Africa | 'Ukhamba' basket from the Zulu people of South Africa | Weavers use strips of naturally waxy palm fronds wrapped around coils of wild grasses. | Some baskets are still used for liquid storage in the rural areas of South Africa. Watertight baskets are readied by rubbing wet cornmeal inside. When liquid is added, the coils swell. Some leaks through, evaporates, and cools the contents.
