Have you ever accidentally drank sour milk? I have encountered a few incidents where I drank a bottle of expired milk. Yes, I tend to open and drink a glass then keep it inside the fridge. Few days later, I will look for it back, but sometimes I’m out of luck because it’s already spoiled.

I’m so careful about this that I sometimes throw away milk which is still good. And as I wonder if there is a way to detect the milk freshness, I came across this magic jug which can test the milk for you. It tells you through the LCD display whether it “fresh” or “sour”.

As milk turns sour, it will become more acidic. This chemical reaction will trigger the sensor in the bottom of the Cravendale’s jug that detects the drop in pH and ring the alaram. This gives us a realiable way to tell the milk’s freshness so you could stop you from drinking spoiled milk.

This interesting stuff is a must have things on the world’s most expensive house . The rich have to get the experience on this amazing thing.
