Watch Sleek Geeks online: Episode 6 Why is it so 2

Back by special demand, Karl and Adam take on yet another episode of answering questions from the studio audience and the website. In this edition Karl and Adam tackle questions about what’s in water other than water? How do you win Lotto (or why you can’t win Lotto)? Why the sky is blue? And what happens to your body when you go under general anaesthetic? Karl conducts a test to see if black cars get hotter than white ones when left in the sun. Karl and Adam try to work out just how strong eggs are by getting Adam to stand on them. You’ll be amazed how much weight they take. Ruben demonstrates what happens when something very hot hits something very cold, by pouring boiling water into liquid nitrogen. A question sent to our website asks “If our body renews every seven years why don’t we look like second-graders?” Karl explains that a new discovery, which is an unexpected side effect of a spike in Carbon 14 from nuclear explosions, has shown that different parts of our body renew quicker than others. Karl explains why the uterus is his favourite body part.
