's the the "hands-on minds-on" statement that I mentioned that comes from Richard Gregory. Who is the guy who did the very first science centre in the UK. He was the person who founded the Exploratory. So, it, you know that comes from him and he's, that - that's his philosophy - it's the single most important thing that we do. It's the, that's the foundation for the whole movement - as it were.
