DENVER (CBS4) – A science fair project was a labor of love for a local eighth-grader. She came up with a way to help cancer patients, in particular, her father.
CBS4 Health Specialist Kathy Walsh met sharp, young Ellie Mackintosh. She’s just 13, but already an inventor. Ellie’s father is especially moved by what she’s accomplished and why.
“My goal was to create a mouthwash,” Ellie said. “I used 40 people to test it.”
