Explanation: A sun basket is basically a parabolic mirror made from paper mache supported by jute fabric and held in place by a bamboo frame. Aluminum foil is used as the reflecting lining and is glued to the inner side of the basket. Rubber and bakelite are thermal insulators. Gold is an expensive metal and is not used to make solar basket.
