This book is not only a life saver, it's amazing amounts of fun. I have a very busy six-year-old who loves to get messy. We've been working our way through this book and have loved all the activities so far. With just some corn meal, corn starch, and vegetable oil we made sand that kept us both happy and playing for over an hour. Asia Citro was a science teacher for years and it shows in the creativity and cleverness of the projects. I loved how easy they are without lots of hard to find ingredients. This would be the perfect gift for any parent whose can't wait to feed the hungry imagination of their little ones!
