This program focuses on the components of our sense of balance. Stunt coordinator Marc Cass demonstrates how the balance organs inform us of how we are moving. At the Circus School, in San Francisco, a troupe of acrobats illustrates how eyes control balance by calculating what our bodies are doing in relation to the outside world. Dr. Ros Davies, from the National Hospital for Neurology and Neurosurgery, examines why alcohol consumption worsens balance. The cause of seasickness is also discussed, and a trip onboard an infamous roller coaster, the Russian Vomit Comet, reveals the "why" behind the sickening results for first-time riders.
