Foil (/m/02vk7kj)

A foil is a very thin sheet of metal, usually made by hammering or rolling. Foils are most easily made with malleable metals, such as aluminium, copper, tin, and gold. Foils usually bend under their own weight and can be torn easily. The more malleable a metal, the thinner foil can be made with it. For example, aluminium foil is usually about 1/1000 inch, whereas gold can be made into foil only a few atoms thick. Such extremely thin foil is called leaf. Leaf tears very easily and must be picked up with special brushes. Foil is commonly used in household applications. It is also useful in survival situations, because the reflective surface reduces the degree of hypothermia caused by thermal radiation.
