In the video, a person is seen holding a blue cube in their hand. They then place the cube on a tray that already has several other blue cubes on it. The person then picks up another cube and places it on the tray as well. The tray is filled with these blue cubes, and there are other colored cubes on the tray as well. The person continues to place the cubes on the tray, creating a pattern of different colored cubes. The cubes appear to be made of a gel-like substance and are translucent. The person's movements are deliberate and careful as they place each cube on the tray. The tray is placed on a table, and there is a blurred background that suggests the setting may be a kitchen or a craft room.
