I found this book on a list of best non-fiction books for children and young adults. What a fantastic book! If you have a child (or adult) that loves science, this book is a wonderful resource. Great science projects with very specific instructions and pictures are included and the best part, is the section 'Why does it do that?' which goes into the theory behind the experiments. My 10 year old son loves this book and reads it constantly. Can't wait to get the sequel...
