Magic milk jug tells you when the milk has spoiled

If you've ever had the unfortunate experience of drinking spoiled milk, you'll appreciate this concept jug that measures the pH to determine whether the milk inside is still good.


I make my cappuccino while still half asleep each morning. So a few weeks ago, I did notice that the milk frothed a bit funny, but I didn't actually process that information until I took a sip. What normally hits me as a sweet, sweet drug was instead unceremoniously spit into my sink, much to the amusement of my children.

Entertainment value aside, I'm not a fan of spoiled milk. The R&D team at Cravendale, a British dairy, is currently researching a new milk jug designed to prevent future milk tragedies like mine thanks to a pH sensor in the jug's base. The sensor monitors the acidity of the milk in the jug and outputs either Fresh or Sour to an integrated LCD screen. An alarm will also sound when the milk sours, so that you don't accidentally drink it if you're too tired (or too illiterate?) to read.

News of the jug--which is still only a concept--was originally posted on March 29, which led to some speculation that it was an April Fools' Day joke. But the company insists that it's legit, and that it'll be available sometime in the near future. I'm hoping to snag it soon.
