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.
