In the video, a person is holding a knife and using it to cut through a red piece of paper. As the knife moves through the paper, it reveals a small pile of ants underneath. The person continues to cut through the paper, and more ants become visible. The ants are dark in color and are crawling around on the red surface. The person's hand is steady as they cut through the paper, and the ants seem to be unaffected by the cutting process.
