In a cool and unusual Christmas episode your favourite science buddies are chatting through the logistics of running your own toy factory in the North Pole. Laura has her hard hat on, and her clipboard ready, as she fills the role of foreman for the Pole while Ron feeds her wild and whacky decisions into a special spreadsheet that he made to calculate the numbers.What Christmas obviously needs more of is spreadsheets, because nothing says Merry Christmas like a Match Index function.More Christmas next week as well so plough through the advent calendar, open the eggnog and have a lovely time with Lexx Education.
