Sour Milk Detector

This device that is sensitive enough to know whether milk has actually turned sour, making it a no-brainer to be installed at your local grocery store’s checkout counter. At least if you don’t have a cat at home, you will be able to know there and then when the milk you purchased has spoiled. This unique device is sensitive to the thickness of a container’s contents – should it vibrate too slow or faster than normal, an alarm will be triggered so that you can pick up a fresher carton of milk. Try to read the expiry date the next time though, it will save you and everybody else in line a whole lot of time instead.
