According to Sue Quinn of The Guardian, Harvard wizard Dr. David Edwards -- "the Dumbledore of food technology" -- has developed WikiCells, an edible membrane made from a biodegradable polymer and food particles which can "imitate 'bottles' found in nature, such as grape skins."
So far, Dr Edwards and his team at Harvard's Wyss Institute have created a tomato membrane containing gazpacho soup, an orange membrane filled with orange juice that can be sipped through a straw, a grape-like membrane holding wine and a chocolate membrane containing hot chocolate. He believes pretty much any flavour is possible.
He recently told Harvard's campus newspaper Harvard Crimson that his team was working on a prototype bottle that had an eggshell-like hard coating in addition to the membrane that could be peeled off or eaten whole. "In the near term, we will be encountering WikiCells in restaurant settings," he told the paper. He then plans to expand WikiCells into shops and supermarkets.
