In the video, a person is seen using a hot glue gun to apply glue to a piece of cardboard. The glue is applied in a zigzag pattern along the edge of the cardboard. The person then folds the cardboard along the glued edge, creating a crease. The process is repeated several times, with the person applying glue and folding the cardboard in the same manner. The video is shot against a blue background, and the person's hand is visible as they work on the cardboard.
