In the video, a person is seen using a yellow ice cube tray to make ice cubes. The person first removes the ice cube tray from the freezer and then proceeds to fill it with water. After filling the tray, the person places it back in the freezer to allow the ice to form. Once the ice is frozen, the person removes the tray from the freezer and begins to remove the ice cubes from the tray. The person then places the ice cubes on a table and picks them up one by one, examining them.
