Amazon.com description: Product Description: An introduction to chemistry for children, this book shows how to perform simple experiments using everyday materials like jars, frozen food trays, plastic cups and spoons, salt, water, sugar, vinegar and baking soda. The principles of fermentation and osmosis are demonstrated by making a batch of mouth-puckering pickles, and making a fizzy-drink bottle flip its top. Learning about positive and negative-charged molecules by making marbled gift wrap, and making a silver cleaner that is really an alectrolyte solution, are some of the practical projects illustrated in this book.
