Genius With Dave Gorman

The stand-up comedian and one half of Baddiel and Skinner, Frank Skinner, looks at the public's ideas.

Ideas

- The bespoke multi-bladed razor head mould, to make shaving quicker: Not genius

- Placing prisoners on exercise bikes attached to the national power grid: Winning genius

- The science of opposites: Not genius
Note: Tony and Stuart's website is www.oppo-site.com

- Dancing maths teachers to encourage greater numbers to study maths: Genius

(Ideas from the reject bin included painting stalkers so they glow-in-the dark; colouring in Frank Sinatra's blue eyes in his black-and-white films; two-in-one shampoo and conditioner; melon-flavoured cucumbers; comb-unders for men who can't grow a beard; and freezer magnets so fridges don't get all the glory)

Red Button Extras

- Extra idea - More masculine umbrellas: Not genius.

- The creators of the science of opposites return for some more experiments.
