Ice and its role in the beginning of life, plus the best way to keep beer cool in an esky. We savour the delights of Adam's urine and bathwater and look at the real story behind rips - what they are, how they work and how you can spot one.
Adam and Karl test their fortitude in flight with the Roulettes and we see what it's like to experience the sensation of zero gravity. As one of the Sleek Geek range of products the Geeks also offer a simple device to avoid ever being zapped.
The Geeks look at men's wandering eyes compared to women's, how early women begin their propensity to talk, and how Leonardo da Vinci really was a dirty old man. Then there are some well overdue facts about picking your nose.
Adam subjects himself to hypnosis and Karl explains dj vu. We also see gorillas in the mist as the Geeks explain how our perception of the world is heavily filtered through a simple test with our studio audience.
