Bang Goes the Theory - Series 1 - Episode 5

Jem Stansfield attempts to defeat the US Navy's latest weapon with no more than some foam and a crash helmet. Zoologist Liz Bonnin gets in contact with her frog brain, Dallas Campbell re-programmes his caveman brain to become a thrill-seeker, and Dr Yan Wong gets his thrills from inhaling sulphur hexafluoride. The programme is co-produced with The Open University.
