Kiell relies on the cameraman's watch
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Kiell initially considers the sundial, but realises that he has no idea how to use one. He then finds the mirror with the extendible handle, and uses it to sneakily peek at one of the cameramen's watches. Unfortunately for him, the camerman eventually catches on to this, and removes his watch, leaving Kiell time-blind. His list of words includes 'profiteroles', 'balloon', 'crisps', 'crest', 'dress', 'cross', 'point', 'course', 'badge', 'lose', 'vet', 'mice', 'shoe', 'clap', 'egg', 'wet', 'cat', 'dog', and 'hat'. In the studio, Alex reveals that Kiell left the caravan after 24 minutes and 20 seconds. However, he also reveals that Kiell had written the word 'course' (with six letters) after the word 'point' (with five letters), and the word 'mice' (four letters) after the word 'vet' (three letters), and also that he'd only included 39 words in his list. He is therefore disqualified from the task on multiple counts.
