The book contains over a hundred exciting and entertaining experiments from the fields of mechanics, optics, acoustics, chemistry, and biology – or more specifically: invitations to see, touch, hear, smell, and taste, with plenty of amusing and surprising elements. Most of them can be replicated and made at home. However, the workbook also briefly introduces and describes recommendations for experiments or games that can be purchased from specialty stores. It is aimed at curious children and adults of all ages.
