Class 4S are taking a coach trip to Alton Towers. Or are they? Tricia seems to think otherwise, and convinces her classmates that they're really journeying to the centre of the Earth as part of an experiment by terrorists, who are robots made to look like Simon Cowell. It's all part of The Spirisy, apparently, which their form teacher, Miss Sheehan is part of, not to mention the Nasties, the Arabesques and the Funny Mentalists. School Journey to the Centre of the Earth gives a hilarious insight into an eight-year-old imagination and casts the world of adults in a whole new light It was commissioned by the National Theatre as part of the Shell Connections Festival in 2006 and can be performed by 15 young people from Year 6 upwards.
