The Demonstrator is showing the audience a kit for making your own robot. To demonstrate how far advances this model is, he exhibits various earlier models but is increasingly interrupted by a voice in th audience, who could be the 'plant' he arranged to ask intelligent questions or who could be a Government agent sent to discover who is selling robots tot he public - a practice that is not allowed. After each robot is shown it is asked to go bak to its box, and then pull the lid down. At then end of the demonstration the Demontrator is asked to go back to his box and we, the audience, are also sent back to our boxes!
