In the video, we see a person's hand holding a hammer and using it to drive nails into a piece of wood. The wood has many pre-drilled holes, and the nails are being hammered into these holes one by one. The person's hand is steady and precise as they drive each nail into the wood. The hammer is made of metal and has a wooden handle. The wood is a light brown color and appears to be a plywood or similar material. The nails are silver and have a flat head.
