In the video, a person is seen pouring a pink liquid into a clear glass jar. The liquid is poured from a height, causing it to splash and create bubbles. The jar is placed on a white surface, and the background is blurred, focusing the viewer's attention on the pouring action. The pink liquid appears to be a viscous substance, possibly a slime or gel, and the jar is marked with measurement lines. The pouring is done with precision, and the liquid fills the jar gradually.
