They’ve got some pretty cool stuff in the trailer: a blue screen and camera for pretending to be a TV weather forecaster (I got a bit too exciting about this!); a metre high tornado (a bit like this one); a professional standard weather station to have a look at; and lots of other cool gadgets and weather demos to play with.
If you want to go along and see the roadshow for yourself, then its going to be at these places:
14-17 March 2011: Newcastle Science Fest
21-27 March 2011: Manchester Climate Week

31 May – 5 June 2011: Cannon Hill Park, Birmingham

More generally, the Big Bang fair was pretty interesting even though it seems to be half way between a careers fair and a science festival. I particular enjoyed the flying silver penguin-esque balloons. No idea what they were for but they were so strange – it almost felt like you were underwater if stared at them for too long!
