group of young boys playing a game outdoors

group of young boys playing a game outdoors. Three of the boys are centrally positioned in the frame. Two of the boys are leaning forward, with their backs arched, trying to accomplish a task with a clear glass bottle placed on the ground between them. The third boy is slightly behind, seemingly observing. All the boys are wearing casual attire, mostly shorts and t-shirts. One of the boys has a piece of straw tied to his back. They are playing on a concrete surface that appears slightly damp. The background shows a partially constructed brick wall and green foliage, suggesting a rural or suburban environment. Another boy stands in the background, looking on. The day appears sunny and clear.
