Possible story ideas;
1. A child in a workhouse/factory is trying to explain something has gone wrong and wants to alert the master. As he isn't allowed to speak while working without being punished he has to try and come up with a new ways of communicating such as miming/cue cards. After the master fails to understand a crash/explosion occurs behind them and the child runs off before he gets the blame.
(Would be set in Victorian Era workhouse/factory)
2. Day to day life of a child working in a factor and following their journey. Starting off happy/nervous but as the days go by the child becomes more and more part of the machine and less childlike with no voice at all about working there.
(Could be set in either Victorian Era or modern times)
3. Scientist working in a laboratory with chemicals while his child/children play noisily behind him. The noises keep making him nearly spill his work and distracted by the noises behind him he over-pours a chemical and results in it exploding in his face. So that he can get peace and quite while trying to work he makes the children sit still on a stool behind him while he declares children should be seen and not heard.
