In the video, a person is seen using a glue gun to apply glue to a piece of cardboard. The person then places another piece of cardboard on top of the first one, aligning it with a cut-out hole. The person then uses their hand to press down on the cardboard, presumably to ensure that the glue is properly applied and the two pieces are securely attached. The video focuses on the person's hands and the cardboard, with no other objects or background details visible.
