From a device that makes sounds waves visible to a unique "pomato" plant, these 100 imaginative and impressive science projects will impress science fair judges and teachers--and astound all the kids in the school. Some of the experiments can be completed quickly, others take more time, thought, and construction, but every one uses readily available materials.
