In the video, a person is seen holding a black object in their hand. The object appears to be a pen or a similar writing instrument. The person then proceeds to use a hot glue gun to apply glue to the object. They carefully apply the glue to the object, ensuring that it is evenly distributed. The person then proceeds to attach another object to the first one using the hot glue gun. The second object is also black and appears to be a cap or a lid. The person aligns the two objects and presses them together, ensuring that the glue holds them in place. The video ends with the person holding the newly assembled object in their hand.
