Going out with a bang – the lazy men cook xmas dinner. Our black box takes on a scrapyard crusher. Viewer Dan Crossley gets a surprise visit from the Brainiac babes. John Fashanu has trouble when it comes to inhaling helium. Can you catch a cold from... (more) being cold. Jon Tickle builds his own home cinema projection system. We find out how long it takes from being drunk to being sober. The conclusion of Tall v Small. And when science goes bad - the bits you don’t normally see.
