Dismissing the idea that physics has to be dull, Byrne and Cassidy serve up a rip-roaring science adventure that puts the reader in the driving seat. Is a van containing a bird lighter when the bird is flying or on a perch? Why does the stream from a tap get increasingly thinner? Can you speed up light? Is time travel possible? Featuring a cast of odd-ball characters and a laugh-out-loud storyline, Byrne and Cassidy explain the basic principles of modern science and guide the reader in working out the rest. With thirty stimulating mindbenders of varying difficulty, including detailed clues and answers for each problem, How to Save the World with Salad Dressing is the perfect Christmas gift for anyone with an interest in science or mathematics.
