Sleek Geeks

Adam donates the use of his feet in a firewalking experiment and Karl brutally subjects members of the studio audience to hot chillies.

Adam subjects himself to hypnosis and Karl explains deja  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.

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.

The Sleek Geeks examine Einstein's theory of relativity and show that none of us are actually living in the real world, because we're all on time delay.

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.

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.
