Overview: Jason Bradbury and Pollyanna Woodward head for the Brecon Beacons to test some of the latest electronic vehicles. How will they stack up against the demanding terrain and could a new car hire scheme revolutionise the way we travel? Next, the pair head to Skegness for a day by the seaside, each armed with a smart camera: complex devices that make most digital cameras look old hat. To round off the holiday fun, Bradbury builds his own version of mind-control game Mind Over Melon and invites people to blow up watermelons using just their brainwaves. What could possibly go wrong?
