Roadshow 2009
Bang Goes The Theory welcomed 65,000 people from across the UK to its live events. Together we proved that science is fun, and we're going to do it again in 2010 - see below for details.
Dallas free dives

Pudsey in space
Bang Goes The Theory helps Pudsey take things to the limit for BBC Children in Need (bbc.co.uk/pudsey). Is that his breath on the lens?
