The 'Tested to Destruction' segment returns for another adrenaline-charged outing. Suzi and Pollyanna take a fast car and some powerful guns in order to subject seven tough gizmos to some extreme situations - all in the name of research. Elsewhere this week, Jon and Polly take a day trip to France to test some compact cameras. The latest models on the market come complete with interchangeable lenses, but can the tourists figure out how to use them to their advantage? In this episode's challenge, Ortis and Jason venture into the office in a bid to transform the bland environment into a fun, productive space - using only their own gadget ideas. The boys enlist a top design agency to help them on their quest, and add flair to their new concepts. Finally, Jason runs down another top five. This week, he turns his thoughts to gadgets that revamp old technology and give it an entirely new purpose.
