In the video, a young girl is seen pouring a pink liquid into a bowl of colorful slime. The bowl is placed on a white table, and the girl is wearing a pink shirt. She pours the pink liquid from a bottle with a red cap and a label that reads "GUE". The liquid is poured in a circular motion, creating a swirl of pink in the center of the bowl. The slime already in the bowl has a rainbow-like pattern with blue, yellow, and pink colors. The girl then uses a yellow spoon to mix the pink liquid into the slime, creating a marbled effect.
