Former Top Gear presenter Richard Hammond's Channel 4 series Crazy Contraptions, which was the star's first programme on the channel, is understood to have been shelved by the broadcaster after one series.

The series first aired on Channel 4 last Spring on Friday nights at 8pm. Due to low ratings, the show was shifted to Sunday nights at the much later time of 11pm. Unsurprisingly, ratings did not recover and now the show has reportedly been shelved.

Each episode sees teams of contestants go head-to-head and build their own 'Chain Reaction Machine', with mechanisms that are made from everyday materials that complete basic domestic tasks in the most complicated way possible.

Contestants will have access to the workshop full of purpose-built resources. Once complete, they will be scored by the judges based on the contraption's ingenuity and quality. At the end of the episode, one team of contestants will be eliminated from the competition, leading to a champion being crowned in the final episode.

Richard Hammond's Crazy Contraptions is available to stream on All4.
