Useful for storing food, or for lining hats to keep the alien brainwaves at bay, aluminum foil is a fixture around the world. It is a paper-thin sheet of rolled aluminum that tears easily and can be used to wrap and store food, in art, as decoration, as insulation and in heat exchangers.
First developed in 1910 as a replacement for tin foil, aluminum foil gained popularity quickly. It is not merely seen in home use, but also has many commercial uses. Manufacturers quickly found that it preserved food from bacterial growth, prevented light from spoiling the food, and helped stop moisture from collecting in it. It also does not impart any flavor to food wrapped in it. Many manufacturers use this foil to line drink boxes, thermal bags and other foods.
Aluminum foil can also be used for arts and crafts, especially foil that comes in different colors. In this form, it is also used for wrapping gift boxes and other gifts. Regular kitchen foil has many uses outside the kitchen. It can be used over the mouth of a bottle and the cap placed on it, so the liquid will not leak. It can be an impromptu palette for paint. Cosmetologists even use foil when coloring or highlighting a client's hair. They may also mix up the hair color in a makeshift bowl of aluminum foil.
