Each book in this series follows a packet of energy along a journey.
Each stage of the journey is described in a short chapter, and we learn
what alternative paths the energy might have taken along the way. This
book shows how sunlight is turned into a movie. It explains what happens
when the sunlight reaches Earth, how its energy is stored in fossil
fuels, how this energy is then released in power stations and used to
generate electricity which is used to make light, and finally how this
light is used to make a movie. The topics covered are illustrated with
experiments, amazing facts and scientific discoveries.
