The Ghost at the Machine
In the first of a brand new series of nine programmes, three teams are given a most unusual challenge. It is the aftermath of an office party and a secretary asks them to type a message on an electric typewriter-only there is a problem. The typewriter is in a locked room so all the operation has to be done through the keyhole.
The teams have three and a half hours to build devices that will accomplish the task, then only one minute to amaze the studio audience with their typing abilities.
