Engineering enthusiasts from around the UK must battle to create the most ingenious contraptions using everyday objects in Richard Hammond's Crazy Contraptions. Teams of contestants will go head-to-head to build their own Chain Reaction Machines. With contestants having access to a workshop and purpose-built home environment to test their invention, they will be given the challenge each week of designing, creating and showcasing a new construction, before being judged based on their ingenuity, design and build-quality.

Orkney - seven miles off the coast of Scotland and cut off by the tumultuous Pentland Firth, the fastest flowing tidal race in Europe - is often viewed as being remote. Yet it is one of the treasure troves of archaeology in Britain. Recent discoveries there are turning the stone age map of Britain upside down. Rather than an outpost at the edge of the world, recent finds suggest an extraordinary theory... that Orkney was the cultural capital of our ancient world and the origin of the stone circle cult which culminated in Stonehenge. In this new three-part series Neil Oliver, Chris Packham, Andy Torbet and Dr Shini Somara join hundreds of archaeologists from around the world who have gathered there to investigate at one of Europe's biggest digs.
