Raisins are dried grapes. They are produced in many regions of the world, such as Armenia, the United States, Australia, Chile, Argentina, Macedonia, Mexico, Greece, Syria, Turkey, India, Iran, Pakistan, Iraq, China, Afghanistan, Togo, and Jamaica, as well as South Africa and Southern and Eastern Europe. Raisins may be eaten raw or used in cooking and baking. Wheatpaste (also known as potato paste, flour paste, rice paste, Marxist glue, or simply paste) is a liquid adhesive made from vegetable starch and water. It has been used since ancient times for various arts and crafts such as book binding, decoupage, collage, and papier-mÃ¢chÃ©. It is also made for the purpose of adhering paper posters to walls and other surfaces (often in graffiti). Closely resembling wallpaper paste, it is often made by mixing roughly equal portions of flour and water and heating it until it thickens. A similar flour and water formula is taught in elementary school minus the low heat simmer as an easy substitute for ready-made adhesive.
