　　With British kids now spending less time outdoors than prison inmates and being heavily supervised most of the time, Chris and Xand van Tulleken create a test of independence for their British Planet Child kids, to see if a group of 4-7 year olds can cross London without their parents, using London transport and take a trip on the London Eye. As the children get more tired, will they be able to complete the experiment?
