Why Things Go Wrong

There are some days when mechanical things can just drive you crazy - like the car that refuses to start when you're already half-an-hour late or the phone that only gets wrong numbers or the key that sticks in the lock or the tap that won't stop dripping.... What can we do about them? Tim Hunkin , ex-engineer, inventor and Observer cartoonist, has his own ideas. In this programme, with the help of a mechanical barman, a flying sheep, some gunpowder and a DC10, Tim looks at machines and suggests, with his own animated cartoons, ways of making them more reliable.
