A prestigious prize was won by a group of middle school students from Manhattan, USA for devising a product any mother would love: a pitcher that alerts you when milk has gone bad.

Using the 5,000 dollars in prize money, the students are already fine-tuning their design.
"We're going to work on it a bit more and then get it patented," the New York Daily quoted 11-year-old Stuart Bruce-Noble as saying.
The group of 10 sixth-graders started working on their intelligent milk pitcher last fall.
That's when the organizer of the competition, the non-profit FIRST, announced that this year's challenge will focus on food safety.
The brainy bunch of students got their inspiration for the device from a troubling news story, that several California kids had fallen ill after drinking contaminated milk.

Under the guidance of technology teacher Hau-yu Chu, Chen and her friends put their heads together and dreamed up the revolutionary milk container.

The pitcher is made up of eco-friendly plastic and glass and is designed to detect the PH levels in milk.
When the milk turns sour, the pitcher's elaborate alert system is automatically triggered.
"It has a flashing light for people who are deaf, and we also have a low frequency alarm so people who are blind can use it," 12-year-old Michael Monticciolo said.
The experience has left Harry Freedman and his fellow inventors dreaming of pursuing careers in engineering.
"Inventing things is pretty cool," 10-year-old Freedman said.
