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.
The Manhattan Academy of Technology students' "smart milk pitcher" came second at the FIRST LEGO League Global Innovation Awards, beating more than 250 teams from 15 countries.
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.
"I wanted to do something about it," 11-year-old Jenny Chen said.
Under the guidance of technology teacher Hau-yu Chu, Chen and her friends put their heads together and dreamed up the revolutionary milk container.
Made with eco-friendly plastic and glass, the pitcher is designed to detect pH levels in milk.
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.
