While eating lunch at Fratt Elementary in Racine, Wisconsin, fourth grader Essie Collier saw one of her classmates choking and ran to her aid.
The nine-year-old performed the Heimlich maneuver on the choking girl, clearing her airway and allowing her to breathe again.
Everyone is impressed with Essie’s life-saving action, which she says she learned from Youtube when she was seven and it has stuck with her.
