12-year-old's invention wins $20,000

Lydia Denton, from North Carolina, may be young, but she just won the CITGO Fueling Education Student Challenge, earning $20,000 by creating a winning invention of a car set device that detects when babies have been left in a hot car. It can prevent them from dying.

The soon-to-be seventh grader was inspired to make the invention after watching news and seeing that babies were being left in hot cars, often by accident. "What I wanted was a device that had the ability to get 911 there to save a baby if parents did not respond. And I wanted something everyone could afford." A current student at a Title I school, she notes that "new cars come with warnings and smart car seats," but many of her friends and family don't have these yet.
