There are four children in this video. They all seem to be cooking their own thing. One child seems to be basting the rocks in the red triangular pan. The girl is filling her bottle with a metal measuring cup. The child in the foreground is scooping and spreading his ingredients in the large white tub. The fourth child first tries to scoop sand with a plastic measuring cup, but it doesn’t work because the blue tray is too skinny. He does start to fill the cup with his hands.
