The video shows a close-up of a clear glass as a dark liquid is poured into it. The liquid is poured from above, and as it hits the bottom of the glass, it creates a layer of foam on top. The foam is a lighter color than the liquid, and it rises to the surface, forming a distinct layer. The glass is placed on a surface, and the background is blurred, focusing the viewer's attention on the glass and the pouring liquid.
