Bang Goes the Theory

Jem Stansfield puts spider silk - the strongest material in the natural world - to the test; Liz Bonnin joins the RAF's flight school to find out the truth about multi-tasking; Dr Yan Wong experiments with sodium acetate; and Dallas Campbell dusts off his top hat to reveal the secret science of magic. The programme is co-produced with The Open University.
