In our second episode, Liz looks at the positive and negative effects of the skin pigment melatonin, pondering its evolutionary role in allowing humans to populate the darker northern areas of our planet.

Dallas attempts to prime the minds of every one visiting the science museum, not only to make them change the speed at which they walk, but to temporarily improve their cognitive function.

Dr Yan manages to override both the body's vestibular system and muscle proprioceptors, by playing with people's vision – to the point where they fall over! And Jem re- invents the wheel, with the help of a few equations and some catenary curves.
