group of boys participating in a game outdoors

group of boys participating in a game outdoors. They are lined up, each with a water bottle tied to a rope around their waist. They are bending over, trying to use their waist movements to knock over the bottles. The ground appears to be concrete or a similar hard surface. Other children are sitting and watching the game. In the background, there is a building, a banner with an image of a red rooster, and people, some wearing red shirts.
