Demonstrating Chemistry: The Science of Fireworks *suitable for home teaching*

From Teachers TV, this video helps to bring the complex science of fireworks into the classroom. Matthew Tosh shows a series of firework demonstrations which cannot easily be performed in the classroom laboratory, either because they need specialist facilities or on health and safety grounds. The demonstrations include: • flash powder mixes • Chinese firecrackers • rockets • firework fountains. The video shows students the physics of ballistics and the combustion reactions that produce coloured light. Matthew, also highlights the very real dangers of working with explosives and the safety precautions professional pyrotechnics engineers need to take.
