Summary: It's Christmas, and we're celebrating in style with a look at the science behind the things that grace the festive period. In a special programme recorded live in the kitchen, we produce our own home-made ice cream, hear about the brain-basis of the Boxing Day sales bargain, test fruit-fuelled flamethrowers, investigate candle chemistry, find out about LED fairy lights, probe the origins of the Star of Bethlehem, and make our own hydrogen-powered party popper. Merry Christmas!
