A pair of YouTube pranksters tricked a self-service Amazon store into giving them food for free after swapping it for weighted bags of sand on the shelves.
Archie Manners and Josh Pieters, who have almost 1.5 million channel subscribers, managed to make off with £25 worth of food after outwitting the unmanned and cashierless shop.
Their latest video shows how they got around more than 2,000 sensors watching their every move and scales on the shelves at an Amazon Fresh store in London.
