British commercial vehicle manufacturers played a key role in bolstering Britain's economy throughout the 1950s, especially during the period of postwar austerity, a time when they contributed to the all-important export drive. British lorries were the workhorses of the world, and performed a wide range of tasks from goods delivery to heavy haulage. This highly visual study of British lorries of the 1950s captures, in 120 illustrations, the vital but often understated duties that were reliably conducted 365 days a year. Vintage black and white, and color photography include evocative publicity material, and pictures from the preservation and heritage scene. The comprehensive text reveals much about the marques that were household names, along with information about Britain's road haulage and commercial motor industries.

There’s no need for expensive, high-tech lab equipment to conduct chemistry experiments—you probably have all you need in your home junk drawer. Turn an old LED flashlight into an Energy Drink Tester using aluminum foil and electrical tape. Mix cornstarch and water to make Non-Newtonian Goo. Use a 9-volt battery and thumbtacks to break water molecules into hydrogen and oxygen. Create edible Sweet Crystals from a saturated sugar solution. Or construct your own Three-Penny Battery from galvanized washers, pennies, vinegar, and scrap cardboard. Here are more than 50 great hands-on experiments that can be performed for just pennies . . . or less. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated—atoms, compounds, solutions, mixtures, reactions, thermodynamics, acids and bases, and more.
