In the video, a person is seen pressing their finger into a container filled with green slime. The slime appears to be of a thick consistency and has a bright green color. The person's finger is shown pressing down into the slime, causing it to spread out and create a small indentation. The action is repeated several times, with the person's finger being pushed down into the slime and then lifted back up, leaving a temporary impression. The slime slowly returns to its original shape after each press. The person's nail is painted with a purple polish, and the container holding the slime is not visible in the video.
