In the video, a person is pouring a clear liquid from a blue bottle into a small container. The liquid is being poured onto a white powder that is already in the container. As the liquid is poured, it begins to react with the powder, creating a foamy substance that grows in size. The person continues to pour the liquid, and the foam continues to expand, eventually filling the container. The foam is white and appears to be thick and fluffy. The blue bottle is held at an angle, and the liquid is poured steadily into the container. The background is a light blue color, and there are no other objects or people visible in the video.
