St George flying with water-filled trash bins

St. George dropped down next to a plastic trash barrel. A man with scruffy blond hair yanked his hose away and stuck it into the next container. “Should have another one ready in about two minutes,” he told the superhero, gesturing at one of the other barrels.
St. George nodded and worked his fingers underneath the trash barrel. He grabbed the rim with his other hand and heaved. His feet lifted up off the Big Wall and he soared back to the flames, water sloshing out as he went.
A nearby lawn with a medium-sized apple tree burned. He swooped down through the air and shook water out of the barrel. It splattered through the leaves of the tree and smothered most of the fire.
