Sleep

The Big Question: “Why do bats sleep upside down?” Description: Harrison sets off on an investigation of such sleep phenomena as yawning, snoring, and sleepwalking. Along the way he shows kids how to make other people yawn and how to make it seem like they are fast asleep (with fake snoring!). Viewers get to find out what causes nightmares and how to make bad dreams go away. My Great Challenge: The challengers must have slept in today….there is no great challenge in this episode. In the Field: Harrison explores a sleep lab where he is hooked up to an EEG machine that monitors his brainwaves.
