In a kitchen in the south of England, two women are devising a recipe that could change the world.
On a kitchen table two young women have assembled a variety of items. There are brown bottles, bags of white powder, a pestle and mortar, a collection of funnels, a roll of silver gaffer tape. There is a drill. There is a whisk.
Are they making bombs? Are they making drugs? No. They are doing something far more likely to change the world we live in. They're making their own version of Coca-Cola.
