Question

1 What causes the colours in ink to move across absorbent paper?​

Answer 1

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.
