In the video, a group of children are sitting around a table, playing with a Lego set. The Lego set is made up of various blocks and pieces, and the children are actively engaged in building and rearranging the pieces. The table is covered with a black cloth, and the children are focused on their play. The Lego set appears to be a castle or fort, with towers and walls made up of different colored blocks. The children are using their hands to pick up and place the blocks, and they seem to be enjoying themselves as they work together to create their Lego structure.
