Hello! And welcome to the x-change 2012 - the highlights show from the British Science Festival in Aberdeen.
The British Science Festival is organised by the British Science Association. The x-change is run by a team of dedicated volunteers who spend each day selecting the best speakers from all corners of the British Science Festival and bring them together for the x-change; a fun, fast run-through of the best, funniest, most controversial and most interesting speakers from the day.
One of the highlights of the x-change (making it a highlight of the highlights!) was the Demo Spectacular. Featuring cereal boxes, smoking jelly babies and strategically-placed electric shocks... It's time to button up your lab coat and put on your goggles as we take a look at the biggest demonstrations and experiments from the British Science Festival...
