The video shows a person's hand holding a small metal tin. The tin is opened to reveal a small compartment inside. The person then places a small metal object into the compartment. The object appears to be a tiny metal piece or screw. The tin is then closed, and the person picks up a black marker and places it on the table. The person then picks up the tin and places it on the table next to the marker. The video ends with the person picking up the tin again.
