In the video, a person is seen holding a cardboard tube in one hand and a glue gun in the other. The person proceeds to apply glue to the opening of the tube using the glue gun. After applying the glue, the person places a white paper circle on the opening of the tube and presses down to ensure it is secure. The person then picks up the glue gun again and applies more glue to the paper circle. Finally, the person picks up a blue pen and uses it to trace around the edge of the paper circle on the tube, creating a neat and precise line. The video ends with the person holding up the finished product, a tube with a white paper circle attached to it.
