Taskmaster: Prepositional Phrases

A third addition to our ideas for the classroom that have come from the television program 'Taskmaster'.

Room for interpretation in the prepositional phrase? Greg Davies thought so. 

Can you set you children a similar task and look for scope within the prepositional phrases involved to carry out the task in 'their own way'?
