In the video, there are two children wearing safety goggles. The boy is wearing a pink shirt and the girl is wearing a white shirt. They are both holding a yellow sponge. An adult, who is wearing a black jacket, is also holding the sponge and appears to be instructing the children on how to use it. The background shows a classroom setting with a whiteboard and various educational posters. The children seem to be engaged in the activity and are attentively listening to the adult.
