Technology is not limited to phones. Cravendale, a UK-based dairy, has developed a new milk jug. The LCD display says “Fresh” (as in the picture) if the milk inside is fresh. A PH sensor in the jug’s base senses when the milk turns sour. The LCD display then changes from “Fresh” to “Sour.” In case you’re one of those people who don’t read, there’s also an alarm. If you still drink the milk, then you’re contributing in a small Darwinian way to the improvement of the overall human gene pool. No ETA yet on when available for purchase.
