 Experimental science is really the heart of our society. It's an attitude of mine that rejects authority and tries to find things out for itself. And I think this is really important in the modern world because it's full of complicated things that we all need to understand. We're inclined to think that there are these people called experts who will tell us the answer, but we need to be aware that they're finding things out themselves. There aren't always just right answers. And this is a message that we'd like to convey to children. People often think that science is only about things that happen in the lab, but we're trying to point out through the experiments that it's just a way of understanding the world. When you're actually with kids, they're so curious and they're so good at finding things out, but that's when it gets really rewarding. But we know it's something hugely innovative and new that no-one's ever heard of before. It's quite hard to un-push it and you get really messy as well, that's fun. We did the one where you had to stretch the plastic. We had to make a kind of rainbow collar and at the end we got to see it. I'm liking the lab in the right, because we've done really enough fun experiments about light and we've got to know more about it. There's a lot of stuff that people take for granted. They think that there's nothing else to discover in the world with iPods and wireless internet access and things like that. But there's still things to be discovered and we need scientists and we need to get the next generation scientists engaged. I think the lab in the lorry is one of the most spectacular things that the Institute of Physics has ever done in outreach terms and I think that the volunteers and the kids who use it, they really will get connected to science. I volunteered to be on lab in the lorry because I wanted to show people that science and especially physics wasn't just sitting in classrooms deriving equations, it was actually things you can do out in the real world. The students have been able to interact with the scientists that are there. They've seen the scientists as role models. These lorries are just so huge and so beautifully designed. They're just right for the job. It's just marvellous to see this all coming together. Everybody in the path they've taken life has always been one or two people who have been really influential. It could be your aunt who's taken you out with a telescope because a comet is going by or an uncle who takes apart a clock and shows you how it works. And that's what we're hoping that the lab in the lorry will be that uncle, that aunt, that friend of the family who just turned on a light bulb. I thought the lab in the lorry was really good because we got to try out these experiments that we'd never done before and they looked really cool. The volunteers were friendly because they explained it well. I think we can all remember just one incident at school that made a big difference to us and I hope that visiting the lorry will be that for the awful lot of children.
