SB: So I wanted - to have designed - a demo that would show - somehow would show the difference between a big push and a little push. You could actually see a result.
And the idea that we had was um one of these fairground things with a hammer so that if you pushed gently, on it, something would shoot up a short distance. And then if you could give it a really big push, you wouldn't necessarily have to be a hammer it could be a pushometer, something like that, and then it could go up to the top and ring a bell. And to make it a bit of fun and get the teacher out to do it.We haven't really worked it out exactly what it would be. But if we'd have had the time for someone to develop a pushometer for the show, I think that that would have been the wow factor that it could have been something really fun. Or it could have been a balloon that popped if they got it up to the top or. You know, it would have been a way of - introducing the idea of measuring forces in a way that they would remember. For example, in the forces show, at the end, we have a seat of nails. And the teacher has - we say would you like to sit on one nail, one drawing pin and they say no. And then we say would you like to sit on five, would that hurt more. And they say, that would hurt more we don't want to sit on that. Then we produce a seat, a stool, with 800 nails on. And we say what do you think about that? Would that be any better or worse? And the children have a think about that. And then the teacher, victim, teacher, head-teacher sometimes, comes out and sits on this - seat of nails. And the children, the letters that we've had about this, you know. It is the wow factor. They remember that force, when you're spreading it out, then it that's a way of making it a smaller force. You can spread it out over 800 nails and the force was smaller and it is really - that that to me is one of the best examples of what I was talking about having something with a wow factor. Now I haven't really found something as good as that for Pushes and Pulls but that's what I'm looking for. An equivalent. For Pushes and Pulls.
