Aluminium foil is used to help promote a suntan and to help keep picnic food cool.
Sun worshippers use a large aluminium covered sun reflector to improve on their tans. A bronzed couple lie beside an open air swimming pool. C/U of them lying in the sun. C/U of a woman applying sun cream.
Man carries a large piece of board which is covered with aluminium foil. He positions the reflector beside a woman in a swimsuit who lies on a lilo - great sunglasses. The man opens a picnic basket and pulls out lots of packages wrapped in foil. Narrator observes that foil can keep things cool as well as for roasting (not chickens but humans).
The couple begin their picnic beside their foil reflector "this way we can get brown all over without being turned slowly on a spit..." observes the narrator.
