Cinema Science - Special Effects in films

Part 4 of 4 lessons on the science of the cinema. Making some special effects using chemistry and physics. I plan to film these then use movie maker to make a 'film&' of all the special effects set to music to show them in the next lesson e.g. fire-writing set to Harry Potter theme music, flaming bubbles to Prodigy&';s firestarter, lightening to the X-Factor theme etc. End of term fun or to fit into other topics.
