Watch Sleek Geeks online: Episode 8 Weeing

So what actually happens after you drink a glass of water? How does it come out the other end? We follow liquid through peristalsis all the way to the bladder. We see a remarkable X-Ray of a bladder emptying and amazing footage of the urinary tract. Adam visits a work site to show a Urine Colour Chart - the chart is used so you can tell if you're dehydrated by the colour of your wee. We demythologise the must-drink-eight-glasses-of-water-a-day belief and discuss the existence of embedded water in food we eat. We also explore the myths that you should wee on a jellyfish sting and that there is a burgeoning market for stolen kidneys. We discuss breaking the seal and stopping midstream, exploding kidneys and how much elephants can wee. Karl claims men have to splatter, and that the same reason men splatter is the same basis for the technology that creates ink jet printing. Ruben uses drain cleaner to make flammable bubbles, it's just up to Adam to set them alight before they blow away. Adam explains why some people's wee smells of asparagus while others doesn't. A group of Australia's premier performers, including Deni Hines, Iva Davies and The Chaser's Andrew Hansen and Chris Taylor collaborate to produce a moving tribute to micturation 'Wee Across the World'.
