Pint size heroes at Ohio Elementary School in Watertown.
The American Red Cross held a blood drive there Tuesday. Leading up to it, the school taught kids about what blood is and how it's important for the body.
That encouraged the kids to bring their parents in to donate blood.
Second grader Aidan Booth came out in support of the event. He had a disease and his life was saved by a blood donor.
"The sickness was killing more and somebody gave blood, so it put more blood in my body. It saves other people's lives," he said.
The students who got their parents to donate blood will receive an American Red Cross Blood Donor Recruitment medal.
