x-change at the festival
NOISEmaker Amanda Chmura casts a chemical spell over the audience at the 2007 BA Festival of Science in York
Each evening at the British Science Festival, join a panel of the day's speakers to review the 'best of the fest'.  Unwind, have a drink and get your teeth into some of the hottest topics and current issues that have been raised during the day.  Exchange your views with the panel and other festival delegates.
