In the video, a person is seen holding a piece of wood with a nail inserted into it. The person then picks up a nail and places it on top of the one already in the wood. The person then taps the nail with a hammer, driving it deeper into the wood. The person repeats this process several times, each time driving the nail deeper into the wood. The person's hands are visible, and the background is a dark color, possibly a table or workbench.
