Sour milk can really ruin a meal. That's why Quirky and General Electric have joined forces to come up with a device that watches the milk when you can't. The Milkmaid is a jug that you pour your milk into. Inside the jug, pH and temperature sensors continually monitor the state of the milk. The information is relayed to an electronic base that can then send a message to your phone if things don't look right. If that sounds like a lot of work just to keep from getting an unexpected mouthful of yogurt, then how have you made it this far in the article?
