What was the most fun experiment you’ve done?
We’ve done all manner of experiments. We looked at the subject of non-Newtonian liquid on Brainiac, which we covered in Can You Feel the Force?, by walking on custard and it’s an experiment you can do at home using corn flour and that again is saying it’s fun – I’m not saying you’re studying for an exam in it but I would love it if you read Can You Feel the Force? and came away from it with an enthusiasm for Physics. You co-present Top Gear on the BBC… As a scientist do you feel worry about the environmental effects of car emissions given your love of cars? It’s such a massive argument – I think people imagine we take it for granted and don’t think about it on Top Gear but of course we think about it. Cars have an effect on the environment but how big that is compared to other things we don’t know. What proportion human beings have on things like global warming is up for debate – you’ll find scientists arguing for either side and every time it’s addressed by whatever side, it’s address
