December 19th, 2006

Episode 49 of 1056 episodes

In the final show of 2006, Chris, Dave and Kat answer all your science questions including why poppadoms curl upwards in the pan, how seedless grapes grow, and if lightning really does strike twice. To celebrate the coming of Christmas, Colin Humphries joins us to explain the astronomical phenomenon behind the Star of Bethlehem, and in Kitchen Science Derek Thorne and Alicia Webb knock back a few shots of vodka to find out how breathalysers catch drink-drivers. In the second part of the Science of Colour series, Anna Lacey finds out about the history of mauve and how hair dye conceals those dreaded greys.
