Tons of milk are thrown away each year in the US alone. To combat this problem, the guys at
Cravendale have invented a magic milk jug.
The issue of thrown-away milk is more serious than it appears, considering it generates massive
amounts of CO2 emissions, every year. But a simple British invention could make things a lot better for
the environment. The Cravendale research team has studied the bacteria that turns milk sour and
managed to create a milk jug that detects spoiled milk.
The Cravendale milk jug features a PH sensor, built in its base, that measures PH acidity and displays
its condition on a small LED screen. If the milk is drinkable, it will read “Fresh”, if it has gone sour, it
will show “Sour”. (http://cravendale.unit9.com/)
