Answer:
As the water travels up the paper strip (similar to capillary action in plants), it dissolves the ink and pulls it up the paper too. ... Some pigments dissolve in water easier and are pulled with the water farther up the paper. Others are more attracted to the paper and move more slowly.

Answer:
When you dip the paper in water, the dried pigments dissolve. As the water travels up the paper, it carries the pigments along with it. ... Since the water carries the different pigments at different rates, the black ink separates to reveal the colors that were mixed to make it.
