The video shows three boys sitting at a table, each with a bowl of marbles in front of them. The boys are picking up marbles and placing them into a tray on the table. One of the boys is holding a marble up to the camera, showing it to the viewer. The marbles are of various colors, including blue, green, red, and yellow. The boys seem to be sorting the marbles by color or size. The table is covered with a white tablecloth, and there is a computer monitor in the background.
