In the video, a person is seen using a plastic bottle to make a sandcastle. The person first fills the bottle with sand and then places it on a pile of sand. They then use their hands to pack the sand into the bottle, creating a cylindrical shape. The person continues to pack the sand into the bottle, making sure it is tightly packed. Once the sand is packed into the bottle, the person removes the bottle and reveals a sandcastle. The sandcastle is small and cylindrical, with a smooth surface. The person then uses their hands to remove the sandcastle from the bottle, revealing the sandcastle's base. The sandcastle is made of a light brown sand, and the bottle used to create it is clear with a red cap. The background of the video is a plain white surface, and there are no other objects or people visible in the video.
