As a finale to Science Week, Howard Stableford, Shahnaz Pakravan and Philippa Forrester invite the country to join in a night of experiments from Tomorrow's World Live at Birmingham's NEC. Viewers are asked to take part in a national phone-in to find out what part psychology plays in affecting a jury's verdict. Plus a look at whether left-handed people are more talented than right-handed, and a battle between Britain's robots.

Science Week culminates in the world's largest interactive experiment, transforming the United Kingdom into a giant laboratory and inviting viewers to contribute their observations.

In front of an audience of 750 at the Tomorrow's World Live event at the NEC in Birmingham, the show puts the legal system on trial, asking whether psychological factors influence juries. There is also the result of a survey of the red squirrel population, to see how they are faring in competition with grey squirrels. The third experiment will try to unravel a mystery involving genetics, evolution and the brain, to discover whether left-handed people are more talented than right-handed. And there is also a robot mouse contest in which the computerised rodents race to the centre of a maze.
