This book is a lot of fun! My 7 year old brother and I had a good time picking out and doing the experiments. You can do many interesting things like make toilet volcanoes or even screaming balloons! Some of these experiments take only minutes, while others take longer. Be prepared to clean up though :) The great thing about these experiments is that all of the supplies needed can be found around the house. I think that this book would make a great gift. I believe that this book was geared towards 7-10 year olds, although some of the experiments require adult help. The book itself is well written for its purpose as it is easy to understand and follow along with the instructions. This book will provide hours of excitement. Overall I would rate this book a 4/5 only because I feel that some of the experiments were fillers, but the majority of them were thorough.
