Physics teacher Mr Smith embarks on a special project to use fireworks to inspire a new love of science in a typical class of 13 year-olds. But from the start things don't go to plan.

Mr Smith organises a trip to China to see fireworks made. The Royal Artillery help stage an explosive physics lesson. Then the class have to help design and build one of the biggest displays Liverpool has ever seen.
