BS: Can you tell me a little bit about the importance of interactive hands-on science,
JC: It just means more if you do it yourself. - Everyone's been there when somebody's stands up and tells you all about and then you "Oh that's really good" and then you go and shut the door and it's somebody talking at you. Whereas if you've actually done it and you've made the sound and (all the rest of it) and actually created the experience for yourself then you have much more memory of it. Just means a lot more, it makes it more personal.
