Series putting science to the test. Jem Stansfield puts his life in his hands by tying himself to a water jet pack, while Liz Bonnin finds out if insects are the future of food.
In this second episode of the series, the team take on more scientific challenges. Engineer Jem Stansfield designs, builds and then puts his life in his hands by tying himself to a water jet pack.
Zoologist Liz Bonnin finds out if insects are the future of food, science-mad Dallas Campbell investigates NASA's latest attempts to prove there is life beyond Earth, and roving reporter Dr Yan Wong challenges the people of Cambridge to blow up a bin liner.
The programme is co-produced with the Open University.
