In the video, a person is seen holding a clear glass ball in one hand and a silver-colored metal cap in the other. The person proceeds to attach the metal cap to the top of the glass ball, creating a seal. The person then uses a small tool to secure the cap onto the ball, ensuring it is tightly fastened. Throughout the video, the person's hands are the main focus, with the background remaining out of focus. The glass ball appears to be of a medium size, and the metal cap is small and circular. The person's movements are precise and deliberate, indicating a level of expertise in handling such materials.
