The image shows three young boys sitting at a wooden table in a classroom. They are looking intently at a small glass jar with a blue lid and a white substance inside. The jar appears to be filled with water and there is a blue funnel attached to the top. The boys are leaning over the table with their hands on the table, as if they are trying to figure out how to use the jar. In the background, there are other students and a fan hanging from the ceiling. The boy on the left is pointing at the jar with his finger, while the boy in the middle is looking at it with a curious expression.
